Regenlite left hyperpigmentation on chest and neck (Photo)

I have darker Indian skin and I got regenlite on 9/10/16. I had gotten it several times before with great results. 2 days after I had hundreds of hyper pigmentation marks all over my chest and neck. I'm so worried it's permanent. My doctor says no and gave me 4% hydroquinone. The marks have actually darkened. I'm so scared. They are not raised but they are all over my neck and chest. I have been religious about SPF. They are flat and round, like the shape of the laser. I'm beside myself. Thank you.
