What is hyaluronic acid? Where does it come from?
Discovered by scientists in 1934, hyaluronic acid is a special molecule that occurs naturally in the human body, an essential part of the support system of the skin and hair. It is the reason healthy faces look plump and dewy, and one of the ingredients that makes hair supple and radiant.
How does hyaluronic acid benefit the hair?
In skin care, hyaluronic acid is beloved for its ability to blur fine lines and take years off of the appearance of the complexion. A magnet for moisture, it attracts 1000 times its weight in water, giving it its signature plumping, freshening effects. In hair care, the effect is similar—instant hydration, bounce and shine. Incredibly nourishing, hyaluronic acid revitalizes hair by infusing it heavily with moisture.
