Cos De BAHA S4 Salicylic Acid BHA 4% Serum is a powerful exfoliating treatment designed to fight acne, blackheads, and clogged pores. With 4% Salicylic Acid (BHA), it penetrates deep into the skin to dissolve excess oil and impurities, reducing breakouts and improving skin texture. Enriched with 2% Niacinamide (Vitamin B3), it soothes irritation, brightens skin, and strengthens the skin barrier. This serum helps achieve clearer, smoother, and healthier-looking skin.
