The concentrated treatment contains plant collagen amino acids, which guarantee an intensive anti-ageing, firming and anti-wrinkle effect. Plant collagen amino acids selected from Collistar Clean Research®, derived from the protein fibre binding of corn, soy and wheat, regenerate and mimic the structural action of animal collagen. Glycogen binds to plant-derived collagen, acting as an energy source to increase fibroblast metabolism and accelerate collagen production.
