Sea Change

Grooming gurus have long used landlocked minerals and vegetation to aid in self-preservation. But don't discount oceans, and the aquatic gardens they house, when it comes to skincare. Underwater foliage, such as algae and seaweed, is surfacing in products with increased frequency (see next page). "It's packed with nutrients like vitamins A, D, and E, along with amino acids," says Margo Marrone, a U.K.'based homeopathic pharmacist and founder of The Organic Pharmacy. She also praises the organisms for their ability to boost microcirculation: "More circulation in your blood vessels helps supply valuable minerals to your cells while simultaneously promoting the elimination of toxins."

And sea plants do more than just expedite the skin's cellular cleansing functions. "Algae promotes the body's ability to produce hyaluronic acid, a naturally occurring chemical responsible for the body's hydration," Marrone says. "It reduces the appearance of wrinkles by plumping your cells with water and doesn't leave a greasy feeling." David Colbert, founder of the New York Dermatology Group, is also onboard. "Algae is a known antioxidant and protects your skin from UV damage," he says. "Some studies show it fights against acne-causing bacteria and also helps with cellular regeneration."
