NV ASCORBIC ACID

NV Ascorbic Acid has the active ingredient ascorbic acid encapsulated in polymeric particles with particle diameter larger than 200 nm. The technology developed by Nanovetores allows greater stability against heat and light as well as protection against oxidation of vitamin C in its most active form, ascorbic acid, ensuring benefits associated with its use, such as even skin tone, smoothing blemishes, improved hydration, texture and skin firmness, as well as helping to reduce expression lines. NV Ascorbic Acid can be used daily, providing, in continuous applications, its main benefits.

Vitamin C, or ascorbic acid, is a water-soluble and thermolabile vitamin widely used in cosmetic and skin care products, as it presents significant physiological effects on the skin, such as inhibition of melanogenesis, stimulation of collagen synthesis and antioxidant action, establishing a protective film and helping prevent skin aging. Thus, it acts through different action mechanisms, providing beneficial effects on aesthetic treatments designed to combat the signs of skin aging.

Ascorbic acid is the most active form of vitamin C but the most unstable due to its difficulty for stabilization.

Several more stable derivatives were developed. Ascorbyl palmitate, for example, has only one branch and although it penetrates the skin, it is limited in its conversion to L-ascorbic acid, the active form of vitamin C. In turn, magnesium ascorbyl phosphate is not able to go through the stratum corneum. Sodium ascorbyl phosphate has two substitutions and ascorbyltetraisopalmitate has four substitutions in its chemical structure. The greater the number of substitutedradicals, the lower the vitamin C activity of ascorbic acid derivatives. So, in terms of effectiveness, ascorbic acid is the most effective form of vitamin C and ascorbyl tetraisopalmitate the least effective.

MECHANISM OF ACTION

Vitamin C has antioxidant, depigmenting, and photo rejuvenation activity, it also reduces the signs of photoaging, improves the epidermis texture, and fight wrinkles (SCOTTI, VELASCO, 2007). It acts through different ways, providing beneficial effects on aesthetic treatments designed to combat the signs of skin aging.

Ascorbic acid acts on the synthesis of the supporting fibers (collagen), which are essential to ensure skin firmness. By improving this synthesis, it delays one of the most noticeable signs in skin aging. Considered a strong antioxidant, it also reduces and recycle vitamin E back to its active form, so that the antioxidant capacity of vitamin E is increased when they are associated (GUERRA; FANAN, 1994).

Ascorbic acid favors the synthesis of support fibers (collagen), being essential to ensure skin firmness and provide the delay of one of the most noticeable signs of skin aging.
