25% Vitamin C Face and Eye Serum with Matrixyl (polypeptides) is highly concentrated, stable to oxidation and unique in stimulating maximum collagen production. It also has additional polypeptides (Matrixyl), which act independently to stimulate collagen and thicken the dermis. This unique form of Vitamin C (Ascorbyl Glucoside) contains two glucose molecules that act to prevent oxidation and retain its efficacy until absorbed into the dermis. In the dermis, an enzyme (Glucosidase) strips away the glucose molecules, leaving active L-Ascorbic acid, which stimulates collagen production. This form of Vitamin C also has slow release properties, which ensures its effectiveness for several hours after application. When topically applied, Vitamin C decreases production of existing melanin deposits (hyperpigmentation) as well as decreases synthesis of new age spots by interrupting Tyrosinase production. Vitamin C fights free radical damage caused by the sun and environmental insults. Its light, non-comedogenic, oil-free emulsion penetrates quickly, leaving no residue. The results are fewer brown spots, fewer fine lines, firmer skin and tighter pores. This serum is recommended for use day and night after cleansing. Type of skin: All skin types. Key Ingredients: Glycerin: A humectant or “water magnet” that binds with water molecules and traps them in skin cells. Replicates and enhances skin’s self-moisturizing ability; Palmitoyl Oligopeptide: Peptide made up of Palmitic Acid (fatty acid) and amino acids. Considered as effective as Retinol for collagen stimulation and with no irritating side effects. Research shows it can increase collagen, elastin and hyaluronic acid; Palmitoyl Tetrapeptide 3: Also known as Matrixyl. A peptide made up of five amino acids that are linked together and attached to a fatty acid. Considered as effective as Retinol for collagen stimulation and with no irritating side effects. Research shows it can increase collagen and elastin production; Ascorbyl Glucoside 2%: Form of Vitamin C with Glucose. Contains two glucose molecules, which act to prevent oxidation and retain its power until absorbed by the skin into the dermis. Strong antioxidant which protects skin from ultraviolet radiation and neutralizes free radicals. Increases collagen production; Glycerin: A humectant or “water magnet” that binds with water molecules and traps them in skin cells. Replicates and enhances skins’ self-moisturizing ability.
