Acne is not caused by dirt. Testosterone, a hormone which is present in males and females increases during puberty. It stimulates the sebaceous glands to enlarge, produce oil, and plug the pores. Whiteheads, blackheads, and pimples are present in teenage acne. Adult acne develops later in life and may be related to hormones, childbirth, menopause, or stopping the pill.
Cleaning the skin with a mild cleanser and warm water daily is essential. Over washing can cause more oil production. Acne is not caused by foods however, if certain foods make your acne worse, avoid them. Wear as little cosmetics as possible. Use oil-free and water-based moisturizers and make-up. Look for products that say "non-acnegenic" and "non-comedogenic". Light chemical peels with salicylic acid or glycolic acid help to unblock the pores, open the blackheads and whiteheads, and stimulate new skin growth. Microdermabrasion may be used to remove the upper layers of the skin to improve the surface and generate new skin.
