Can I apply a 50% TCA peel to my inner thighs, neck, under arms, knees, knuckles, vaginal region and elbows? I'm 25 years old.

I have a clear caramel skin and my whole life.. i apply just vaseline on my whole body. I have no skincare products.. but growing up, my inner thighs, neck, under arms, knees, knuckles, vaginal region and elbows are currently about 4times darker than my complexion and it’s really disgusting and embarrassing... people think i was bleaching and it went wrong.. but i have never bleached. So recently I bought 50% TA to apply to those areas.. would it work?
