A regimen is described for the therapeutic treatment of rosacea. The regimen includes topically applying a pharmaceutical composition to the skin of a subject in need of said treatment. The pharmaceutical composition includes from about 2.5% to about 10% benzoyl peroxide as the only active ingredient, and a pharmaceutically acceptable carrier or excipient. The regimen achieves, in a group of such subjects, a primary measure of success of at least about 9%, at least about 25%, at least about 40%, or at least about 47%, after application of said pharmaceutical composition once daily for at least about 2 weeks, at least about 4 weeks, at least about 8 weeks, or at least about 12 weeks, respectively.
