What Makes Serious-C3 Plasma™ C Serum Unique?

Science-Based, High Performance Ingredients

Vitamin C Esters

6 stabilized Vitamin C Esters. Vitamin C Esters are the skin-loving derivatives of vitamin C - highly valued in skin care applications due to their consistent stability and superior ability to penetrate deeply into the skin. Stabilized Vitamin C Esters 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 C3 Plasma™ Bio Technology - A super-vaporized delivery vehicle which 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.
