Agar
Agar is a polysaccharide gum obtained from red seaweeds, valued as a natural gelling and film-forming agent. In cosmetics it stabilizes textures, builds viscosity, and adds slip for gels, masks, and emulsions without introducing oil.

Our take
Is Agar a Good Ingredient?
Good: a stable, inert gelling/film-forming polysaccharide that improves texture and reduces immediate moisture loss with a low likelihood of irritation, though it offers minimal active treatment.
What it does
Skin Benefits
Creates a soft, cushiony glide and forms a light film that can help reduce immediate moisture loss. Improves product feel without adding greasiness.
