 Products containing sulfacetamide and sulfur (a keratolytic) are commonly promoted for the treatment of acne rosacea (rosacea with papules, pustules, or both).There are several prescription topical products containing sulfacetamide, such as foams, shampoos, cream and washes.Some research indicates that sulfacetamide derivatives may act as antifungals by an CYP51A1-independent mechanism.
