I have the melasma mustache and melasma across my whole forehead. I received the laser treatment yesterday. First she applied a numbing creme on my face and I waited for 45 minutes for it to sink in. She did 3 passes with the laser, the 3rd pass hurt but was not unbearable.
It felt like little pin pricks. When she was doing my nose, I felt like I was going to sneeze and my eyes and nose were running. After the laser treatment- which took an hour- my face felt and looked severely sunburned and swollen. I would recommend an ice pack for the drive home.
As suggested, when I came home I had cold compresses in the refrigerator that I applied to my face the rest of the evening. Last night I slept with my upper body elevated (as suggested) and today I am not swollen at all. My face is red and tender looking. My face is too red to tell if the melasma is any better. I will post tomorrow or the next day and let you know my review.
