Infantile acne generally affects the cheeks, and sometimes the forehead and chin. It is more common in boys and is usually mild. In most children it settles down within a few months. However, in most babies with acne, no investigations are necessary. Individuals with severe infantile acne tend to develop troublesome acne vulgaris at puberty.
Treatment is usually with topical agents such as benzoyl peroxide or erythromycin gel.
Sometimes, oral antibiotics such as erythromycin, or isotretinoin may be required. New Zealand Dermatological Society.
