2. Red Vegetables
Red vegetables are rich in something known as lycopene, an antioxidant that HelloGlow.com says “essentially acts as a natural sunblock and collagen booster.” Tomatoes are one such example, as are fruits like strawberries, watermelon, and pink grapefruit.
In addition to lycopene, red bell peppers also contain plenty of vitamin C, which “…is an antioxidant that promotes collagen synthesis,” explains registered dietician Ashley Barrient in speaking with Prevention.com. A half-cup serving offers 95 milligrams (mg) of the vitamin, which equates to 158 percent of your required daily intake.
