Brown Algae ( Laminaria digitata )
Laminaria digitata is a large brown alga in the family Laminariaceae, also known by the common name Oarweed. It occurs in the north west Atlantic from Greenland south to Cape Cod and in the north east Atlantic from northern Russia and Iceland south to France.
All seaweeds are rich in compounds that are of specific use in the cosmetic industry, such as polygalactosides, fucose polymers and ursolic acid.
Polygalactosides react with the protective outer surface of the skin and the ion-ion interaction form a protective moisturizing complex, while the fucose polymers are hygroscopic and act as hydrating agents and the ursolic acid can help form a protective barrier on the skin.
The seaweeds contain abundant non-essential and essential amino acids such as proline, glycine and lycine – all of these which are found in the elastic fibers of the skin as well. With this in mind, these ingredients alone would be helpful for the skin’s elasticity by increasing hydration and thereby maintaining and improving the skin’s elasticity. The seaweeds are also a major source of iodine, calcium, iron, copper, potassium, magnesium, vitamins A, B1, B2, C, D and E
Rich in polysaccharides and mainly alginates, Laminaria digitata is well known in the food and agriculture industry for its gelling properties. Rich in polyphenols and minerals, it is also eaten in salads for its remineralizing and refortifying qualities.
With age, stress and external aggressions, adult stem cells become older, lose their vitality and capacity to divide, so that skin renewal becomes slower and wrinkles appear and deepen.
The extract of Brown Algae has a high polyol concentration with protective properties, and also providing an energy reserve for our cells It.acts on adult stem cells in the dermis in 3 steps:
1 – It restores ageing adult stem cells of the dermis with their capacity for division,
thereby stimulating their action.
2 – It protects adult stem cells from ageing by preserving and prolonging their efficacy.
3 – It rejuvenates fibroblasts, stimulates collagen synthesis in mature skin and smoothes wrinkles.
It is an active substance capable of rejuvenating and protecting adult stem cells, so that our skin retains its eternal youth.
