Science
Mechanism of Action
As a short polymer, this ingredient functions by forming a protective film on the skin and hair surface. This film actively fills in microscopic irregularities and areas of damage, leading to a perceptibly smoother feel. Its superior cling properties contribute significantly to retaining moisture, thereby improving skin condition and suppleness.
