Acne is a combined term that is used to describe a number of skin conditions, like blackheads, blemishes, lumps, and whiteheads. Teenagers and adults can have acne. Stress, hormonal activity, bacteria, steroids, and overactive glands can cause acne.
When we think of acne, the picture that comes to our minds is that of an adolescent, who is physically changing from a child into an adult. However, acne is not restricted to juveniles only. Both adult and juvenile acne are infections generated by the same bacteria.
