A topical for acne that works on pore blockage, bacteria and inflammation at once, and inhibits tyrosinase to help manage post-inflammatory pigmentation.
Known as a brightening ingredient, but its main place is acne treatment. Not an antibiotic, so it can be used relatively long without resistance concerns.
Safety and efficacy of the 20% cream are not established under age 12. In pregnancy it is among the topicals considered because systemic absorption is low — after consulting a doctor.
