La Roche-Posay Effaclar Duo ($36.95) is formulated with Micronized Benzoyl Peroxide [5.5%] to reduce acne and Micro-exfoliating LHA [0.4%] to exfoliate and even out skin texture. It is pricier than the option above, but it did clear up my tween’s severe acne in a matter of two to three days. She does use it daily and I feel it’s mild enough that it won’t irritate her skin. I used it too and it zapped an adult zit overnight.
FOR ADULTS ONLY
Obagi CLENZIderm M.D. System is recommended for adult acne. Benzoyl peroxide and salicylic acid make it a no-no for pregnant women, but all others may benefit from its effective acne-fighting properties. When I was 28 I had a case of androgynous acne, which required hormonal treatment and … I wish I had this to fall back on then!
