And a retinoid, which we’ve touched on before, is beneficial for exfoliating the skin and purging your pores of dirt and oil, which is why Zeichner says they’re helpful for cysts, too. He recommends Differin, the only prescription-strength retinoid that’s available over the counter, and which many derms here have suggested to us before for acne-prone skin. He says you can use a pea-size amount and start applying it every other night as your skin gets adjusted to it (or combine it with benzoyl peroxide and salicylic acid for a stronger mixture).
Warning: Sulfur smells like rotten eggs. But it is an effective ingredient at drying up pus-filled pimples and whiteheads (you’ve gotta take the good with the bad). It works by sucking up the oil. Sulfur is typically mixed with other active ingredients to get the most efficacy and fragrances to mask the strong scent. You can often find it in masks and 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.
