Layering Vitamin C and Peptides = One Fancy, Ineffective Cocktail for Skin

Dear Allure magazine,
I appreciate that you're (usually) on the cutting edge of skin care reporting, and (usually) get things right, like talking about stabilizing avobenzone with octocrylene in sunscreens back before even Paula Begoun said a word about it.

But this month's big Pile it On article, all about layering skin care products, fails to mention a common mixture that should be avoided: ascorbic acid and peptides. Don't use them at the same time, or the ascorbic acid destabilizes/cancels out the effects of the peptides. They fight each other. So you'd be wasting a whole lot of $$ on fancy, effective products but not seeing one bit of improvement in your skin.Using one in the morning and the other at night? You might get around this issue.

Oh Allure, I know you're better than this. You even included a section in the article, Dangerous Liaisons, where you discuss not combining certain types of products (AHA/BHA and retinoids, benzoyl peroxide and retinoids, vitamin c and AHA/BHA) without mentioning that vitamin C acts as an AHA. You were almost there!

In the future, keep this in mind. That's all I ask.

Chin up.

Best,
me
