Why You Absolutely Should Not Use Baking Soda as an Exfoliator

Skin Care

Stop putting baking soda on your skin. Let me repeat that: Stop putting baking soda on your skin. Baking soda exfoliation is a total favorite of the home remedy set. I’ve seen it in a ton of places, including this article on what Emma Stone uses on her skin, and every time, it makes me cringe a little. Baking soda isn’t just ineffective, it’s actually damaging to your skin. Don’t believe me? Read below and see the science.

Baking Soda + Water is ALKALINE

Let’s start with a little chemistry lesson. Forgive me, chemistry buffs, since this will be information you already know. We’ll start with the Brønsted-Lowry concept, which says that acids are proton donators that are able to give a proton (the hydrogen cation or H+), and bases are proton acceptors that are able to receive a proton (H+). Bases neutralize acids by bonding with the acid’s hydrogen ion (General, Organic, and Biochemistry).

But, like it or not, the world is not a simple, black-and-white place of acids and bases. Thrown in there are also amphoteric molecules (ions). “Amphoteric” means that a substance has the ability to react with both acids and bases. And some of these amphoteric substances are also amphiprotic, which means they can donate and accept a hydrogen ion. Baking soda’s chemical name is sodium bicarbonate, and bicarbonate is an amphiprotic ion, so it can both take and lose a hydrogen ion. So, this means that baking soda reacts with acids and bases by either donating or accepting a hydrogen ion. But bicarbonate is a stronger base than it is an acid, so it’s more likely to accept a hydrogen.

When you’re making baking soda exfoliator, however, you’re mixing it with water, so the question is what’s the final pH of bicarbonate (HCO3-) and water (H2O). Here’s the chemical formula:

HCO3- + H2O → H2CO3 + OH-

See what happens there? Because it’s a stronger base, it tends to create HO-, rather than H3O+. What this means is that when you dissolve sodium bicarbonate in water, the solution tends to be more alkaline.

See That It’s Alkaline for Yourself

To really prove this, I decided to test it out and mix baking soda with water and test the pH to show you.

When we mixed baking soda and water (more than you’d use for a scrub) and tested it, the pH was about 8.

So Why Is Something Alkaline Bad for Skin?

The pH of the products you use is super important for maintaining healthy skin. Here’s how the pH scale works: It runs from 0-14 with 7 meaning neutral. Anything above 7 is considered alkaline, or a base, and anything below 7 is considered an acid. The skin naturally falls somewhere around 4.5 to 6.5, and is maintained by sebaceous glands, sweat glands, and normal skin flora, among others. This skin acidity is called the “acid mantle” (Exogenus Dermatology).

When you apply a product with a high pH, aka something alkaline, negatively disrupts the skin barrier. A study on skin products found that using an alkaline cleanser, even once, can do damage to the skin (Dermatology). An alkaline cleanser disrupts the skin’s acid mantle (affecting the skin barrier), and changes the bacterial flora composition on the skin and the activity of the enzymes in the upper layers of skin, as these have an optimal pH level. And the damage is cumulative: The longer you use it, the more damage it does to your skin.

So, with baking soda and water, you’re already disrupting the acid mantle, but you’re also manually exfoliating, making it even more damaging and drying.

Because of this, you want mildly acidic products, which help the skin hold moisture and also improve the skin barrier. But it’s important that they’re mildly acidic, as you can, in fact, go too low. If you go too low with products, you risk skin irritation, sun sensitivity, and hyperpigmentation (International Journal of Cosmetic Science). That’s why we don’t recommend that you use straight lemon juice on your skin, for example.

Verdict: Trick

Skip the baking soda skin exfoliating and stick to something gentler with a lower pH. This is why I highly recommend sticking to professionally formulated products for your beauty routine. It’s not that I don’t love a good home remedy, but I think it’s easy to become misinformed and misuse products like baking soda in ways that does more harm than good in the long run.

