VC is most well known for its outstanding contribution in whitening. We all know that melanin formation is a complex process. First, tyrosine must combine with tyrosinase to form dopa, and then DOPA will be converted into DOPA quinone through the catalysis of reactive oxide (ROS), and finally melanin can be formed.
VC can effectively reduce the activity of tyrosinase, cut off the connection between tyrosine and dopa, so as to prevent the formation of melanin, and can also reduce the melanin that has been formed. Melanin has never seen this battle before. Of course, it will surrender immediately and return the skin to be white and decent~

Anyway, if you have something to do, you will be able to oxidize vans. But this VC will be happy after oxidization, but it will lose its activity and no effect. How can consumers spend money to buy loneliness?
