Vitamin C plays an important role in collagen synthesis, essential for maintaining the structure and elasticity of the skin. In addition, it has antioxidant properties that help protect the skin from free radical damage caused by sun exposure, pollution, and other environmental factors.

Regarding melanin formation, Vitamin C has been shown to inhibit the activity of the enzyme tyrosinase, which is involved in the production of melanin. This can help reduce the appearance of dark spots and uneven skin tone.
