Acne is a chronic inflammatory disorder that is usually related to hormonal changes, which can stimulate sebum production. Overactive sebaceous glands are usually the cause of adolescent acne. A sebaceous gland produces sebum and there is one at the base of each pore.
Sebum is the main component of pustules (pimples). 80% of teens get pimples, but only 20% develop acne, and blackheads can be precursors to acne.
