Watch Out for Lasers With Melasma
You are absolutely right to be scared of lasers when you have melasma. Coolaser is no different than any of the others. It can make things worse instead of better. I would recommend chemical peels such as Cosmelan. These seem to get the melasma under control. The problem is that we have nothing available that will guarantee that the discoloration does not come back. Sun protection is a must, of course, and it really helps hold off recurrence. Hope that helps!
