85% of the population between the ages of 12 and 24 develop acne. It tends to go away in the thirties although some people in their forties and fifties continue to have the disorder. Moderate to severe inflammatory acne can be treated with prescription topical or oral medications alone or in combination. Treatment aims to heal existing lesions, stop new lesions from forming, and to prevent scarring. This also helps to minimize the embarrassment and psychological stress that accompanies a disorder like acne. Early treatment is the best way to prevent acne scars.
