In a phase 3, 12-week, randomized, vehicle-controlled study comparing adapalene gel, 0.3%, adapalene gel, 0.1%, and gel vehicle in the treatment of acne vulgaris (N=653), the incidence of scaling, dryness, and stinging/burning was noted early in the study, but signs and symptoms of skin irritation were transient in duration, peaking during the first weeks and decreasing over time. Signs and symptoms of skin irritation were mostly mild or moderate in severity. Few patients experienced severe erythema (0.4% vs 0.8% for adapalene gel, 0.3% and adapalene gel, 0.1% respectively), scaling (1.2% vs 1.6%), dryness (0.8% vs 2.7%), or stinging/burning (3.6% vs 3.9%), with comparable incidence in the adapalene gel, 0.3% and adapalene gel, 0.1% treatment groups.3
