Vitamin C, also known as ascorbic acid, is a potent antioxidant that offers numerous benefits to facial skin. It helps protect the skin from free radical damage caused by UV rays and environmental pollutants, preventing premature aging and reducing the appearance of fine lines and wrinkles. Vitamin C also promotes collagen production, which improves skin elasticity and firmness, giving a more youthful appearance. Moreover, it brightens the skin, fades dark spots, and evens out skin tone, resulting in a healthier, more radiant complexion overall.
