Science
Mechanism of Action
This ingredient functions primarily as an effective moisturizer and conditioning agent. It actively preserves the skin's intrinsic moisture by forming a high-capacity moisture-binding barrier on the surface. Furthermore, it aids in replenishing natural oils and proteins, thereby maintaining optimal skin condition and delivering conditioning benefits with a non-greasy finish.
