How to use

Blemish Buster Clear: Use during the day applying a dab to your problem pimple and blemish areas.

Blemish Buster Solution: Clean skin thoroughly before applying. Cover the entire affected area one to three times per day with a thin layer. Because excess drying of the skin may occur, start with one application daily, then gradually increase to two or three times daily if needed or as directed by a doctor. If bothersome drying or peeling occurs, reduce application to once a day or every other day. Best used in the evening.
