Marine Algae and Eczema | National Eczema Association

Mother Nature has always been an important source of skincare ingredients. Despite all of the recent discoveries in skincare, natural ingredients have been a go-to for thousands of years. But it’s not just ingredients sourced from the earth that are potent — so are aquatic ones. Algae is famously a power player in the skincare world, but is it safe for people with eczema? We went straight to the experts to find out.  

How does marine algae work on your skin?

“Marine algae is seaweed, and the algae extract is commonly used in skincare products that are composed of various ingredients including carbohydrates, lipids, proteins, amino acids, minerals and flavonoids,” said Dr. Paul Yamauchi, medical director at the Dermatology Institute & Skin Care Center in Santa Monica, CA, and clinical assistant professor at the UCLA School of Medicine. “Marine algae has recently gained very high popularity as a natural ingredient to replenish and revitalize your skin.”

Marine algae exhibits several benefits for your skin. Known as rich sources of bioactive compounds, one study published in the journal Mar Drugs found that skincare products with marine algae increase skin hydration and firming effects.¹

Dr. Yamauchi explained that marine algae contains antioxidants, which reverse the damage from the ultraviolet rays of the sun to decrease fine lines and wrinkles and to restore collagen in your skin. “It can lighten age spots and even out your skin tone,” he added. “Marine algae has humectant properties that moisturizes and hydrates the skin. It exhibits anti-inflammatory properties that can soothe dry, irritated skin.”

Is marine algae a good option for people with eczema?

“Yes, it can be due to its soothing properties,” said Dr. Marisa Garshick, a board-certified dermatologist at MDCS Dermatology: Medical Dermatology and Cosmetic Surgery in New York City and New Jersey. “It works by helping to improve skin texture and strengthen the skin barrier. It can also help reduce redness and inflammation, two common symptoms of eczema. It’s important to remember that individual reactions may vary.”

Additionally, marine algae can ease discomfort caused by eczema. “Because marine algae contains lipids, it can relieve the itch and inflammation of eczema,” Dr. Yamauchi said. “The hydrating and moisturizing properties of marine algae manages the dryness and itch associated with eczema, which will allow you to scratch less.”

How do you know if marine algae is good for your eczema?

“It’s always best to test on a small patch of skin first as everyone’s skin can respond differently,” Dr. Garshick said. “Also, consult with your dermatologist who can provide personalized advice.”

Are there any risks associated with marine algae if you have eczema?

“There are minimal risks associated with marine algae for eczema-prone skin, but as with any skincare ingredient, an allergic reaction is possible,” Dr. Garshick said.

It’s also crucial to consider the whole formula of the skincare product. Dr. Yamauchi recommends avoiding ingredients that you are allergic to, such as preservatives and fragrances.

What’s the best way to add marine algae to your eczema skincare routine?

“If you want to incorporate marine algae into your eczema skincare routine, it’s best to use it in hydrating serums or creams applied after cleansing, when your skin can absorb moisture most effectively,” Dr. Garshick said. “Look for products with algae specifically labeled as soothing or suitable for sensitive skin, as well as products containing types of algae known for their gentle, hydrating properties, like brown algae or red algae.”
