Key Ingredients

6 stabilized Vitamin C Esters to repair and diminish visible wrinkles through the rapid stimulation of collagen fibers within the skin. Skin’s elasticity is revived- giving back a firmer, more compact look and the complexion’s brightness is boosted offering a beautiful, luminous clarity.
C3 Plasma™ Bio-Technology: Our exclusive Plasma Technology super-vaporized delivery vehicle suspends the Vitamin C Esters and allow them to saturate the skin’s epidermis for superior absorption and utilization. The warmth of the skin heats the Plasma, infusing the epidermis with high performance anti-agers that can actually stop visible skin-aging in its tracks.
