I got Fraxel Laser treatment done twice and then a CO2 laser treatment one time in order to treat my laceration above my eye. I impulsively smoked 4 or 5 puffs of a cigarette not knowing it would do anything. I later found out online that even one puff can have an effect on the oxygen in your blood. Will this have any impact on how my scar will heal. And it has been about 3 weeks since I got my last the CO2 laser treatment done.
