Acne is a very common skin condition thought to affect 80% of 11 to 30 year olds, although to varying degrees. Acne can also continue into late adulthood, with some people not having their first flare-up until later in life.
Acne is a caused by an overproduction of sebum which becomes blocked sebaceous glands and creates pimples (blackhead, whiteheads and pustules), which become inflamed. It can also flare up due to hormones, stress and environmental factors.
In order to treat acne you should treat your skin gently, use a foaming or gel cleanser twice a day, and dry with a clean towel each time, as this will prevent bacteria spreading, ensure you pat the skin dry instead of rubbing it. Use a non-astringent clarifying toner to tighten the pores, followed by a light weight moisturiser. If the skin is inflamed, and the spots are weeping then do not exfoliate as this will also spread bacteria, instead use a clay mask twice a week to draw the impurities to the surface.
