Infantile acne

This summary discusses acne in infants. Acne in neonates and acne vulgaris in adults and children are discussed separately.

Acne presenting between 3 and 6 months of age is classified as infantile acne. Some authors consider infantile acne at the lower end of the age spectrum of juvenile acne, which presents at up to 24 months but with a median of 9 months. It is postulated that it is due to hormonal imbalances, an immature adrenal gland with elevated dehydroepiandrosterone (DHEA) and elevated luteinizing hormone (LH), often noted in infant males. Associated endocrine abnormalities and other virilizing signs are usually not seen. Infantile acne usually subsides after 1-2 years, although it may rarely persist into adolescence. Severe nodular forms may leave scars.