Use Gentle Forms of Exfoliation Instead


I also highly recommend using gentle forms of exfoliation, like the papaya enzymes found in Kate Somerville ExfoliKate, or physical exfoliative methods as found with the ViaBuff Facial Exfoliator. The ViaBuff Facial Exfoliator comes in four different levels for varied skin concerns, including:

Level 1: Extra Gentle
Ideal for Oily Skin, Acne, Psoriasis

Level 2: Mild
Ideal for Normal Skin, Eczema

Level 3: Moderate
Ideal for Dry Skin, Ingrown Hairs, Keratosis Pilaris, Waxing

Level 4: Clinical
Ideal for Very Dry Skin


The ViaBuff Facial Exfoliator is non-sensitizing, non-irritating, cruelty-free, and dermatologist-tested. I use the ViaBuff Facial Exfoliator Level 2 (green) daily, and I have never had more beautifully smooth or glowing skin. I’m not kidding — it’s a must-have! And for $4, it may be the best skin care bargain ever on FutureDerm! I would personally much rather spend my time or money on a solution I know is customized to work for my skin type and concerns than mixing up sodium bicarbonate (baking soda) in my kitchen. Give it a try!

    Ive been suing baking soda as a scrub for a couple weeks. Its the ONLY thing that clears my skin up SO well. Ive never had my skin this clear in 13 years!!! (since puberty) I dont want to use anything else like store made chemical junk. They all broke me out. neutragena, proactive, clean and clear, apricot scrub……please help! I used to do baking soda and ACV to balance it..but I felt it was weird so i brought it down to just BS. I cant stop using baking soda. It doesnt dry my skin whatsoever. HELP!!

    I just want to be clear that you base all of your evidence for this on a study that was conducted in 1997 where 10 kids washed their faces once with detergent and alkaline soap. The pH of the alkaline soap they used was 9.5. The acidity of the baking soda, based on your image, is 8 pH or less.

    So not only is this study outdated and far reaching in its conclusions based on a face wash conducted over one day, but they used something more alkaline than baking soda in the first place. It’s almost like you just put a link to something that was complicated with the idea that nobody would actually go to it and try to make sense of it.

  • Ayamuri

    I don’t want to use baking soda on my face but my legs. I have “strawberry legs” which has been the case for years. My pores are rather clogged and I’d like to see if warm bathing (instead of showers like usual) with a little baking soda might help out. I’ll stick to using Noxema on my face as that usually works for me as long as I stick with it.

    The only other beauty product I’d like is a treatment for dark spots or scars (and a home treatment would be even better. I dislike expensive creams). I have bad dark spots on my back and face from acne as a teen.

  • Chelley

    I use bi carb as an exfoliator mixed with honey , I also was,my face with Oatmeal Soap and I’m 46 this year and only look about 35-37 and I also use aloe vera gel or sorbalene cream.

    I know for a fact that regular use of bi carb on the skin clears up very bad Acne as one of my children’s teachers had very bad inflamed acne and I told her to use bi carb … About a few months later her acne was cleared up even the acne scarring and her skin was renewed , rejuvenated and glowing and she was so happy and confident and looked very beautiful

    So I dont agree that Bi carb is everything made out to be as a natural remedy for DIY skin care

    Sorry but Bi Carb is an anti cancer agent and Big Pharma doesn’t want anyone using healthy natural treatments against their chemical products

    • Ash

      Its the ONLY thing that clears my acne. I use it with water and put on a nice moisturizer from trader joes. Ive never had such clear skin. Ive been using Bi carb for a couple weeks and dont want to turn to anything else! So I agree with you. What will happen to my skin? everything..and I mean EVERYTHING else breaks me out.

    You lost all credibility with me the moment you became an advertisement for Kate Somerville and Via Buff. The. When someone says their skin has never looked better, you directly contradict your own statement of “using it just once you have already irreparably damaged your skin” by saying ” it would depend on how much you use baking soda.” You are correct, it is all too easy to be misinformed by information on the Internet, however when someone tries so hard to sell me a product, I have often found they are the ones providing misinformation.

