Does Salicylic Acid Peel percentage vary with Acne conditions?
Doctor Answers 1
Salicylic Acid peel concentrations
-- the sensitivity of the skin being treated in terms of degree of inflammation or dryness, and how intact the skin barrier is,
-- the skin color, and
-- the response to the last treatment, and the concentration used for that treatment.
The reason for treatment, eg. to improve acne, wrinkles, skin tone, or discoloration, is less of a determinant of strength since the goal is to deliver the highest concentration that the patient can tolerate.
I hope this helps!
