Acne is an inflammatory skin disease that is caused due to certain biological variations in the pilosebaseous units (skin structures consisting of a hair follicle and its connecting sebaceous gland) of the skin. The most common form of acne known as "acne vulgaris" usually appears during adolescence.

Acne is caused due to excessive oil in human body. The glands in the skin secrete excessive amount of oil that block the hair follicles by combining naturally with the dead skin cells. Generally, people who eat a lot of oily food suffer from this problem.

Due to acne some parts of the human body are affected. Some of them are face, arms etc. The oil secretions behind the blocked pores create a perfect environment for uncontrolled multiplication by the bacteria in the skin. In response, the skin inflames, producing the visible lesion (acne). Rashes are occurred on the body. The face, upper arms, back and chest are especially affected by acne.

The certain lesions of acne are: blackish elevations or pale yellow and/or small whitish bumps. More inflamed rashes take the shape of boil-like tender swellings or reddish bumps. After resolution of the blemishes, prominent unsightly acne scars may remain.

The acne condition is common in puberty as a result of an abnormal response to normal levels of the male hormone testosterone. Acne occurs when the hormones are increased due to excess oil in the body. There is however no way to predict how long acne will take to disappear completely or that it will ever recur again.

Acne affects a large percentage of humans at some stage in life. Apart from leaving behind the marks of scars it has some psychological effects as well causing stress and depression. Therefore acne should not be neglected and should be treated with great care and responsibility to ensure a healthy life.
