Can erythromycin ointment treat closed acne

Erythromycin ointment has a certain effect on closed acne, but the effect is limited.

Erythromycin ointment has antibacterial and anti-inflammatory effects. For closed acne caused by bacterial infection, inflammation may be reduced to a certain extent. However, it does not fundamentally solve the causes of closed acne formation, such as excessive sebaceous gland secretion, abnormal hair follicle keratosis, etc.

However, the use of erythromycin ointment alone may not completely eliminate closed acne. The treatment of closed acne often requires a combination of methods, including keeping skin clean, adjusting diet and living habits, using appropriate skin care products, etc. In addition, drugs must be used reasonably under the guidance of a doctor.
