I read it is the most effective treatment to safely break up pigment. My concern is, what would I use between treatments against ‘rebound’ pigmentation? It can’t be HQ since thats what caused the issue in the first place. Or does this condition not need all the topicals in between like melasma does? (Spf 50 used constantly of course) History: 8 mts continuous use of HQ and when I called the doc to report the discoloration I was starting to see, he advised me to just keep going... Please, advise.
