Alginates are obtained from brown algae. The cell walls of brown algae contain alginates and cellulose as main structural components. Because of their many different uses, alginates for cosmetic use are extracted directly from the brown algae. Cellulose forms the “slimy” part that ensures the cell walls remains firm. This cell wall structure is specific to brown algae, and makes the skin both firm and flexible. The combination of aloe vera and brown algae forms the extract Actisea 100. The primary ingredient of this association is the bioactive sugar (also called oligosaccharide) from the two plants. They leave an active moisture film on the skin and support cell stimulation as well as strengthening the protective mechanisms of the surface of the skin.
