I have very oily skin with enlarged pores, blackheads, and moderate acne. I currently control the acne and blackheads with an antibacterial facewash (containing Triclosan), twice-daily application of a 2% BHA exfoliant (pH 3.2-3.6) and nightly application of 2.5% Benzoyl Peroxide. I am considering undergoing a course of low dose Accutane (0.15mg/kg/day) to reduce oil production and control my acne. Is continued usage of my BHA permissable for general exfoliation purposes?
