Do AHAs increase skin thickness??
Hi everyone, my question is basically what the title says. But, to give a little more context, I've heard multiple times now through watching various skincare YouTube channels that AHAs can increase the skin's thickness and help promote collagen production. However, I've also read online that AHAs can thin the skin because they speed up cell turnover. I'm confused about which one is true or if both is true. So for those of you who are dermatologists, estheticians, or extensively read studies on things like this, which one have you found to be true?
