There’s a reason that seaweed and algae are surfacing as main ingredients in grooming products: The nutrients may help provide both protection against skin-aging toxins, as well as hydration and collagen boosts. According to Dhaval G. Bhanusali, M.D., a board-certified dermatologist at Hudson Dermatology and Laser Surgery in New York City, “When used in haircare, they may also help nurture strong hair, while promoting moisture and healthy shine.”
Different types offer different benefits, but most are packed with proteins, vitamins, minerals, and antioxidants. Time to give your grooming routine a deep-sea boost.
OSEA Brightening Serum
OSEA Brightening Serum [$68] seeps into the layers of your skin to help reverse damage and encourage healthy cellular turnover. That’s due to ingredients like seaweed and, notably, ferulic acid in red algae, which Bhanusali cites as “one of the more powerful antioxidants on the market.”
The Seaweed Bath Co. Exfoliating Detox Body Soap
Ocean-floor ingredients work to moisturize and calm skin in The Seaweed Bath Co. Exfoliating Detox Body Soap [$8]. It uses a seaweed called bladderwrack to condition and rejuvenate skin while flushing away grime.
Marlowe Shave Cream
Your skin’s most sensitive during a shave, so you need a lubricating agent that addresses irritation. Marlowe Shave Cream [$13] has an algae extract that works with willow bark, which Bhanusali notes is rich in anti-inflammatories.
Bumble and bumble Seaweed Conditioner
A revitalizing conditioner is one of the best ways to incorporate sea-sourced plants into your hair regimen. Bumble and bumble Seaweed Conditioner [$27] packs a trio—marine seaweed, spirulina, and kelp—that magnifies moisture retention for healthy movement and natural shine.
Elemis Pro-Collagen Marine Cream SPF 30
Elemis Pro-Collagen Marine Cream SPF 30 [$128] is a broad-spectrum SPF moisturizer fueled by chlorella algae, a buzzy ingredient believed to be full of B vitamins and anti-inflammatory properties. Combined with padina pavonica algae, chlorella boosts collagen production for improved suppleness and elasticity—all while protecting you from sunburns.
Mario Badescu Seaweed Cleansing Soap
Mario Badescu Seaweed Cleansing Soap [$14] also employs bladderwrack seaweed to provide a soothing, refreshing wash. Bhanusali suggests rotating it into your regimen one or two times weekly, especially if you have oily skin.
