Acne is an extremely prevalent and often distressing chronic skin condition; almost everyone has symptoms at some point in their lives. Those of us who may have escaped acne in their teens may develop persistent adult-onset acne as we get older. Women are more likely than men to have mild to moderate forms of acne into their 30s and beyond. It is characterised by non-inflammatory lesions, blackheads/whiteheads, and inflammatory skin lesions such as cysts and pustules. Acne can result in pitted scarring and depending on the skin type, areas of pigmentation.
