Detailed answer

Vitamin C is a powerful antioxidant that can help brighten and even out the skin tone, making it effective in fading dark spots. It inhibits the production of melanin, the pigment responsible for dark spots, and promotes cell turnover, which helps to fade existing spots. Vitamin C also has brightening properties that can help improve the overall appearance and radiance of the skin. However, it is important to note that the effectiveness of vitamin C for fading dark spots may vary depending on the concentration and formulation of the product used, as well as individual skin characteristics. Consistent and long-term use, along with sun protection, is key to achieving the best results.
