Chloramphenicol (Clorin) is an antibiotic that is used to treat a wide range of bacterial infections. Chloramphenicol is used as a topical treatment for bacterial conjunctivitis (eye infections).

Chloramphenicol is generally used as a topical treatment for acne. Oral Chloramphenicol is rarely used to treat acne. Laboratory research suggests that the acne causing P. acnes bacteria is moderately susceptible to chloramphenicol. User reports suggest that topical chloramphenicol may be a useful acne treatment.
