Acne is the most common skin condition with more than 90% of Canadians having been affected at one time or another. It is thought that acne begins at puberty when hormone levels increase and heredity can play a role. Usually acne begins during your teen years and peaks in the late teens, but some people may have acne that persists into their thirties and forties.
The face is most often affected, but the chest and back may also be involved. Acne is an inflammatory condition caused when a waxy substance known as sebum which accumulates and plugs the sebaceous glands resulting in comedones. Comedones can either be open or closed, that is a black head or white head. Comedones can become infected forming a pus-filled cyst or pimple. Sometimes these lesions can be red, swollen, and deep; and after healing leave scars.
Non-prescription acne medications include medicated soaps and skin washes, keratolytics like salicylic acid which help remove comedones, and benzoyl peroxide which has an antibacterial effect. For mild acne, these products used twice daily may be effective. If your acne is extensive or deep, you may need a prescription item. Antibiotics such as erythromycin or tetracycline can be used either applied on the skin or taken orally. They reduce infection and help control inflammation. Vitamin A or retinoid compounds are applied to acne, however initially you may experience more redness and irritation. Oral isotretinoin is available, but can cause birth defects. Hormonal agents which counteract androgen’s effects are also an option for females affected by acne.
