Also called beta hydroxy acid (BHA), this multifunctional ingredient addresses many of the systemic causes of acne. [1]

It has the ability to penetrate into the pore lining and exfoliate inside the pore as well as on the surface of skin, which makes it effective for reducing breakouts, including blackheads and whiteheads. [2, 3, 4]
