Can a 20% Salicylic Acid Peel Make Old Faded Acne Scars Reappear?

A 20% Salicylic peel should only be in the hands of a licensed esthetician. The peel is superficial, but alot of pretreatment factors need to be considered before any peel is done.  Asian skin can be very fragile in terms of developing post inflammatory hyperpigmentation.  The darker skin spots may be skin that is ready to peel. In the future, I would reccomend a professional treatment.

Salicylic acid can cause hyper pigmentation on darker colored skin types.  This might be what you are seeing.  It is also possible that, the surface layer of skin was exfoliated (burned essentially), revealing deeper layers where acne scaring is present.  Many times the skin will look darker in patches where the skin has been damaged in the past, these are the areas that are going to peel and flake off the heaviest.

It is always wise to seek a professional skin care treatment from a license esthetician or skin specialist when using products of this intensity.

Salicylic acid peels are not effective in treating acne scars. These peels improve skin texture and color and are most often used to treat acne and sun damaged skin.
