About
A large polymer that improves texture, stability, or film formation more than it directly treats skin.
This is a high-molecular-weight polymeric ingredient used to thicken, stabilize, bind, or form films. Polymers of this size are generally expected to have low dermal penetration, so risk tends to come more from formulation quality or residual monomers than from the finished polymer itself. That makes it fairly safe, though not especially beneficial as a skin-care active.
Function
