If the idea of using eye cream sounds too girly, suck it up! Men are jumping on the bandwagon and stocking their medicine cabinets with grooming products—in fact, sales of eye creams for men have gone up 16 percent this year, reports The NPD Group, a market research firm. There is no shame in starting a routine to protect your good looks. “The first obvious signs of aging are the fine lines around the eyes,” says Michael Bruggeman, founder of natural skin care line, Organic Male OM4. Since the skin under the eyes is very thin it's easily susceptible to the damages of stress, late nights and hangovers. To stave off dark circles, puffiness, and old-man bags look for products with natural ingredients like soothing cucumber, inflammation-reducing fennel and brightening bearberry. Vitamin K is especially great for dark circles, which are technically mini bruises, because it helps regulate coagulation. Try Organic Male OM4 Radical Fine Line Eraser Eye Gel, $60; om4men.com.
