"One of my favourites is the La Roche-Posay Effaclar Duo Unifiant (£13). It combines micronised benzoyl peroxide with lipohydroxy acid (LHA) to zap the bacteria that causes acne, exfoliate cell by cell, and renew skin. This treatment is particularly effective because the benzoyl peroxide is formulated into smaller particles to go more deeply into the skin. In addition, LHA is actually derived from salicylic acid but has a slower penetration so it's more gentle." — dermatologist Nikki Tang, MD
"For mild acne I love Effeclar Duo Tinted. It has 2% salicylic acid to combat mild breakouts, and the mild tinted colour works like a CC cream to neutralise any imperfections." — Dr. Schachter
