With natural Vitamin C: the daily glow activator.

Vitamin C is a powerful antioxidant that helps protect the skin from environmental stress while supporting a more even, radiant tone. In this formula, a gentle yet effective 2% form works on the skin’s surface to refine texture and enhance brightness. The result is skin that looks smoother, more elastic and visibly luminous – every day.

Botanical synergy for lasting radiance.

Ferulic acid and sea buckthorn oil strengthen antioxidant protection while helping to calm and support the skin. Rosehip and avocado oils provide essential fatty acids for smoothness and comfort, while hyaluronic acid delivers lasting hydration. Together, they form a balanced, high-performance formula that keeps the complexion even, resilient and naturally radiant.
