Vitamin C serum benefits for skin whitening

There is a pharmacological action of vitamin C in the case of skin whitening. As it is an antioxidant, it tries to reduce the free radicals accumulated in the skin pores.

 How can free radicals accumulate in the pores? It’s another story. When our skin is exposed to UV rays, reactive oxygen species (ROS) are formed in our skin. And these ROS are free radicals.

These radicals create oxidative stress which stimulates melanocytes to secrete more pigments. This is hyperpigmentation. What vitamin C does is, prevents the oxidative stress of ROS as a reducing agent. This prevents hyperpigmentation.

And also vitamin C cures the destruction caused by the free radicals to the skin. After all the skin whitening quality is obtained by vitamin C. This is why vitamin C serum benefits skin whitening.

Why does it take long to heal your wounds? This is because your collagen synthesis is slow and your stratum corneum is thin. Vitamin C is a key factor in collagen synthesis. Therefore, it boosts up the collagen formation in the skin and fastens the wound healing.

This property of vitamin C not only helps wound healing but also it fastens the cure of acne scars and photodamaged skin.

The chemical basis of this property is that vitamin C is the cofactor for prolyl hydroxylase and lysyl hydroxylase.

What are these enzymes though? They are the enzymes that catalyze the hydroxylation of proline and lysine residues of procollagen. This catalyzation helps the transformation of procollagen to collagen by making a triple helix conformation of collagen.
