Acne is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells. It is characterized by whiteheads, blackheads or pimples, oily skin, and possible scarring. Acne is most common in teenagers, though it affects people of all ages. It affects areas of skin with a large number of oil glands like face, upper part of the chest, shoulders, and back. The resulting appearance can lead to anxiety, reduced self-esteem and in extreme cases depression.
What causes acne?
Normally, dead skin cells come up to the surface of your skin and exit through the pore of hair follicles. In acne, increased production of oily sebum causes the dead skin cells to stick together. The accumulation of dead skin cell debris and oily sebum blocks the pore of hair follicles and causes acne.
The main hormone responsible for oily sebum production is dihydrotestosterone. Higher amounts of hormones are secreted during stages of puberty and leads to an increase in sebum production thereby causing acne during menstruation.
