Eptex™ Acne Relief Lotion with 2% salicylic acid delivers 4 times more active ingredient than the leading brand. Controlled release technology slowly delivers our unique formulation over time, making it ideal for sensitive skin. It gently exfoliates, removing dead skin cells from the top layer of the skin. Exfoliation deeply cleanses the skin, dislodging buildup in the pores and breaking up whiteheads. It also helps to smooth and refine the skin’s texture.
