Hello there,Thank you for your question. Though the brown spots will eventually fade, a 3-month course of hydroquinone may help reduce the "hyper pigmentation." You could also consider laser toning with a 1064NdYAG, 2940 Pixel or even possibly an IPL (depending on your Fitzpatrick skin type and how the pigment actually looks after the aforementioned treatments). You could also consider chemical peels.The treatments all do need to be done in sections because doing the entire body would be too much. I really recommend seeing your dermatologist and having an honest discussion on what would be the best protocol for you. Hope this helps.All the best,Carlos Mata, MD, MBA, FACS
