In my second LHR session for the bikini area the lower area darkened. Time passed and it started getting lighter and lighter. I wanted to try hydroquinone for the area but I stopped after 3 applications. Now that the area is way better and lighter I went back to continue my LHR and the color didn't change. I want to avoid getting burned by lightening the area, is chemical peeling a good option ? What do you recommend and are the results guaranteed or it depends on my skin ?
