Can this product inactivate Retinol when used together?
I have read that certain ingredients like AHAs (glyolic and lactic acid), BHAs (salicylic acid), ascorbic acid (the acidic form of Vitamin C), and benzoyl peroxide can inactivate Retinol. The 2 ingredients in the Clarins cream I am concerned about effecting the Retinol are the Kiwi Extract and the Sorbic Acid. I am trying to figure out how to incorporate retinol into my nightly process (just started to use PTR Retinol Fusion PM) but I love this night cream so I would hate to give it up! Thanks!

I use this every 3rd night with my Philosophy Retinol caplets. I have not noticed a problem. I do not have sensitive skin and I am 41 yrs old. I hope that helps.

I'm putting on a serum first, waiting about 5 min. then applying this. I have noticed my skin is looking a lot better, but I've been doing this about 3 months, just now seeing some real changes. I weekly use a retinol based, let it sink in for 5 min. then apply this crème.
