I'm new to this site, and I don't know how to search for the answer, but here's are pictures to help describe my problem. I have little spots all over my back. I've been to several Dermatologists, but they act like they've never seen it before. My question is how to effectively lighten the hyperpigmented spots without having to do spot treatments on each and every one? Is there something that can lighten the spots without lightening my base skin tone?
