It is very confusing with so many first cousins around of AHAs, Salicylic Acid, Glycolic Acid, Lactic Acid & Ammonium Lactate.
Which one is the better one of these? I believe all of them essentially do the same job - They help with itching in KP/Eczema/Psoriasis, slough off dead skin, exfoliate, unplug pores, reduce wrinkles.

So how does one choose & in what strenght? They are all available in 1 - 12%. Body wash, lotion, face wash, day lotion & even shaving cream.
I am currently using a 1% Salicylic Acid face wash for my acne & Psoriasis on face & a 12% Glycolic Acid body cream for my psoriasis.
