I’m interested in a post about all the eyelash serums out now especially the over the counter ones like Revitalash, Rapid Lash etc. Are they safe? What’s the difference between them?
Eyelash growth serums generally contain either a prostaglandin derivative, like prescription Latisse, or over-the-counter Revitalash; peptides, like Jan Marini Growth Serum; or vitamins, like Peter Thomas Roth Lashes to Die For. In general, prescription-strength prostaglandins are the most effective, whereas I personally do not recommend vitamin-only serums, which have never been of any use to me.[Read more: Do Hair Growth Supplements Really Work?]
I detail each of these below:
Most Likely to Work #1: Latisse
Latisse is a prescription-only treatment formulated with a prostaglanoid called bimatoprost. In a number of reputable studies, bimatoprost has been proven to increase eyelash growth. In one published FDA-reviewed clinical trial, approximately 140 volunteers’ eyelashes typically grew 25 percent longer, 106 percent thicker and 18 percent darker with Latisse (bimatoprost) than those in the non-treatment (control) group.
Although many women are fearful of Latisse due to the possible side effects, only 3.6 percent of patients in the Allergan study experienced eye itching and red eyes, and none had a change of eye color. Still, this does not mean this product is entirely without risk. As Dr. Howard Kaplan, M.D. reports to the New York Times, “A change in eye color is a potential side effect of using Latisse, though it is not a common one. Because it’s possible for this side effect to occur, it’s important to weigh the potential risks and benefits of using the product with your physician.” Indeed, any change in eye color that occurs is likely to be permanent, particularly if you have light-colored eyes.
Other potential risks include a very slight increased risk of glaucoma, although the FDA designated the active ingredient in Latisse (lumigan, a prostaglandin analog) as perfectly safe and unlikely to cause glaucoma (Expert Opinion on Drug Safety).
Ingredients in Latisse: Active ingredient: bimatoprost; Inactrive ingredients:benzalkonium chloride; sodium chloride; sodium phosphate, dibasic; citric acid; andpurified water. Sodium hydroxide and/or hydrochloric acid may be added to adjust pH. The pH during its shelf life ranges from 6.8 – 7.8.
Most Likely to Work #2: Revitalash
Once upon a time, before Allergan requested FDA investigate the use of prostaglanoids in a prescription strength for eyelash growth, there was a milder prostaglanoid called latanoprost in an over-the-counter product called Revitalash ($60, Amazon.com). Though Revitalash had its risks, it was deemed low enough in latanoprost to remain available without a prescription.
Today Revitalash continues to sell well, though a prescription-strength formula is available for $30 more/month. The risks with Revitalash are the same as Latisse, due to its containing the prostaglanoids latanoprost: namely, a very slight risk of increased intraocular pressure (i.e., glaucoma) and a change in eye color.
The latanoprost in Revitalash works in the same fashion as the bimatoprost in Latisse, as both are prostaglandin derivates. However, because the active ingredient in Revitalash is low enough in concentration to not require a prescription, Revitalash is likely to be slightly safer and less effective than Latisse. I think of Revitalash as training wheels for anyone who is considering Latisse. At any rate, be sure to ask your physician before using Revitalash.
Ingredients in Revitalash: Purified Deionized Water, Sodium Chloride, Panthenol (Provitamin B-5), Citric Acid, Phenoxyethanol, Chlorphenesin, Disodium Phosphate, (Z)-7-[(1R,2R,3R,5S)-3,5-Dihydroxy-2-(R,E)-3-hydroxy-4(3- trifluoromethyl)phenoxy)but-1-enyl)cyclopentyl]-5-Nethylheptenamide, Cellulose Gum
Most Likely to Work #3: Jan Marini Eyelash Conditioner
For those who are concerned about changing their eye color or contracting glaucoma, Marini Lash ($125, Amazon.com) provides a prostaglandin-free alternative. Though Marini Lash contained latanoprost until 2008, it was later removed from the products due to consumer safety concerns. Jan Marini, president and CEO of Jan Marini Skin Research, sums up the reformulated eyelash serum: “With Marini Lash, anyone can have thicker and lusher-appearing lashes without the substantial cost or warning labels that accompany the Latisse prescription product…Neither Marini Lash nor its companion product, Marini Mascara™ Performance Mascara, contain the glaucoma drug in Latisse…”(PR Newswire)
Instead, the active ingredients in Marini Lash are the peptides, which are believed to stimulate hair growth at the follicle, according to Dermatologic Clinics. Myristoyl Pentapeptide-17 and Myristoyl Pentapeptide-12, the peptides in Marini Lash, have not specifically been documented to stimulate hair growth in any peer-reviewed, published, independent studies. However, reported in-house studies at Jan Marini Skin Research, Inc. document that these peptides are effective.
Despite the lack of mention of Myristoyl Pentapeptide-17 and Myristoyl Pentapeptide-12 in peer-reviewed scientific journals, I still like Marini Lash. After the company sent me a vial of this product, I used it nightly for four weeks. My lashes grew about 20-25% longer! Other bloggers also provide glowing reviews, like Beauty Girl Musings (with impressive photos) and The Wall Street Journal Health Blog, although some reviewers do not note a change.
