What it is
Polyglycerin-6 is made by linking glycerin molecules into a short chain. It draws water in like glycerin but is larger, so it feels less sticky and stays closer to the skin surface. It also acts as a mild solvent for other ingredients.
What it does well

Polyglycerins are used as humectants where a formulator wants moisture-binding with a lighter, drier skin feel.
