Unless under the direction of a dermatologist, avoid using facial scrubs if you have acne-prone skin. Scrubs and abrasives are not effective on pimples and can irritate acne and can actually promote, instead of prevent, flare-ups. To manage acne flareups, try using a three-step acne treatment system with salicylic acid—cleanser, toner, and moisturizer—to help clear up acne and prevent breakout cycles.
