Reducing your sugar intake is a common fix, but cutting soda out of your diet, in particular, will work wonders for your skin.
Dr. Harold Lancer, dermatologist to Kim Kardashian, Beyoncé, and more explained how sugar affects the skin in his book,"Younger: The Breakthrough Anti-Aging Method for Radiant Skin." According to Dr. Lancer, sugar is a dehydrating agent, so it increases oil production. It also affects water binding so your skin looks less perky and bouncy, and doesn't appear as oxygenated. "The skin becomes sallow, lackluster and you get those unwanted dark circles," he added.
Not only are you limiting excessive sugar consumption by cutting out soda — a single 12 oz. can of Coke contains 39 grams of sugar alone, nearly 80% of the daily recommended intake — but you will also drink healthier alternatives as a result.
