I had a sample patch of CO2 laser resurfacing done on the lowest frequency, which I believe was 1.1 It’s been 36 days and you can still see the laser track marks and a purple square. I see the Dr again in 1 month to further address this. I’m concerned as I am olive skin and feel like this is permanent. What is going on with this mark? Is it permanent? They’re saying it’s Post inflammatory Ethyrema. Not sure if this is correct? The mark will DISAPPEAR if I press it and then come right back after
