Polysaccharides are responsible for the skin’s natural ability to hydrate and retain water. They are also essential for skin repair and renewal.
Dry skin (lines and wrinkles, loss of elasticity, etc.) is caused by two main factors:
- Damage of the skin’s protective barrier which results in natural water loss
- A natural reduction in the concentration of the skin’s polysaccharides
Damaged skin needs to be protected at the surface and allowed to heal from within. Sulfated polysaccharides of Porphyridium have shown to potentially improve the skin barrier in dry skin and also improve the visual and sensorial appearance of the skin. Utilizing its superior rheological properties the sulfated polysaccharides are excellent bio-lubricants with superior characteristics as compared to hyaluronic acid.
Studies have shown that topical application of sulfated polysaccharides has positive effect on the epidermal regeneration and its adherence to the dermis, which could improve the surface topography of dry or aged skin and increase the lasting effect of moisturizers.
