Gelidium Sesquipedale Extract
What is Gelidium Sesquipedale Extract?
Gelidium sesquipedale extract derives from a red alga species (Rhodophyta) found in marine environments like the Atlantic and Mediterranean coasts. This seaweed is botanically rich in polysaccharides, including agar-like compounds and carrageenans, which give it gelling and water-binding properties. In cosmetic formulations, it falls under skin conditioning agents and is commonly incorporated into creams, lotions, serums, and masks. It works by drawing moisture to the skin's surface and creating a lightweight film that helps lock in hydration, improving texture without greasiness. Official databases like EU CosIng list it for humectant, masking, and conditioning roles, supporting its use in daily skincare routines for a refreshed feel.
Benefits
Supports skin hydration through natural moisture-binding polysaccharides.
