Acne is a common and frustrating skin ailment that usually affects adolescents or teenagers. It occurs when hair follicles get clogged with oil and dead skin cells. Acne triggers on face, and then may also spread to the upper part of the chest, upper arms, back and bottom.
Some people may experience the severe form of this disorder a little later than adolescence and in some rare cases it may continue up the age of forty. Acne can be very distressing and annoying due to their persistent nature and cause emotional distress to the victims. If not treated properly, they cause visible scars and blemishes on affected skin.
