Mid-childhood acne — 1–6 years of age

Acne in this age group is very rare. An endocrinologist should be consulted to exclude possible hyperandrogenism. 

Preadolescent acne — 7–12 years (or up to menarche if female) 

Acne can be the first sign of puberty, and it is common to find acne in this age group. 

It often presents as comedones in the ‘T-zone’, the region of the face covering the central forehead and the central part of the face (eg, the brow, nose, and lips).
