DEPUFF YOUR EYES
Caffeine is dehydrating -- but when it comes to skin, that can be a good thing! Siphoning excess fluid can smooth out puffy eyes and temporarily reduce the appearance of cellulite, says dermatologist Katie Rodan, MD. Try Pacifica Kona Coffee & Sugar Detox Whole Body Scrub ($28, sephora.com) and 100% Pure Organic Coffee Bean Caffeine Eye Cream ($19, drugstore.com).
WARD OFF AGING
Research shows that caffeine's ability to fend off free radicals triggered by UV exposure gives you antiaging benefits. But while sipping a cup of joe can boost the power of sunscreen, it provides no sun protection on its own. Try caffeine-spiked SkinMedica Daily Physical Defense Sunscreen SPF 30+ ($45, skinmedica.com for stores).
Caffeine is a vasoconstrictor; that's a fancy way of saying it can shrink blood vessels and send ruddy splotches packing, says Dr. Rodan. It also acts like an ice pack, tamping down inflammation and redness. Try Glo Minerals Redness Relief Powder ($26, gloprofessional.com) and Bobbi Brown Hydrating Face Cream ($52, nordstrom.com).