Ingredients in Marini Lash (2008 – present): Water (Aqua), Sodium Hyaluronate, Hydrolyzed Glycosaminoglycans, Diazolidinyl Urea, Methylparaben, Proplyparaben, C12-C15 Alkyl Benzoate, Panthenol, Acrylates/C10-C30 Alkyl Acrylate Crosspolymer, Myristoyl Pentapeptide-17, Myristoyl Tetrapeptide-12, Linoleic Acid, Linolenic Acid, Tocopherol, Biotin, Camellia Sinensis (White Tea) Leaf Extract, Aesculus Hippocastanum (Horse Chestnut) Seed Extract, Cinnamomum Zeylanicum (Cinnamon) Bark Extract, Butylene Glycol, Saccharomyces/Copper Ferment, Sodium Phosphate Dibasic, Sodium Chloride, Triethanolamine, Vitamin B-12, Folic Acid
Most Likely to Work #4: Peter Thomas Roth Lashes To Die For
The secret to Peter Thomas Roth Lashes to Die For ($72.50, Amazon.com)? Vitamins, namely A, C, E, and Pro-Vitamin B5. Yet I’m not ecstatic about the use of vitamins to stimulate hair growth, and I’m not the only one reluctant to jump on the bandwagon. According to a review in Chemical and Physical Behavior of Human Hair, “much remains to be discovered about growth factors such as vitamins … and their effects on hair growth and development.”
In four to eight week independent consumer studies of Peter Thomas Roth Lashes to Die For, lashes appeared softer in 80%, fuller in 67%, and enhanced overall in 70% of cases. However, marks of approval from consumer studies fail to impress me as much as actual measurements of growth, as approximately 1/3 of consumers will report a positive effect even when using a placebo.
Customer reviews of the product appear to be mixed. While some have had positive experiences, like fellow blogger Nancy at Beauty411, others do not experience any effect in growth at all. (Overall: about 60% positive reviews). I personally would be interested to see if consumers that exhibit eyelash growth also take a multi-vitamin. It would be my guess that maximal effect of this product would take place in patients who have some sort of a vitamin deficiency — but then again, until we better understand the role of vitamins in hair growth physiology, who knows?
Ingredients in Peter Thomas Roth Lashes to Die For: Water, Aloe Barbadensis Leaf Juice, Panthenol, Retinyl Palmitate, Ascorbyl Palmitate, Tocopheryl Acetate, Phospholipids, Sodium Hyaluronate, Hydrolyzed Glycosaminoglycans, Glycerin, Propylene Glycol, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, C12-15 Alkyl Benzoate Cyclodextrin N-[2-Hydroxy-1-Hydroxymethyl)Ethyl]-9-Oxo-11.Alpha.,15s-Dihydroxy-17-Phenyl-18,19,20-Trinor-Prosta-5z,13e-Dien-1-Amide, Triethanolamine, Leuconostoc/Radish Root Ferment Filtrate, Alcohol.
Most Likely to Work #5: Enormous Lash
Enormous Lash ($95.00, Amazon.com) used to contain prostaglandins, but has since been reformulated to contain vitamin B5 (like Peter Thomas Roth Lashes to Die For) and peptides (like Marini Lash, although different peptides).
As with the rest of the non-prostaglandin eyelash growth serums, the reviews remain to be mixed of Enormous Lash (about 60% positive reviews) with many of the positive reviews having been conducted before the product was reformulated. Still, there is something to be said for a product with both peptides and vitamins, and even though the research behind this specific formulation is limited, it may be worth a try, particularly if you are afraid of using products containing prostaglandins.
Ingredients in Enormous Lash: Water, Butylene Glycol, Glycerine, Potassium Olivoyl PCA, Arginine, Alanyk Glutamine, Saccharomyces/Copper Ferment, Phospholipids, Sphingolipids, Panthenol, Caprylyl Glycol, Phenoxyethanol, Isopentyl glycol, Hydroxyethylcellulose, Trisoium EDTA.
The Bottom Line
No matter which eyelash serum you choose, your lashes will grow only to their previous length when you discontinue use of the product. With that said, you can always try different products and experiment which works best for you in a timespan of 1-2 months.[Read more: Does Rimmel Lash Accelerator Mascara with Lash-Grow Complex Work?]
The truth of the matter is, the best eyelash growth serum appears to be a product with prostaglandins. This includes products such as Latisse and Revitalash, seem to be the most likely to increase the growth of your lashes in the shortest amount of time. However, due to the possible risks involved, many choose other excellent eyelash growth serums, such as peptide-rich Marini Lash.[Read more: 5 Steps to the Thickest, Longest Lashes Ever]
The best option is to talk to your physician and/or ophthalmologist about your concerns, and together you can determine if you are a candidate for prostaglandin derivates, or if vitamins or peptides would be a better option for you.
