I have very bad hyperpigmentation on my legs from insect bites and ingrown hairs, along with open pores that are brown. It is getting worst. I bought 25% at home TCA peel and have been preparing my legs by using a 3% hydroquinone cream for the past two weeks. I am light tanned complexion (caribbean ethnicity mainly african). I plan to do a spot test first but think i should treat the entire area rather than spots because its everywhere. Should I dilute this 25% or is it safe to use on legs.
