Definitive Collagen Activator Serum

Antioxidant-rich repair serum

A transformative collagen serum empowered by next-generation peptide technology and antioxidant protection to firm the skin, refine its structure, and inhibit its degradation.

Formulated with the very best peptides for collagen production, this brightening serum mimics the skin’s natural collagen production process to reduce the appearance of fine lines and wrinkles and enhance skin elasticity. At the same time, antioxidants, alongside bio-optimised and anti-inflammatory agents, protect skin against the environmental aggressors that accelerate skin ageing, whilst reducing senescent cells and, in turn, signs of inflammageing.

With daily use, as fine lines and wrinkles fade, skin appears smoother and healthier, and becomes more resilient, with a brighter, more radiant natural state.
