2. Green tea
Green tea fights acne based on its ability to lower levels of an acne-producing hormone called dihydrotestosterone (DHT), says Logan. He recommends brewing up three to five cups of green tea every day in order to reap the full benefits for your skin.
This power drink is also packed with antioxidants, which will help your skin look younger and healthier overall, says Koo.
Deeply coloured berries such as blueberries and cherries are loaded with antioxidants, which help your body fight off blemishes. “One thing we found out very recently about acne is that there’s a great local oxidative stress going on, so much so that it actually depletes the antioxidants in people with acne. So the more severe your acne, the lower your levels of blood antioxidants,” says Logan.
4. Fish and seafood
An international study published in the Journal of the American College of Nutrition found that people who ate diets high in fish and seafood had less skin wrinkling. That might be because the omega-3 fatty acids found in fish and seafood slow down the wrinkling process. Wrinkle development is rooted in inflammation, says Logan. “Inflammatory chemicals are essentially like acid rain on the collagen of your skin. Omega-3s turn down the dial on the production of these chemicals,” he explains.
Omega-3s can also help combat acne in a similar way. “Acne spots can look red and are often warmer to the touch, a clear sign of inflammation,” says Koo. “Furthermore, omega-3 fatty acids have mood-regulating benefits, which can help with the stress component of having acne.” He recommends that acne sufferers consume four to five servings of oily fish per week in order to treat the condition. If you can’t imagine eating that much fish every week, Koo suggests taking fish oil supplements instead.
