Acne is a skin disease that involves the oil glands found at the base of hair
follicles. These glands come to life during puberty due to both male and
female hormones produced at that time. Because of these hormones, this
is the time acne usually occurs. Acne occurs when the oil glands at the
base of hair follicles get blocked and oil accumulates under the skin.

Acne isn’t medically dangerous, but it can be frustrating and embarrassing,
especially for teens. It is estimated that nearly ¾ of the population between
11 and 30 will get acne. When acne flares up, it usually occurs on the face,
but often can be found on the back, chest, shoulders and neck.

Research shows that susceptibility to get acne may be genetic. If the child’s
mother had acne, then the child is likely to have it. There are also
medications that may cause acne, mainly those that contain androgen and
lithium. If you’re susceptible to acne, using greasy cosmetics can cause it
to flare up. During pregnancy, hormone changes may cause acne to either
develop for the first time, or to recur if you had it in the past.
