Acne is a very common skin condition characterised by comedones, papules and pustules (blackheads, white heads and pus-filled spots). It usually starts in puberty but can also occasionally persist and even suddenly become a problem for men and women in later years.
Acne is caused by excess oil being produced in the sebaceous glands and dead skin cells not being able to shed properly. The bacterium that causes acne lives on everybody’s skin, not normally causing a problem, but with problematic prone skin it is an ideal environment for this bacterium to multiply. This triggers inflammation and the formation of red and pus-filled spots. Most common areas prone to acne are the face, the chest and the back.
