But the side effects of targeted breakout cream treatments aren’t always worth it. “So many products instruct consumers to use benzoyl peroxide spot treat red bumps and pustules. I don’t recommend it,” says Dr. Lawrence Green, board-certified dermatologist and assistant clinical professor of dermatology at George Washington University. Such high concentrations of benzoyl peroxide cause added irritation and inflammation to already sensitive skin, so with this in mind, we cut kits that included spot treatments.
Although acne remains largely a curse of adolescence, about 20% of all cases occur in adults. Acne commonly starts during puberty between the ages of 10 and 13 and tends to be worse in people with oily skin. Teenage acne usually lasts for five to 10 years, normally going away during the early 20s. It occurs in both sexes, although teenage boys tend to have the most severe cases. Women are more likely than men to have mild to moderate forms into their 30s and beyond.
Diet. Studies indicate that certain dietary factors, including skim milk and carbohydrate-rich foods — such as bread, bagels and chips — may worsen acne. Chocolate has long been suspected of making acne worse. A small study of 14 men with acne showed that eating chocolate was related to a worsening of symptoms. Further study is needed to examine why this happens and whether people with acne would benefit from following specific dietary restrictions.
