Slathering yourself from head to toe in seaweed may sound like a dare you contemplated accepting while spending a day by the ocean as a kid. But, had you done it, you would have come out of it with glowing skin and hydrated hair. That’s because these gelatin-like sea plants — also known as microalgae — from the algae family are loaded with nourishing elements like vitamins, minerals, and antioxidants that make it a powerhouse addition to your beauty routine. Here’s what you need to know about the marine-derived ingredient.
The Benefits of Seaweed for Skin & Hair
When it comes to providing benefits, seaweed is a real overachiever. It has antimicrobial and antiviral properties and can be used to help moisturize both skin and hair. It has a few bonus benefits for the complexion: namely, brightening, exfoliating, and balancing oil production.
It’s also a great anti-ager thanks to what Julie Russak, MD, a board certified dermatologist and founder of Russak Dermatology in New York City, calls “mycosporine-like amino acids.” As she explains, the amino acids “function in protecting seaweed from UV radiation and, therefore, are involved in radical scavenging and DNA-repair systems.” What’s more? The polysaccharides in these sea plants “play a major role in inhibiting collagenase and elastase activity — enzymes that break down collagen and elastin and contribute to development of fine lines, wrinkles, and sagging skin,” she adds.
How to Add Seaweed to Your Beauty Routine
All of these elements work across skin types and are fairly easy to work into your routine. “Peptides and clean extracts from seaweed should be safe for sensitive skin as long as a vehicle that delivers them is also made with sensitive skin in mind,” Dr. Russak shares. That said, when in doubt, she says to go slow to start out if your skin can be a bit fussy with new ingredients.
