SILK CRYSTAL® associated with gold flakes for maximum cosmetic benefit

SILK CRYSTAL® GOLD FLAKES COMPLEX contains pure 24-carat gold flakes.

SILK CRYSTAL® GOLD COMPLEX uses colloidal gold nanoparticles.

SILK CRYSTAL® maintains the benefits of silk to rejuvenate and hydrate the skin.

Silk Fibroin is a protein found in natural silk that offers soothing and antioxidant cosmetic benefits. Our patented enzymatic process allows us to maintain this protein in a microporous structure: SILK CRYSTAL®.

The association of SILK CRYSTAL® and gold maximizes antioxidant effects and boosts UV protection.

The precious combination of SILK CRYSTAL® with gold flakes adds a luxurious touch to your cosmetic formula.

SILK CRYSTAL® GOLD FLAKES COMPLEX brings instant shine to improve skin radiance.

Colloidal gold inhibits the generation of Reactive Oxygen Species (ROS) and traps free radicals, which degrade skin components.

Integrating gold in SILK CRYSTAL® GOLD COMPLEX therefore increases the antioxidant power of silk.
