BHA Salicylic Acid 4% Exfoliant Serum with Niacinamide

A high-strength exfoliant serum featuring 4% salicylic acid and niacinamide in an aloe-based formula to clear congestion and refine texture. While most BHA treatments stop at 2%, this one doubles down on potency, making it a serious contender for stubborn blackheads and persistent oiliness. It’s a powerful tool, so treat it with respect—start slow and skip your other actives on the nights you reach for this.
