moisturizer/humectant film forming skin conditioning

Science

Mechanism of Action

This ingredient functions primarily as a film-forming agent, creating a subtle, continuous barrier that helps protect the skin. Concurrently, it acts as a humectant, drawing moisture from the environment and anchoring it within the skin, thereby boosting overall hydration. This dual action contributes to a significantly softer and more supple skin feel, maintaining optimal skin condition.
