In a 12-week study of 741 people with moderate-to-severe acne, the triple-combo gel (clindamycin + benzoyl peroxide + adapalene) cleared skin in 52.5% of users versus 8.1% with placebo. It reduced inflammatory spots by about 30 and non-inflammatory ones by about 35, outperforming two-ingredient versions. Side effects were mostly mild to moderate.
Researchers randomly assigned acne patients aged 9+ to either the triple-combo gel, placebo, or three different two-ingredient combinations. They measured success by looking at skin improvement and counting lesions over 12 weeks.
