How can I get rid of these very stubborn sunspots? Looking for dr. In NY (Photo)

I had 2-3 photofacials done only on spots. Although the spots have lightened spots the last photofacial burned me and left me with PIH which is fading. Conservative settings were used and increased with each visit. Gentlemax on alexandrite setting was used. What are my options now? Seems if setting is too low no effect takes place & if raised it and burns me. Should I switch to yag setting? These spots make me miserable! I want to get rid of them or at least significantly lighten them.
