How many types of seaweed do you know? A world to be discovered

There are about 27,000 different species of seaweed in the world. Fucus Vesiculosus or bladderwrack, used by La Espiral Verde in our skincare products, is brown algae that belongs to the kingdom of Protista and is also known as Sargassum. It grows attached to the rocks –which give remineralising properties, and its berrylike gas-filled bladders help keep the fronds afloat to promote photosynthesis. Properties of Fucus are based on several active principles such as alginic acid and other mucilage, fucoidine, laminaran and several carotenoids (provitamin factors).

Laminaria Digitata -commonly known as kelp or Kombu, is another seaweed with the same benefits as Fucus that we are currently using in our products as well.

In addition, we are also using Spirulina Platensis, a green-blue microalgae considered to be one of the richest natural source of nutrients (more than 50), vitamins (A and E) and minerals (13) that help renew tissues, counteract the effects of radiation, and stimulate blood supply to the most external skin layers and the immune system. For this reason, it is perfect to prevent skin infections. It also contains iron, zinc, beta-carotene, natural antioxidants, chlorophyll and phycocyanin, vegetable proteins, and essential amino acids. It has regenerating, remineralizing, decongesting, reductive, toning and anti-ageing properties. Moreover, it helps keep skin elasticity by activating the elastin and the collagen synthesis, and helps to fight skin spots as well.

Do you already know the beneficial properties of seaweed? La Espiral Verde strongly bets for them and become the star ingredient in our products

Scientists from the Institute of Aquaculture at the Stirling University in Scotland discovered a treatment for acne. The research revealed the cleansing qualities of certain fatty acids including some produced by algae. They found these fatty acids prevent the growth of Propionibacterium acnes, a bacterium that causes the common skin condition.

Some substances in brown marine algae such as phenols, beta-carotene, tocopherols and vitamins C and E, have great antioxidant, anti-free radicals properties which prevent early ageing of skin. Vitamins C and B3 (Niacin) have photoprotective properties and prevent the loss of collagen too. Fucoidans are polysaccharides that stimulate the production of collagen and inhibit the appearance of skin spots and wrinkles.

Algae contain carbohydrates that contribute to keep water in the corneum stratum, forming a protective film on the skin that prevents transepidermal water loss. These substances, together with alginates, preserve the optimal moisturising level of the skin.

Algae also have anti-swelling and anti-cellulite properties, as mineral salts –especially iodine, stimulate the general metabolism and osmotic exchanges thus provoking the elimination of superfluous liquids and toxins and stimulating circulation, vasodilation and lymphatic flow.

Why La Espiral Verde skincare products are so special?

The place where seaweed grows, the characteristics of the water, the conditions of harvesting, drying, milling and gelling, and the way the product is made are the clue.

Our previous experience in the development of patents to obtain and separate alimentary substances was useful to help us develop these same processes at the laboratory in order to achieve an ingredient with a greater amount of active principle and, therefore, greater cosmetic properties.

By thoroughly studying at the laboratory all these characteristics, collecting samples in different areas and tides, and even travelling to see how seaweed behaves in different environments, we were able to verify that the place, the water temperature, the exposure to atmospheric conditions, the ambient temperature, the lack of nitrites in the water, its salinity and opacity, the way seaweed is obtained and dried, as well as its texture among others, are factors that affect the proportion of active principles in the substances contained in both Fucus and Laminaria seaweed.

When including algae in our skincare products, we also thoroughly study which ingredient should be mixed before or after, the temperature, the reaction time of mixtures, the stirring, the way seaweed is added, and so on.

This way, the beneficial properties of our skincare products are considerably increased.
