Many women think of acne as something they bid farewell to with adolescence. But actually, a significant number of women over the age of 25 year experience adult acne. Because you have acne as an adult, it can be frustrating and embarrassing, but rest assured that adult acne is quite common.
Adult acne can be divided into two general types: persistent and late-onset acne.
Persistent acne is acne that continues from adolescence into adulthood. Patients tend to have lesions most days and may experience flare-ups before their menstrual cycles.
Late-onset acne appears for the first time in adulthood and falls into two categories. Chin acne is concentrated in the mouth area and tends to flare premenstrual. Sporadic acne tends to appear and die down suddenly, with no apparent reason.
What causes adult acne? The causes of adult acne are not entirely clear. It may be linked to the behavior of certain sex hormones, particularly those called androgens, which control excretion from the oil-producing sebaceous glands.
Other possible triggers include smoking, cosmetic use, stress or taking certain medications such as those used to treat epilepsy or depression. Some women may also have a genetic predisposition to the condition.
