Can a low percentage TCA peel be used on my inner thighs and panty line area?

I have severe discoloration and dark spots/scars on my inner thighs and panty line that have developed over time from shaving and chaffing.Ingrown hairs would form and leave unsightly scars.I am a medium skinned person which makes the dark spots and scars more noticeable.It’s extremely embarrassing for me.I’ve tried different drugstore creams that have slightly lightened the area but did nothing to the dark spots.I don’t think a cream would help years of damage,I want to try something stronger.
