All About Marine Skincare: Marine Ingredients & Their Benefits

The field of marine cosmeceuticals is both highly technical and incredibly natural: cutting-edge developments in cosmetology and pharmaceutical scientific knowledge are combined with the power and abundance of the oceans.

 

Ocean water and seaweed contain marine active ingredients incredibly rich in nutrients, minerals, vitamins, and antioxidants, making them beneficial for the skin. These seaweeds undergo osmotic diffusion that allows the transfer of elements from the highest concentrated area to the poorly concentrated area to restore balance. Because their biochemical structure is similar to human blood plasma, these ingredients are bio-assimilable and well tolerated by our skin. 

An insight into our powerful marine ingredients

Seaweed, an ancient yet powerful resource, thrives in marine environments. Its varieties range from tiny forms to several meters and come in various shades, including red, blue, green, and brown. Each seaweed species possesses a unique composition of bioactive molecules, including vitamins, micronutrients, minerals, antioxidants, proteins, amino acids, and essential fatty acids (omega-3, -6, and -9). This distinctive DNA gives each type its individual properties and powerful effects on the skin. We harness the vital properties of these marine ingredients to nourish and treat the skin and body.

 

The harsh conditions of the marine environment like extreme temperatures, high salinity, and constant UV exposure have driven marine organisms to develop powerful survival mechanisms. These natural adaptations offer unparalleled skincare benefits, surpassing many plant-based ingredients. Marine-based ingredients transform the skincare industry from anti-aging and deep hydration to strengthening the skin barrier. This rich marine biodiversity is the foundation of our skincare innovation—Ocean Therapy.

 

At Algotherm, we harvest most of our seaweed on the Brittany Coast in France. Each seaweed is converted into powder, aqueous, or oily extract used in cosmetic formulas. Seaweed, seawater and Blue Phytoplankton give the skin all the micronutrients that it needs.

What is Codium Tomentosum, and how is it beneficial in marine skincare?

Codium Tomentosum also known as green seaweed is composed of 85% water. It has antioxidant and texture-enhancing properties in skincare. It regulates skin hydration by enhancing epidermal water circulation while reducing water loss. It is rich in antioxidants, which help combat oxidative stress in the body, protecting our skin and contributing to healthy skin.

What is Dictyopteris Membranacea, and its benefits in marine skincare?

This brown seaweed is highly popular in cosmetics for its multiple benefits. Rich in essential fatty acids, sterols, and polyphenols, it is particularly effective in nourishing and revitalizing the skin. This algae is known for its restructuring and firming properties, helping to improve skin texture and elasticity. By stimulating the synthesis of skin lipids, Dictyopteris Membranacea strengthens the hydrolipidic barrier, offering enhanced protection against dehydration and external aggression. It helps neutralize free radicals that are responsible for oxidative stress. It prevents the signs of aging and maintains a radiant complexion. Products incorporating this alga hydrate, are firm, and make your skin look younger.

What is the ALGOGÈNE [4] patent and its benefit in marine skincare products?

A pioneering range, OCEAN LIFE boasts a high concentration of ALGOGÈNE [4], the most complete complex of patented anti-aging marine active ingredients. This product is the result of several years of research in our laboratories. ALGOGÈNE [4] draws its power from a subtle combination of 4 exceptional algae activating 35 youth genes for a complete anti-aging solution, acting immediately and durably on all signs of aging. It works to reduce wrinkles and dark spots. It firms and plumps the skin.

What is Seawater, and what are its benefits in marine skincare?

Seawater is a precious ingredient in cosmetics due to its richness in minerals and trace elements, such as magnesium, calcium, potassium and zinc. These essential components help to hydrate and revitalize the skin, improving its natural mineral balance. Seawater also has soothing and anti-inflammatory properties, ideal for sensitive and irritation-prone skin. It helps to strengthen the skin barrier, thus protecting against external aggressions and promoting cell regeneration.

What are Blue Phytoplankton, and how are they beneficial in marine skincare?

Blue Phytoplanktons are special marine microorganisms, rich in essential fatty acids, vitamins, minerals, and antioxidants, which provide deep hydration and revitalize the epidermis. Its nourishing properties strengthen the skin barrier, protecting the skin from external aggressions and dehydration. 


But that's not all: Phytoplankton Bleu is also known for its regenerating and repairing abilities, promoting cell renewal and visibly reducing signs of aging. Plus, we harness the power of other types of plankton and even marine lichen, bringing you a skincare experience enriched with the best of marine biotechnology.
