What Doctors know - The Facts
Acne develops when excessive amounts of Sebum (oil that lubricates the hair and skin) block the pore. The hair follicle then is infected with bacteria and either whiteheads, blackheads, pimples or cysts are formed.
Acne is more common amongst teens going through puberty because of an imbalance of certain hormones such as androgens (male sex hormone). Androgens are present in both males and females. It is the imbalance of these hormones that triggers the Sebaceous glands (the gland that produces Sebum) into producing an excessive amount of oil.
All other explanations for causes of acne are theories and although many seem logically sound, they are not yet supported by conclusive evidence.
