High molecular weight hyaluronic acid is a valuable cosmetic ingredient, renowned for its excellent moisturizing properties. Thanks to its larger molecular structure, it forms a protective barrier on the skin's surface, helping to prevent dehydration by limiting water loss. This form of hyaluronic acid immediately improves skin texture, smoothing fine lines and providing a plumping effect. By creating a film-forming layer, it also helps reinforce the skin's barrier against external aggression, while providing a feeling of comfort and softness. Ideal for dry or mature skin, high-molecular-weight hyaluronic acid ensures long-lasting hydration and a visibly more radiant, revitalized complexion.
Kappaphycus Alvarezii, a red algae also known as carrageenan, is highly prized in cosmetics for its many benefits. Rich in polysaccharides, it provides intense, long-lasting hydration to the skin, helping to maintain its elasticity and suppleness. Its film-forming properties create a protective barrier on the skin, preventing dehydration and protecting against external aggressions. In addition, Kappaphycus Alvarezii has soothing and anti-inflammatory properties, ideal for sensitive or irritated skin, reducing redness and irritation. Its active ingredients also stimulate cell regeneration and tissue repair, contributing to smoother, firmer skin. Cosmetic products formulated with this algae provide deep hydration, reinforced protection and revitalization, leaving skin soft, radiant and healthy.
Seawater is a precious ingredient in cosmetics thanks 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 skin prone to irritation. It helps strengthen the cutaneous barrier, protecting against external aggression and promoting cell regeneration. In addition, its detoxifying effects help purify the skin, eliminating impurities and toxins for a clearer, more radiant complexion. Cosmetic products formulated with seawater provide intense hydration, enhanced protection and a lasting sensation of freshness and well-being for the skin.