    If you mix an acid and base such as baking soda and lemon which are in most diy recipies wouldn’t it be considered a neutralized buffer? Making it on average a 5.1 ph, the same average as your natural skin ? I’m no chemist but it seems logical to me

    Everyone here, whomsoever is bothered about how my skin will get rid off the damage caused by baking powder. So guys just relax and don’t apply anything else anticipating cure. Rather leave skin on its own. It will get healed up on its own. Nothing is permanent(except acne scars) so as the damage. Our body us having that schema to get well on its own. Just give it time and relax.

    I mix 2 parts rice flour to 1 part baking soda. Rice flour has a ph of 2-3 so I figure the high ph of the bicarb is counteracted by the acidity of the rice flower. Works out to a ph of about 6.8 with my ratios.

  • Sherri

    Someone directed me to this page to read, but I can honestly say I won’t be giving up my BS and water scrub followed by diluted vinegar. I’ve been doing it for 20 years and my skin glows. Every time I’ve allowed someone to scare me out of it and gone on brief stint a of using beauty products, I lose that glow. I have the honor of being told at our school reunions that I, at 51, have aged the least of the class. And, no, it doesn’t run in my family. I have a sister who is a year older and a sister who is three years younger than me, but they both look at least 10 years older than me.

  • HeatherMaybe

    I had acne for about 6 ridiculous and horrible years of my life, but now my skin is the best its ever been!!! I quit the expensive face washes and toners and cleansers and spot creams about a year ago and now I use bicarbonate of soda every 4 days ish, I rub it in to a paste apply over face and then quite quickly wash off and then baste my face in olive oil for 5/10 mins and then hot cloth it off… my skin is never dry, always glowing and just looks the best it has done in years!!!! I do have quite oily skin naturally though. This article does look like a strange smear campaign with olay product advertisements, and the way natural remedies are framed in this article suggests a strong bias. I wouldnt trust this article. I would test it out on a patch near your ear or something and see if it can actually cause harm. I dont actually get how it could be damaging if my skin looks and feels so healthy. This page is trying to sell really expensive products lmao. Feel sad for people wasting their money on this!!!

  • I use an aluminum-free Sodium Bicarbonate in my deodorant formula which is a coconut oil base. The pH is never over 7.5 on all of my batches and after over 1000 sales, only two have been reported as “irritated.” That could be attributed to many things like shaving with a dirty/old razor or not waiting a few days before introducing a new product.

  • paola

    I’ve been using baking soda for years as a regular exfoliate mixed with honey, which helps to balance out the PH…but beyond this discussion, you should be aware that many commercial products contain PLASTIC BEADS which wash down our drains and into lakes and oceans (think : plastic fish food!?) and obviously, cause major harm to our environment. Canada is actually in the process of banning these beads in exfoliating products. http://www.pri.org/stories/2015-09-30/why-canada-banning-microbeads

    I was given the baking soda tip when I was a teenager from a modeling/etiquette/beauty professional who was about 50 years old with great looking skin, and used very simple washing and moisturizing products (her favorite moisturizer? A good diet and lots of water!). I was convinced 🙂

  • Phoebe

    I noticed in your comments that the effects of baking soda depends on how much and how often you use it. Despite your warning on baking soda being bad for the skin, i’m still going to try it out. My skin isnt sensitive that products with low ph like cetaphil doesnt really take effect on my skin lol. If I were to use baking soda as a facial scrub how much and how often do you suggest me to use it?? Because I dont want to damage my skin too much! You said the skin will heal after 12 hours, so it’s no big deal to use it once or twice a week? With coconut oil added to the mixture and usage of moiturizers after, will this be enough to repair or prevent damage?

