3-O-Ethyl Ascorbic Acid is a stable derivative of ascorbic acid, commonly known as Vitamin C. It is a potent antioxidant that helps protect the skin against free radicals and environmental damage. This ingredient has skin-brightening properties, promoting an even skin tone and reducing the appearance of dark spots and hyperpigmentation. 3-O-Ethyl Ascorbic Acid also stimulates collagen synthesis, which can improve skin firmness and elasticity. It further provides UV protection by inhibiting the production of melanin, thus helping to prevent sun-induced pigmentation. Additionally, it supports antioxidant regeneration in the skin, enhancing overall skin health.
