What causes acne?

"Acne can happen to anyone at any age. It is also thought to run in families, which means that you are more likely to have acne if your parents had it in the past."

Acne is a common skin condition that affects most people at some point during their lives. It causes oily skin, redness and spots, which can make your skin red or painful to touch.

Acne happens when the hair follicles in your skin (the little holes that your hairs grow from) get blocked. Hair follicles can get blocked when the sebaceous glands (glands near the surface of your skin) make too much sebum. Sebum is an oil that helps keep your skin moisturised, and stops it from drying out. Too much sebum will block your pores and cause spots.

Acne is most common in teenagers or young adults. Teenage acne is triggered by the increased levels of testosterone in your body when you go through puberty. The change in hormones triggers your sebaceous glands to make more sebum than your skin needs. This causes your follicles to block and produces spots.

Acne can happen to anyone at any age. It is also thought to run in families, which means that you are more likely to have acne if your parents had it in the past.