    • Nicki Zevola

      Hi @Phoebe – I don’t support or recommend using baking soda as an exfoliator, and I don’t feel comfortable answering how much or how often to use for that reason. My apologies. Maybe someone else will answer that here in comments.

  • nikki

    I used baking soda. Once. It was awful. Initially I mixed it with distilled water and oil. My skin did feel super smooth and glowy. But dried out the next day. I have relatively stable skin if I dont mess about with it. But honestly from personal experience…its not for me.
    I found this article interesting though thanks. I was advised by my dermo to not use exfoliants. She is against them unless they are enzyme based and done by a pro. She was right. I followed her advice… stopped scrubbing and within 3 month my skin adjusted and I never have flaky scaly buildup. Once every couple month I do an enzyme mask and thats it. More is less in my case.

  • Ani

    Um… Aren’t you supposed to mix it with an oil, like grapeseed oil or almond oil or something? Not water…

    • Nicki Zevola

      @Ani – Even so, the pH of the baking soda (pure sodium bicarbonate) would still be a problem.

  • bikebum

    I’ve been using baking soda to treat my sebhorreic dermatitis for over 2 years. It works great for me, and the stuff a dermatologist recommended did not.

    As Reader pointed out, the ocean is about the same pH as baking soda, and spending a lot of time in sea water does not seem to have a negative effect on skin health. A day of surfing actually makes my skin feel great, although a little dry but some lotion fixes that.

    This article sounds like fear-mongering aimed at convincing people to fork out the big bucks for fancy skin care products.

    • samantha

      am i the only one who’s noticing the products they’re shilling at the bottom?

      try the baking soda out on your skin. see for yourself. i have oily skin, and i started exfoliating with BS (lol) 3 nights ago. made such a difference! my skin is glowing. i dab water/BS on blemish and they diminish a lot overnight. my skin gets kind of dry, so i’ll use it with coconut oil in the future.

      i think this study was done just to get people to buy their product.

      • Nicki Zevola

        Hi @Samantha —

        I’m glad that the method worked for you. It won’t work for most people.

        The purpose of this article is not to try to get people to buy our products or any of our advertisers’ products. If I wanted to, I could team up with Arm & Hammer and say baking soda is wonderful for the skin and have them as a huge sponsor on the site. I could have farmers and natural product companies advertising their foods and products as skin care miracles.

        But I won’t accept most of them as advertisers.

        I say that baking soda (i.e., 100% sodium bicarbonate) is bad for the skin when used as a DIY because, for most people, it is. I’ve had a lot of readers write to me about these so-called “remedies” that have absolutely destroyed their skin.

        Natural products and ingredients are still made of chemicals. If you don’t believe me, check out the ingredients in an all-natural, organic banana: https://jameskennedymonash.wordpress.com/2013/12/12/ingredients-of-an-all-natural-banana/

        We are all made of chemicals. Everything has a chemical composition. Natural is not always good and synthetic is not always bad. The beauty industry caught the tail end of the food industry’s change in philosophy, but food is not skin care. Your digestive tract evolved to ABSORB. The digestive tract easily breaks down foods and extracts key ingredients. But the skin evolved to PROTECT. The skin needs to have high concentrations of key ingredients and penetration enhancers added for it to even be able to get to the good stuff!

        Hope this helps.
        All the best,

        • Surgio

          “The skin needs to have high concentrations of key ingredients and penetration enhancers added for it to even be able to get to the good stuff!”

          That’s completely made up.

    • Nicki Zevola

      @bikebum –

      The purpose of this article is not to try to get people to buy our products or any of our advertisers’ products. If I wanted to, I could have all sorts of natural product companies advertising their products as the skin care miracles. I could have grocery stores and DIY publications advertising here for their at-home DIY remedies. If money was my sole goal, honey, that’s where the money is right now! The big explosive growth is with telling the public synthetic products will harm them — that’s what has The Honest Company laughing all the way to the bank, for instance.

