An active ingredient derived from a single-celled microalgae naturally found in the salty environment of the Red Sea. It possesses the unique ability to synthesize and secrete substantial amounts of phycocolloids, which encase the cell like a gel capsule, serving as a distinctive protective mechanism against moisture loss and UV radiation. Additionally, these phycocolloids exhibit strong antioxidant and anti-inflammatory properties and are rich in lipids and polyunsaturated fatty acids, delivering an immediately noticeable and long-lasting tightening effect.
