Salicylic acid minimizes complexion concerns like acne, psoriasis, keratosis pilaris and rosacea while addressing common concerns like enlarged pores, oiliness and blackheads without drying out your skin. A beta hydroxy acid (BHA) derived from willowbark, salicylic acid works its magic by increasing the cellular turnover rate. This leads to faster skin renewal and fewer clogged pores. Salicylic acid is also used for cleansing and soothing body blemishes and troublesome ingrown hairs in the delicate bikini and underarm area.