      No, I’m saying this because this is my 100% honest to God opinion. Not all natural remedies are good and not all synthetic remedies are bad. Natural product companies claim “safety” and synthetic product companies claim “efficacy.” In truth, nearly all synthetic products out there on the market today are both safe and effective when you break each ingredient down, study the concentrations in each product, exclude studies that are not relevant at that concentration or method of administration, and evaluate them as a whole.

      I truly believe baking soda (100% sodium bicarbonate) is bad for the skin, and I stand by that. I don’t hate all home remedies, as you’ll see here: https://www.futurederm.com/baking-soda-and-apple-cider-vinegar-plus-24-more-home-remedies-confirmed-or-debunked/

      baking Soda never dries out my skin. WOuld it be ok for me to continue using it? My skin glows now and Ive never had problems. I use BK once a day.

  • Candice

    Okay…so I’m also frustrated. The internet is lovely because it’s “answers right at your fingertips” but in many cases, there’s no concrete facts that have any truth behind them. But, oftentimes in life, you must weigh the pros vs. cons and chose. You can’t have anything completely perfect. So here’s my point; baking soda is disruptive to your pH levels in your skin, and it can be drying and irritating. But we can ingest baking soda, it goes in food, it’s pretty much safe all across the board in a sense that it has no direct link to causing cancer, its’s safe to use around babies, etc, etc. Now the other side…women averagely put anywhere from 380-600 different chemicals on their bodies daily. With the anti-aging products, moisturizers, toners, foundations, the list goes on. 500 chemicals?! That’s insane. And if you don’t believe me…do the research yourself. Next time when your getting ready, make a point to looking at the ingredients on EVERY product you use for body, face, hair, makeup and write everything down. It”s chilling how long the list gets, youll pobably give up a quarter of the way because youll already see. But then look up what each of the ingredients are….and then tell me that baking soda is bad.

    • Nicki Zevola

      Ah, @Candice…you had me for a while there, totally in agreement till the end. If you add up the AMOUNT of each of these “500” ingredients, it’s still less than the amount of 100% sodium bicarbonate you’re putting on your skin. Concentrations really matter. A 0.0025 mg dose of a pH balancer or preservative in a skin care product does nothing to your skin or your health, but it does help the product to be packaged in (and remain in) the right pH range for your skin, and to have a longer shelf life.

      • Bob

        1. That baking soda, in any amount, is safe. It may change the skin pH causing minor irritation. If this happens stop using it until the skin returns to normal. Otherwise, it’s cleaning, deodorizing, and removing all that nasty make-up; leaving only healthy skin.
        That said, baking soda every day might be too much. Let’s say once a week as a means ot remove all the gross stuff on skin–it works amazing, and again, completely no danger.
        2. Make up, on the other hand, is dangerous. The shit in that is going to give you cancer, no matter how much you use. Good luck with that stuff.

        Dear Nicki, I really appreciate your information. I recently developed seborrheic dermatitis on my forheead and also have extreme drying around my eyelids and mouth. I think I ruined my skin’s moisture barrier with my love affair with baking soda. Now, I don’t know what to do. The skin on my forehead is so damaged – it flares (itchy, inflamed, bumpy), then weeps, and finally scales. Then it seems to do the entire process over again. I need help restoring my skin to health, but after going from doctor to doctor, in not finding it. Only through your article am I finally putting together the pieces and linking this “seborrheic dermatitis” to baking soda use. My main questions to you: is it safe to brush your teeth with baking soda? Is it safe to wash your armpits and backside with baking soda? I understand now that it’s not safe to wash your face with it. :((((.

