Tetrahexyldecyl ascorbate is a stable form of Vitamin C and unlike ascorbic acid, it is oil soluble.
What are the benefits?
It is an antioxidant that prevents lipid per oxidation (protecting skin lipids from free radical damage), and it is also used to improve and maintain the overall condition of the skin. Manufacturers also say that it can reduce UV damage and stimulate collagen. According to research, tetrahexyldecyl ascorbate can help to achieve a more even skin tone by inhibiting pigment production and providing skin-lightening and brightening properties to a formulation.
Some researchers suggest that because of its fatty acid element, this type of vitamin C has a higher affinity for the skin. It works well in conjunction with other sources of vitamin C and retinol to maximise effectiveness.
