- Participants
- 1,710
- Duration
- 12 weeks
- Comparator
- Tretinoin alone, clindamycin alone, vehicle
In patients with moderate-to-severe acne, tretinoin 0.025% / clindamycin 1.2% combination produced greater reductions in total, inflammatory, and non-inflammatory lesion counts than either monotherapy and vehicle over 12 weeks. Trial results do not predict individual outcomes.