  • Deb

    It is not true at all. Baking Soda might be very good for certain skin type. No matter what we use, when we scrub the skin our intention is to remove the top layer of the skin and we have to pay for it – the damage it cause to skin.
    Stupid are those people who are saying something is bad or good for skin. Nothing in this world is particularly good or bad for skin. It is all about maintaining oiliness/dryness of the skin. For example any oil is too bad for oily skin. And soda is very bad for dry skin. It varies from person to person and you have to maintain a balance based on ur own experience. For example in winter my skin become dry so I use moisturiser, but in summer my skin is too oily so I avoid it totally. So it wd be stupid to say moisturiser is good for skin.
    I suggest all to test the product and make decision yourself. Even if many renowned brand claim their product to be good, but it is not true at all. U have to select ur own product. No doctor, no friend, no beauty expert can help u. They can only suggest.

    I just want to leave a comment here so that if they ever get confused, they can at least read comments and “DECIDE FOR THEMSELVES”.
    I made my first homemade face cleaning cream last Christmas and used every weekdays night to remove my make up.
    I use MAC liquid foundation everyday and I know it’s not the healthiest products as most of commercial products contains chemicals that I DON’T KNOW EXACTLY WHAT WILL DO TO MY SKIN, AND UNDERNEATH MY SKIN INTO MY BODY.
    So I am at process to shift my household more natural way.

    The point is that you cannot argue whether “Store-bought” products are better than “homemade” without addressing the definition of “BETTER”.
    I define BETTER as “KNOWING WHAT’S INSIDE” and as long as I feel okay about it, then that’s whole a lot better than store-bought products that contains most of the ingredients I don’t even know.

    At least, I added baking soda to my face cleanser and I used it for 4 months. I have no irritation but I heard it may irritate some people, but it is the same story for store-bought products that state in the back that if you feel any irritation, consult a doctor. So how can one say store-bought is better than home made in this case?

    Finally, I just don’t believe the things that dermatologists or doctors or lawyers or teachers or police or president tell me just because they have those “TITLES”. How many of you know that big corporations (like Monsanto) “BUYS” those scientists and politicians to have it their way, and use advertisement to deceive people like us?

    That is why I like to make my own stuff at home so I don’t have to CONTRIBUTE to those corporations and mainstream trend.
    I hope this helps for anyone who is confused whether to put baking soda in homemade recipe.

    • Canan

      Thank you. You are right, I definitely agree with you…but what is your recipe then?

        Nicki….what? Kanabi I agree with you. I would rather know…including being able to pronounce…what I put in my body as well as on my skin. People are growing tired of being misinformed. Do you own research. What works for you may not work for the next individual and we all can’t afford to be airbrushed. An by the way I used baking soda yesterday to exfoliate and my skin looks great today.

    • wendy jahn

      I totally agree with you. Its all about money with these companies.

    • Ridiculous

      “I DON’T KNOW EXACTLY WHAT WILL DO TO MY SKIN, AND UNDERNEATH MY SKIN INTO MY BODY.” No, you don’t know what those chemicals will do to you. But you probably aren’t a member of the team of chemists and dermatologists that formulate those products. They know exactly what they will do to your skin and your body, and they should–they’re experts. You claim you don’t believe them because they have a “title,” but what they actually have is a degree backed by years of schooling.

      Does that mean every storebought product is perfect? Or every home remedy is harmful? Of course not. If you ever have any questions, consult a dermatologist. They’re absolutely your best resource when it comes to skin care. This goes for products you buy and homemade remedies. You don’t have to read articles or comments online and choose for yourself; you can get an expert opinion from a medical doctor who specializes in skin.

  • Even

    You have an add at the top for Olay and other products…it’s not as if you’re unbiased. Also, why then aren’t you condemning toxic ingredients (or at least cautioning people) found in mainstream hair and facial products?

  • What?

    I was with you up until you said “this is why I highly recommend sticking to professionally formulated products for your beauty routine. It’s not that I don’t love a good home remedy, but I think it’s easy to become misinformed and misuse products”…. Just by saying THIS alone, shows your bias and makes anything you said prior hard to take serious and / or make a well informed decision. HOW can you assume just because a person uses natural / home based products they will be ignorant on how to use ALL home based remedies ???
    Advising on baking soda usage has NOTHING to do with what type of beauty products a person should use or whether they are natural or not. Learn how to leave your bias out of your report / blog next time.

