Science
Mechanism of Action
As a positively charged polymer, Polyquaternium-29 selectively adheres to the negatively charged surfaces of the skin, creating a coherent, continuous film. This film effectively reduces electrostatic charges, provides a conditioning effect, and acts as a barrier to minimize transepidermal water loss, thereby supporting skin hydration.
