What GrenzCine Serum does
Vivier lists three benefits: it helps visibly reduce the appearance of deeper fine lines and wrinkles, boosts skin firmness and volume with improved elasticity, and enhances skin smoothness and radiance. The brand describes the intent as restoring volume, density, firmness and elasticity.
Key ingredients
Vivier lists 10% vitamin C as L-ascorbic acid USP together with Polyamine-DAB growth factors. It is the only serum in the range that combines the brand’s growth factor technology with its vitamin C.
Who it is for
All skin types, especially mature skin, per Vivier. It is the serum equivalent of GrenzCine Face, and people often use one or the other rather than both.
How to use it
Two to three drops in the palm, applied as a thin layer to face, neck, chest and the backs of the hands. Vivier says once or twice daily on clean dry skin.
