I have adult acne. What is it, why does it happen and how can I get rid of it?
One of the most common skin problems that I see as a dermatologist is acne. It has been estimated to occur in approximately 70 million people. Acne can occur at any age; nearly all teenagers between the ages of 12 and 17 are affected. It may resolve spontaneously or persist into adulthood. There are four major causes of acne:
(1) Excessive oil (sebum) production caused by stimulation from androgens (sex hormones) in the body.
(2) Obstruction of the pores under the skin.
(3) Buildup of bacteria (propionibacterium acnes) in the skin.
(4) Inflammation caused by an increase of white blood cells into the acne lesions.
In adult women, acne can occur due to changing hormones throughout the monthly cycle, with flares occurring before menstruation. Also, oil-containing hairstyling products, cosmetics and moisturizers applied to the skin can clog the pores and cause acne.
One of the major concerns of patients of color who experience acne is the occurrence of dark spots or discoloration. These blemishes are the result of increased pigment (melanin) deposits caused by the inflammation of the skin from acne.
