I am an indian and i would like to know is it possible to get back your childhood skin by lactic acid .becuase my inner arms are unexposed and is much lighter than my face..
What i am planning to do is use
40 percent latic acid weekly
Kojie san daily once at night for 4 days
Use 25 percent zinc oxide sunscreen
Also use vitamin c 500gm daily

I wont use kojiesan one before and one day after lactic acid peel
If i do all of these how long would it take to get my orignal skintone back...
Thank you
