It can be a slimy nuisance when you’re swimming—or a delicious snack!—and now seaweed is the latest skincare star. “It’s loaded with vitamins, minerals, antioxidants, and essential fatty acids,” says Chris G. Adigun, M.D., a dermatologist at Dermatology & Laser Center of Chapel Hill in North Carolina. And it has benefits for all skin types: “Seaweed can help the outer layer of skin stay strong and healthy so it can keep out irritants, its antioxidants protect skin from damage, and it can calm inflammation,” says Ava Shamban, M.D., a dermatologist and the founder of SkinFive Clinics and Ava MD Dermatology in Los Angeles.
TO USE IT:
Face: If your skin is dry, red, or irritated, try incorporating skincare products that contain seaweed, kelp, algae, or their extracts into your regimen twice daily.
Body: Take a 10-minute bath a few times per week with a soak that contains seaweed to relieve eczema symptoms such as itchiness, Dr. Shamban recommends.
