Acne is a common skin condition that causes spots, oily skin, and sometimes skin that is hot or painful to touch. It usually affects the face, back and chest. Most people get acne at some point, especially between the ages of 12 and 25, but it can carry on or start in adulthood.
Types of spots
- blackheads and whiteheads
- papules (small red bumps) and pustules (spots with pus)
- nodules and cysts, which are large, painful lumps under the skin and are more likely to scar
What causes acne?
Acne happens when tiny holes in the skin (hair follicles) get blocked with oil and dead skin cells. It is linked to hormones, and often runs in families. It can flare:
- around periods, in pregnancy, or with polycystic ovary syndrome (PCOS)
- with some medicines or cosmetics
- with sweating, and when things rub against the skin
When to see a GP
See a GP or pharmacist if acne is not improving with pharmacy treatments, is causing scarring, or is affecting how you feel. Get help early for nodules and cysts, as they can leave permanent scars.

Common questions
Is acne caused by a poor diet or not washing?
No. Acne is not caused by being dirty, and there is little evidence that diet is a major cause. Washing too often or scrubbing can make it worse.
Is acne only a problem for teenagers?
No. It is most common in teenagers, but many adults, especially women, have acne too.
