Do AHAs increase skin thickness??

Question

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?

Esthetician here, indeed aha helps to remove dead skin cells and show the newest skin cells to the world. AHA has many positive values for the skin and from logical point removing dead skin cells makes your skin thinner but the upper layer of the skin is usually a dead skin anyway - these cells did they work and went from deeper parts of the skin into the surface.
