There are newer companies launching salicylic acid products mixed with retinol that are stable and eqaully active in the skin. What Leslie talks about above was quite a while ago.

[...] existing signs of aging would be better off investing in proven ingredients like retinoids, AHAs (although never together with retinoids, as they inactivate one another due to differing optimal pH levels), and, of course, targeted [...]

First off, great blog…very informative!

My nightly routine is cleanse, tone, serum, vitamin K spot treatment and moisturize my skin every night, religiously. I use Jason Vitamin K on my cheeks and under eye areas and it have helped my broken capillaries and dark circle considerably…love it! Btw, you can visit my blog for review on this (beautifulcanvas.blogspot.com). Anyway, I want to add Vitamin A eye cream to address the lines under my eyes. I feel like this is a lot of layering…something gotta give. Should I drop serum when I use retinols OR keep the serum and alternate between the Jason Vitamin K and retinols?

I use Retin A every night and I use a AHA/BHA exfoliating cleanser about 2-3 times a week in the morning. Is this okay or is it diminishing the effects of both the Retin-A and the exfoliater? Thanks!

Great info but there is so much contradictory stuff out there. My derm actually tells me it’s ok to use my Retin-A with the AHA cleanser he’s recommended. I even asked him about my research about diminished effect when using together and he just scoffed and said it wasn’t true. I prefer not to use them together because my skin can’t take them both- yet!

To answer the question about Salicylic acid and Benzoyl Peroside. Yes you can use them together in the morning. For example, the Obagi Clenziderm normal/oily skin kit has them in together which is what i use.

Thank you for this post! I have been using a toner with salicylic acid every morning and evening. At night, I alternate between a 5% benzoyl peroxide gel and Differin 0.1% gel. Now, I know that I should use Differin all by itself at night. Can I still use salicylic acid and benzoyl peroxide at the same time? Thank you again!

THANK YOU! I can stop searching! Finally some solid advice on how best to use these two treatments in a regular skincare routine. I have read lots of info (on various sites) on why not to use them together but until now I have been unable to find any info on how to use them both in a regular routine. Very much appreciated.
