L-ascorbic acid (vitamin C) is an essential nutrient which has many cosmetic benefits. It is a remarkable antioxidant and can scavenge reactive oxygen species and other free radicals, protecting the skin from oxidative stress. It can stimulate collagen synthesis by promoting cross-linking and stabilizing collagen molecules, upregulating collagen genes, increasing the transcription of the tissue inhibitor of matrix metalloproteinase 1, and inducing fibroblast proliferation. It reduces pigmentation by suppressing tyrosinase, which is important for melanin production. It is an anti-inflammatory agent and can be used to treat inflammatory skin disease such as erythema. Together, L-ascorbic acid provides powerful anti-aging properties and has been shown to reduce wrinkles, improve elasticity, and protect against sun damage. Stability and absorption of L-ascorbic acid is a concern. While the anhydrous L-ascorbic acid might be the most stable form, adding vitamin E not only helps stabilizing L-ascorbic acid, but the two have synergistic effects on anti-aging. Used in: philosopy's turbo booster c powder and SkinCeuticals.
Ascorbyl tetraisopalmitate (Tetrahexyldecyl Ascorbate) is a molecule derived from vitamin C and isopalmitic acid. Pure vitamin C has several drawbacks for cosmeceutical use, most important of which is the low stability. Chemically modified vitamin molecules are more stable, and pure vitamin is released from the derivatives inside the body. Therefore, the effects of Tetrahexyldecyl Ascorbate are similar to those of vitamin C, most importantly it is able to act as an antioxidant. Ascorbyl tetraisopalmitate reduces the production of oxidizing agents, which contribute to cell damage after exposure to UV or chemical hazards. This effect is even stronger in the modified molecule than in pure vitamin C. Additionally, Tetrahexyldecyl Ascorbate protects against DNA damage and skin darkening caused by UV exposure. Finally, skin visual appearance is also improved by Ascorbyl tetraisopalmitate, as it promotes collagen synthesis and acts as a hydrating agent in reducing skin roughness.
Ethyl ascorbic acid is a molecule produced by modifying ascorbic acid, commonly known as vitamin C. This modification is done to increase the molecule’s stability and enhance its transport through skin, as pure vitamin C is easily degraded. In the body, the modifying group is removed and vitamin C is restored in its natural form. Thus, ethylascorbic acid retains the benefits of vitamin C, such as antioxidant activity. Furthermore, it is even more potent in reducing skin darkening after UV exposure. It even has some additional effects, not observed in pure ascorbic acid, such as promoting nerve cell growth or reducing chemotherapy damage. Finally, the slower release also ensures that no toxic effects are observed when using this vitamin C derivative.
