ASCORBIC ACID — Vitamin C. Powerful antioxidant and nutrient, very beneficial to the skin. Plays an essential role in building collagen, the connective tissue that makes up 70 percent of our skin. Vitamin C is also a natural preservative, protecting both the oil and water phases of cosmetics. Ascorbic acid is a water-soluble form of vitamin C. (See also Calcium ascorbate.) (INCI dictionary) 

ASCORBYL PALMATE, ASCORBYL PALMITATE — An oil-soluble form of vitamin C. (See also Ascorbic acid.) (INCI dictionary)

FERULIC ACID: Ferulic acid is an excellent antioxidant, neutralizing free radicals,thus preventing premature aging of the skin caused by free radical damage to elastin and collagen. Ferulic acid acts synergistically with other antioxidants, specifically vitamin C and E, to double their ability to protect the skin from UV radiation. (Interestingly, Ferulic Acid's antioxidant activity is actually boosted by exposure to UV light.) The addition of Ferulic Acid to solutions that contain l-ascorbic acid helps to stabilize 90% of the vitamin C (l-ascorbic acid) and 100% stability is conferred upon Vitamin E (tocopherol). Used in F*a*C*E Synergy Serum. (cellularskinrx.com)

L-ASCORBIC ACID: It is the most effective form of Vitamin C and acts as a powerful antioxidant. L-Ascorbic Acid is the only form of Vitamin C that is easily absorbed by the skin and is a key element in any anti-aging skincare regimen. Skin is exposed to a variety of environmental insults on a daily basis. UVA/UVB radiation, smoke, air pollution and stress all contribute to the free radical/oxidation process that breaks down the collagen layer of your skin. During this oxidation process, environmental insults cause the skin to form free radicals (O1 molecules) that need to attach to other molecules to become stable (O2 molecules). These free radicals attach to the skin's collagen molecules. This contributes to the breakdown of this collagen layer. Skin starts to look old and loses its natural firmness and elasticity. L-Ascorbic Acid protects your skin from environmental damage and prevents the formation of free radicals. L-Ascorbic Acid is necessary for collagen production and helps to stimulate your skin to produce healthy collagen layers. Over time, the L-Ascorbic Acid in the C + Firming Serum will help to reduce hyperpigmentation, lighten brown spots and improve the texture and firmness of your skin for a younger-looking, more radiant appearance. The 12% concentration of L-Ascorbic Acid in the C + Firming Serum is formulated at a lower ph to ease absorption. It is suspended in a simple stabilizing solution to maintain the effectiveness of the Vitamin C over time. (cellularskinrx.com)
