Our best-selling C + Firming Serum contains a 12% concentration of stabilized Vitamin C in the form of L-Ascorbic Acid. This is the only form of Vitamin C that is easily absorbed by the skin. Other forms of Vitamin C, such as C-esters and magnesium ascorbates must first be metabolized by the skin before being able to be absorbed. This elegant water-free serum is the foundation of any proper, anti-aging skincare routine. The l-ascorbic acid is suspended in a glycol base to improve penetration and acts as a powerful antioxidant protecting skin cells from free radical damage due to exposure to UVA and UVB radiation, smoke, and other environmental pollutants. To protect from ALL forms of free radicals, apply CSRx Antioxidant Defense Complex first.

C + Firming Serum stimulates collagen production to firm the skin, corrects hyperpigmentation and prevents premature signs of aging. Antioxidant properties have been shown to last for up to 72 hours. Use C+ Firming Serum every day before any other skincare products and look forward to firmer, more radiant-looking skin within three weeks. For normal to oily skin. Dry skin users should apply a moisturizer after applying C + Firming Serum.
