Dermatological conditions/afflictions such as rosacea, common acne, seborrheic dermatitis, perioral dermatitis, acneform rashes, transient acantholytic dermatosis, and acne necrotica milliaris, most notably rosacea, are treated by topically applying onto the affected skin area of an individual in need of such treatment, a topical pharmaceutical composition which comprises a thus effective amount of ivermectin.
