What is acne? ...

The most common form of acne is known as ‘Acne Vulgaris’ (meaning ‘common acne’) and this occurs when excessive secretions of oils from the glands combine with naturally occurring dead skin cells to block the hair follicles. Oil secretions build up beneath the blocked pore, providing a perfect environment for skin bacteria to multiply. As a result, the skin becomes inflamed, producing the visible lesion. The face, chest, back, shoulders and upper arms are the most often affected areas.

After the spots have subsided, scars may remain.

Aside from scarring, the main effects of acne are psychological, such as reduced self esteem and depression. Acne usually appears during adolescence, which is a period in life when people are particularly vulnerable and socially insecure.
