With all the information on acne causes and treatments you read in books, magazines, or on the Internet, it's difficult sometimes to know what is fact and what is myth. You will find home remedies, herbal medicines, creams, gels, vitamins, antibiotics, hormonal treatments, retinoids, laser treatment and the list goes on.

First of all what is acne? Acne (pimples, whiteheads, zits) is the result of hair follicles and skin pores getting clogged when the body produces too much oil which builds up which then leads to swelling, pimples, zits or whiteheads. The oily substance is called sebum which lubricates and moisturizes the skin and hair. Normally, sebum produces small amounts of oil, but sometimes, although no one knows for sure why, starts over-producing oil. Hormones play a part in the amount of sebum that is produced during adolescence. The male hormone androgen, can cause sebaceous glands to enlarge leading to the increase of more sebum.
