Flavanols also help improve the look and health of the skin. It reduces stress hormones, which means fewer wrinkles, lines and breakouts. Cocoa flavanols are also antioxidants that help protect the skin from ultraviolet damage from the sun, fight free radicals and increase blood flow. This means even fewer wrinkles, fewer sunspots and a healthy skin glow. Another benefit from the flavanols in dark chocolate is improved hydration and thickness, which promotes healthy and younger-looking skin.
