Detailed answer

Vitamin C, also known as ascorbic acid, has been found to effectively reduce dark spots and hyperpigmentation. It works by inhibiting the production of melanin, the pigment responsible for dark spots, thereby lightening the skin. Vitamin C also has antioxidant properties that can help protect the skin from damage caused by free radicals and sun exposure, which can worsen dark spots. Additionally, vitamin C helps boost collagen production, improving the overall texture and appearance of the skin. It is important to note that consistent and prolonged use of vitamin C in skincare products is necessary to see significant results in reducing dark spots.
