حمض الساليسيليك

Salicylic acid is a BHA  and unlike other exfoliating acids, it's oil-soluble, which means it gets inside pores to dissolve the sebum and dead cells that cause blackheads and breakouts. That makes it the acid of choice for oily, congested and acne-prone skin. Use 2–3 times weekly to start; it can be drying if overused. Best at night. Ideal for Oily Skin, Pores and Acne & Breakouts.
