Acne is a skin problem that affects a large number of men and women all over the world. It is particularly common in teenagers, as a result of the increase in hormonal levels due to puberty.
Acne can manifest in a variety of ways including whiteheads, blackheads, papules, pustules, nodules, and cysts. While it is not a serious health problem, acne can make you feel overly conscious about your appearance and lower your self esteem.
