This serum is rich in low and high molecular weight hyaluronic acid (remarkable plumping, hydrating and softening properties), and contains sweet almond oil and vitamin E. High molecular weight hyaluronic acid creates a hydro-elastic film on the surface of the hair and skin that allows maintaining hydration and achieving a smoothing effect. Low molecular weight hyaluronic acid is easily absorbed. The two hyaluronic acids act synergistically to recreate the ideal physiological environment for the scalp, restoring youth to the skin and natural hydration to the hair. Sweet almond oil nourishes the skin and the hair acting as a supplement to the lipid component, while vitamin E provides powerful antioxidant and soothing action and protects against UV rays. For use with the oxygen concentrator, refer to the rituals manual.
