Key Ingredients
Silk Proteins (Sericin + Fibroin): the two key protein fractions of natural silk that penetrate the skin and hair to deliver extraordinary smoothness, strength, and a luminous sheen
Hyaluronic Acid: works alongside the silk proteins to provide deep hydration and plumping, ensuring this concentrate delivers both silk-smooth texture and visible moisture
Peptides: complement the silk protein complex to add collagen-stimulating benefits to the smoothing and strengthening action of the silk fractions
Niacinamide (Vitamin B3): brightens and supports barrier function alongside the silk complex, contributing to the overall skin clarity this luxury concentrate delivers
Squalane: lightweight carrier that ensures the silk protein concentrate absorbs beautifully into skin without greasiness, leaving only the luminous, silky finish
