What Is Gigartina Skottsbergii Extract?
Gigartina Skottsbergii Extract is derived from Gigartina skottsbergii, a red alga that grows in the cold South Pacific waters off the coasts of Chile and New Zealand. Rich in sulfated polysaccharides such as carrageenan, the algae also contains proteins, amino acids, vitamins and trace minerals that help retain moisture and support healthy skin. Coastal communities have harvested this sea plant for generations to thicken food and soothe rough skin, but its cosmetic potential gained wider attention in the 1990s when formulators began looking to marine ingredients for gentle hydrating power.
To create the extract, freshly collected algae are cleaned, then soaked in water or a water-glycerin mix to draw out the soluble compounds. The liquid is filtered to remove plant solids, concentrated at low heat to protect delicate nutrients, and finally dried or blended into a stable solution. The result is a clear to reddish-brown ingredient that disperses easily in water-based systems.
You will most often find Gigartina Skottsbergii Extract in moisturizing creams, anti-aging serums, gel masks, after-sun lotions and soothing toners. Its film-forming ability also makes it popular in hydrating face mists and leave-on hair conditioners.

Minerals and natural sugars help soften rough patches and give the complexion a smoother more supple feel. In a formula the extract improves glide, adds a subtle cushiony texture and supports the skin’s own barrier so the face feels calm and refreshed after use.
