GrenzCine® Sērum will increase firmness and hydration of the skin while providing the benefits of diminished fine lines and wrinkles, increased luminosity and improved skin tone, texture and elasticity.

Product Description:

GrenzCine® Sērum is formulated to help increase the firmness of (thicken) our skin.  This formulation, combining our renowned, patented Vitamin C sērum plus Polyamine-DAB®, is a new patent pending discovery resulting from 30 years of clinical research.

As you age your skin becomes thinner and your collagen level decreases.  Lasers, peels, retinoids, the sun and over-exfoliation may also contribute to thinning your skin.

Our innovative sērum works using the Polyamine-DAB® from the “outside in” and the Vitamin C from the “inside out”, leaving the skin more luminous and youthful-looking.

  • Increases skin’s luminosity.
  • Diminishes fine lines and wrinkles.
  • Increases appearance of more youthful skin.
  • Improves skin tone, texture and elasticity.
  • Oil-free, alcohol-free, hypoallergenic, non-comedogenic, dermatologist tested, recommended by physicians and clinically proven.

Polyamine-DAB® (1,4-Diaminobutane) | L-Ascorbic Acid USP (pharmaceutical grade Vitamin C). 

Polyamine-DAB® or 1,4-Diaminobutane is a polyamine which is naturally present in our bodies. It is known to play an important role in the aging process of our skin, essentially making our cells and collagen work more efficiently.¹

L-Ascorbic Acid is pharmaceutical-grade Vitamin C and the form of topical Vitamin C that our body can use most efficiently.  USP stands for United States Pharmacopeia.  It refers to the highest purity of the ingredient and is a pharmacy standard used worldwide by the pharmaceutical industry. Vitamin C is known to boost collagen and reduce free-radical damage and environmental stress on skin to help skin look and act younger.

This formula helps to reverse the signs of aging.  The combination of Polyamine-DAB® and Vitamin C is unique to Vivier Pharma and a patent is pending on this new formulation. Polyamine-DAB® is the result of 30 years of clinical research and is clinically proven.  Over the past 20 years, Vivier Pharma has developed its internationally acclaimed patented, stabilized, water-based Vitamin C anti-aging sērums.
