Erythromycin ophthalmic ointment is used clinically for acne treatment and can be effective for the more obvious inflammation, but this ointment has very limited effect on real acne. If the patient has visible acne on the face, he or she can use erythromycin ointment instead of erythromycin ophthalmic ointment, which is not as effective as erythromycin ointment for acne treatment, or fusidic acid cream and mupirocin cream, but mainly for the treatment of inflammatory reactions. If the inflammatory reaction is not too obvious, the use of this ointment still does not work, such as the emergence of obvious keratinization phenomenon, you can apply topical salicylic acid ointment or topical peroxybenzoyl gel treatment.
