Acne is the most common skin condition in the United States. Between 40 and 50 million Americans have it. It occurs at any age, but most sufferers are teenagers and young adults. Research shows four key players are involved in its formation: excess oil, clogged pores, bacteria and inflammation. The excess oil is sebum which our bodies make to prevent the skin from drying out. Sebum increases dramatically during adolescence when hormones known as androgens spur sebum production into overdrive. If excess sebum cannot flow freely to the skin’s surface, clogged pores result. P. acnes, a bacteria found on everyone’s skin, flourishes in the excess oil and results in inflammation.
Scars (permanent): People who get acne cysts and nodules often see scars when the acne clears. You can prevent these scars. Be sure to see a dermatologist for treatment if you get acne early — between 8 and 12 years old. If someone in your family had acne cysts and nodules, you also should see a dermatologist if you get acne. Treating acne before cysts and nodules appear can prevent scars.
