Acne is skin condition that occurs when your hair follicles become plugged with oil and dead skin. It often causes white heads, blackheads or pimples usually appear on face, forehead, chest, upper back and shoulders. People of all ages can get acne, but it’s most common in teenagers. Genetics plays a role in acne. Stress doesn’t cause acne, but if you have acne already, it may make it worse.
Acne occurs when sebaceous (oil) glands attached to the hair follicles are stimulated at the time of puberty or due to other hormonal changes. The enlarged gland produces more sebum. Excessive sebum can break down cellular walls in the pores, causing bacteria to grow. Rising androgen levels cause the oil glands under the skin to grow.