      Hi @What?,

      This is actually a part of a 22-part series on which home remedies work and which do not.

      During that series, we concluded that this home remedy was not all that beneficial, but some were:

      I do apologize for the line that said “This is why I highly recommend sticking to professionally-formulated products for your beauty routine.” In general, what we meant was that it is easy to formulate incorrectly on your own.

      Hope this helps,

    Why is my skin behaving now ever since I been using baking soda. Idk about you but it’s been a while and I am not gonna let a little research throw me off. I honestly think it depends on your skin. Everyone is different.

    • Nicki Zevola

      @Drue – It could also depend on how often and how much you are using.

      • dar

        so this article makes no sense with the response you just provided. that means using baking soda on your skin is not bad at all,.

  • Mary

    I couldn’t read the complete article you used to prove that alkaline cleansers are bad for skin. In the abstract however I read that this was a study on the effects on infants, since there ‘are already many available studies on the effects on adult skin’ .
    Furthermore, the only thing the abstract stated was that alkaline cleansers remove more grease. It also stated that every cleansing agent can affect the skin and make it dry.

    I think it’s suspicious that you used an article that wasn’t written for this purpose (infant skin is way more sensitive) and that you appear to have exaggerated what it stated.

  • I just used baking soda and water to exfoliate my skin and body…is there anything I can do to fix and heal my skin and balance the pH again?

    • Nicki Zevola

      Hi @Yuki –

      Naturally, the skin will reset itself after some time, probably 12-14 hours.

      If you are experiencing redness and irritation, going to the far end of the spectrum and attempting to “neutralize” the effects with acid may cause exfoliation and hence more irritation.

      I wouldn’t worry too much about it. Just stay away from this home remedy in general, is my opinion!

      All the best,

  • Yuki

    I just used baking soda and water to exfoliate my face and body. Now that I know I just damaged my skin, pretty bummed. Is there anything I can do to help my skin heal and balance the pH again?

  • Yuki

    Ermm…I recently just used baking soda mixture with water on my face and body…how long will it take to heal the skin? I wish I ran into this post before I got my hands on the baking soda. Is there anything I can do to heal my skin?

    • jueru

      Are there any visible side effects? I too have been using baking soda recently for atleast once a week and I have no problems with it. I don’t use it with acidic products. And I apply a moisturizer that is also quite antibacterial afterwards and it absorbs really well and my skin looked more flawless than ever. This article feels a bit lacking too. Anyways, I don’t think it is bad to use baking soda because more commercial products are much damaging we just need to take extra precautions and baking soda isn’t to be used everyday. And about exfoliating dont scrub too hard. Personally, I just leave it on the skin for a few minutes(not scrub).

    This may be a little off-topic but considering the science you have shared, is there also risks to brushing your teeth with baking soda?

    I think you forget that the vast majority of soaps are alkaline, with the exception of specialty soaps. Frankly, I use baking soda once, sometimes twice a week to exfoliate. I use it mixed with coconut oil. Daily I cleanse with honey. I still have some blemishes, but my skin has vastly improved and looks far better than when using dermatologist recommended products. I also use various toners, sometimes green tea, sometimes witch hazel + apple cider vinegar, and sometimes a blend using aloe vera gel. The key is knowing your skin and know what works best with your skin.

  • pascale

    I am also a fan of baking soda and like to use simple natural products like apple cider vinegar, vitamin e and coconut oil. Would you have another solution than the store bought solution to suggest? What do you think of sugar? Sugar mixed with coconut oil?

