A method of treatment of seborrheic dermatitis includes the application, in the form of either a lotion or a cream, of a mixture including a therapeutically effective amount of ivermectin in water in a concentration of about 750 micrograms per milliliter (mcg/ml), in the case of a lotion, and with a pharmaceutically acceptable carrier if used as a cream. Such a lotion or cream is applied nightly for a period of seven days and then employed on a maintenance basis one to four times per month.
Dermatological conditions/afflictions such as rosacea, common acne, seborrheic dermatitis, perioral dermatitis, acneform rashes, transient acantholytic dermatosis, and acne necrotica miliaris, 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.
