Vitamin C Brightening Concentrate helps promote a brighter, even skin tone while diminishing the appearance of dark spots. It's infused with the most advanced form of Vitamin C, Tetrahexyldecyl Ascorbate, which helps alleviate free radical damage and discoloration and prevents UV damage by boosting sunscreen and shielding cells from harmful UVA/UVB rays. It also repairs the skin by promoting Collagen Synthesis, which strengthens the dermal foundation. Tetrahexyldecyl Ascorbate formulation allows for better penetration for optimal results to soften, smooth, and brighten skin for a more radiant, even-toned complexion. No water is added, which means the product will not oxidize and turn brown.
