This medication is used to treat several skin problems (acne, acne rosacea, seborrheic dermatitis). Sodium sulfacetamide works by stopping the growth of certain bacteria on the skin that can lead to acne and worsen these other skin conditions. It belongs to a class of drugs known as sulfa antibiotics. Sulfur works by helping remove the top layer of dead skin. It belongs to a class of drugs known as keratolytics. It may also help kill acne-causing bacteria and unclog pores.
This medication may also contain other ingredients (for example, other keratolytics such as urea).
