The benefits of seaweed for the skin

There's no denying it: The active ingredients sea-based products are on a roll! Collagen or marine sugars, seawater and algae are increasingly present in face and body care products, so much so that we now speak of marine cosmetics. Far from being a fad, marine ingredients, and seaweed in particular, have real beneficial properties for the epidermis. Whatever their color (brown, green, red...) or size (macro or micro-algae), these marine plants have it all... Find out why and how to enjoy their benefits for the skin!

Seaweed, a plant well assimilated by the skin

The reason why these aquatic plants are so interesting for our epidermis is that they have a great affinity with skin cells. In fact, there are many similarities between the biochemical structure of our skin and that of algae. Clearly, cosmetics made from seaweed are easily assimilated by the epidermis and particularly well tolerated! So The active ingredients extracts from these marine plants are proving extremely effective, with results that are often more convincing than those obtained from land plants!

Another thing that skin and aquatic plants have in common is that they are both subjected to different types of stress, which can cause damage to the organism. These include the sun's UV rays, wind, temperature variations and dehydration (during tides, for example). To survive, algae, whether on the surface of the water or in the depths of the oceans, must adapt to these repeated attacks. Its incredible resilience is directly passed on to us by incorporating it into our favorite cosmetics, in the form of oil or extract.

The benefits of seaweed for the skin

As a rule, these marine plants are rich in minerals, antioxidants, vitamins and essential fatty acids. These nutrients protect the collagen and elastin fibers responsible for skin suppleness and firmness. The production of these two substances, naturally present in the body, tends to decline over time. Algae can slow down this process, which is why, when incorporated into a face cream, they have the ability to firm the skin, and prevent cutaneous aging and the appearance of fine lines and wrinkles!

Beyond these commonalities, each species has its own specificities and virtues. Some are ideal for slimming treatments, others are unrivalled in their ability to combat skin imperfections or brown spots, and still others are champions of anti-aging or moisturizing!

These aquatic plants constitute a formidable reservoir of natural assets and are an integral part of our planet's biodiversity: there are more than 200,000 of them off the five continents, and the vast majority have yet to be analyzed! Only 30,000 species worldwide have been studied to date. While we wait to discover all the secrets of seaweed, let's take a look at Boreal Algae and Thalassiossira Antartica, used in Polaar skin care products to preserve skin beauty and boost hydration.

Boreal Algae and Thalassiossira Antartica, magical algae for the skin!

At Polaar, we've long been interested in the plants living in polar glaciers, and their incredible dermo-cosmetic properties. Forced to adapt to the unfavorable climate prevailing in Arctic zones (snow, icy oceans, hostile lands...) certain plants have developed interesting characteristics for the skin.

In the abysses of the polar oceans, our scientific teams have discovered Rhodimenia Borelia, a boreal algae which, under the influence of blue moonlight, synthesizes large quantities of phytomelanin - the plant version of melanin, produced naturally by our bodies to regenerate cells during the night. It has decongestant and soothing properties, and works to revitalize the skin as we sleep. We've incorporated it into our Polar Night Revitalizing Cream.


In the depths of the fjords, we have also identified an exceptional microscopic alga, Thalassiossira Antartica. To survive at -3760m in the harsh climatic conditions of the North Pole, it produces essential fatty acids, amino acids, carbohydrates and vitamins, which protect it from the extreme cold.

That's why Thalassiossira Antartica is one of the key ingredients in our moisturizing face care range Ice Source. By reinforcing the hydrolipidic film, it protects the skin from external aggressions and restores up to a third of the skin's natural moisture. Its nourishing and protective properties help to combat dryness and keep skin healthy and beautiful, even in sub-zero temperatures!

As you can see, seaweed is a super plant, rich in nutrients and antioxidants, and all-natural! So don't hesitate: used externally or internally, on your plate, as a dietary supplement or in your beauty cream, these treasures of the sea can do wonders for your health and preserve the beauty of your face and body more than any other ingredient!
