How deep do AHAs exfoliate
If we use 10% lactic acid daily as leave on or 30% lactic acid twice a week for 10 minutes, both at pH 3, how deep will it exfoliant the skin?
I mean does it only exfoliate part of stratum corneum or it can completely exfoliate it or even deeper layers?

hi, I am not a dermatologist but as far as I know, 5 % is safe for Deeper layers of the skin at 10-15 % you will get into the deeper layers of the skin.
it not necessarily has a bad effect but it has an effect on deeper layers. especially for a leaf on.
I would guess that 30 % for 10 min does send feel very nice on the skin. not sure if that is beneficial for Skin Thickness and even skin tone.
I would recommend asking your supplier of the Raw material he can probably tell you about maximum concentrations for leave-on and Rinsof without harming the skin.

@Gordof thanks
I have some information about formulating AHA. I just wanted to know if it will remove stratum corneum completely at any percentage or just different percentages of stratum corneum at 5-30%?
