I got the palomar non-ablative laser resurfacing treatment done to my entire face to help with melasma a week ago. As expected my skin was red for a couple hours followed by slight puffiness. The next day I noticed the dark spots had gotten darker and I had this grid like print on my face which I was told is normal and the dead cells will flake off. I havent had any flakiness and the spots are the same (a week later)...how long do I wait till I notice flakiness or skin renewal ?
