Science
Mechanism of Action
This ingredient functions as a potent film-forming agent, constructing a flexible, non-occlusive barrier on the skin to significantly diminish transepidermal water loss. It acts as a humectant, binding moisture within the skin, and a skin-conditioning agent. Certain forms exhibit a unique cage-like structure that optimizes moisture retention, leading to visibly softer and smoother skin.