  • Beth

    I’ve used baking soda mixed with tea tree oil soap followed by a diluted solution of apple cider vinegar. My skin type is oily and since I started using this skin care routine my skin has looked amazing. The only time it gets irritated it when I don’t dilute the apple cider vinegar enough with water. Shouldn’t skin type be a contributing factor? Don’t use these ingredients if you have normal/dry skin?

  • Just me

    well, this article fails to address that almost all soaps, shampoos, and skin cleanser except some specialty ones, are in fact alkaline. do the litmus paper test, you shall see.

    • Exactly what I was thinking. It’s so stupid to debunk the benefits of baking soda without comparison to soaps in the market

  • Before you get to alarmist about ph levels of baking soda and its effects on your skin remember that the ocean is around 8. After a day if diving or surfing it can feel a little drying but overall doesn’t seem to be all that damaging to swimmers. Is skin is tougher that you give it credit for?
    Your article briefly mentions amphoteric molecules but quickly returns to acids and bases being the issue. I am still unclear where the risk in using baking soda is.

  • Jen

    I just used a baking soda and water mixture to make a paste for spot treatment. I left it on for 15 minutes and washed off. I’m a bit confused because I saw so many positive reviews on it, and now after I use it, I find a negative. 🙁 What exactly will using it once do?

  • Ive been doing a lot of research on this and I’m now frustrated and confused on this issue. There seems to be two camps of people one half that for whatever reason is in favor of processed and chemical products and has an obvious bias against natural/diy recipes. The other half are also just as ignorant as the former and grab onto this with no research or because at first glance its natural and leave it at that. I am not satisfied with either side. This article seems to be the most coherent but it still doesnt address one thing in my mind. Why wouldn’t you use baking soda as an exfoliant but make sure you follow up with an acid restoration. the same premise as with the “no poo” method. no one under that method only washes with baking soda its imperative to follow up with an acid rinse. quality ingredients aside i dont see this addressed ANYWHERE. all i see is DONT DO IT ITS ALKALiNE, but so? with chemical peels or manual exfiolation it is intentional and controlled injury to get a certain result. even if used sparingly why wouldn’t one be able to use baking soda follower by a diluted acid?? thanks

    • Heh

      You shouldn’t use baking soda and then follow up with acid because the damage is already done. What you’re suggesting is akin to cutting yourself, and then thinking because you put a bandaid on it the cut will immediately heal itself and disappear. That’s not how it works.

      Using baking soda plus an acid is just damaging your skin, and then applying a “bandaid” but still having to wait for it to heal. If you are doing this too frequently, it probably never fully heals and at some point down the road you end up with dry, irritated skin. Instead you could just use a Ph balanced chemical exfoliator that doesn’t damage your skin in the first place, and does a better job of exfoliating.

      • asdfgh

        You skipped the fact that bicarbonate and sodium bicarbonate are different compounds. Before you go all chemistry, please try not separate words like sodium bicarbonate making it into bicarbonate alone. They’re different, REALLY different. It defeats the your statement about alkaline and all those alkali thingy. Just a friendly reminder 🙂

        • Thgthhhg

          Thank you!!

      • Torianna

        If you mix an acid and base such as baking soda and lemon which are in most fit recipies wouldn’t it be considered a neutralized buffer? Making it on average a 5.1 ph, the same average as your natural skin ? I’m no chemist but it seems logical to

        • Lori

          It’s a really bad idea to use baking soda or lemon on your skin, they are both far too harsh and damaging and bring very few positive functions for facial skin. Even if you mix them together, there’s no guarantee that the resulting PH will be suitable unless you litmus test it. Every single time. You can’t just mix random amounts of acid and base and assume they’ve balanced each other out. If you do this you have to be absolutely sure that the PH is balanced but even if it is, there are far safer, more effective ingredients to use on your face than baking soda and lemon. You want to exfoliate naturally, try a konjac sponge. They work beautifully. Ecotools sells a decent one for like $5 and it lasts for about 6 weeks. Korean black sugar wash is also good albeit pricier.
