CO2 laser is a second degree controled burn. When properly performed for etched wrinkles it should scare animals and small children for ten days. At exactly two weeks, our patients are able to put on makeup and go to work. if they heal faster than that, they will likely not get an optimal result. they may remain pink for weeks or months. This is capillary blood supply to the healing process. The longer they are pink, the tighter they seem to get. When the wound is fully healed, the capillaries reabsorb and pinkness dissapears. At this time, they can use Retin A. However this may cause pinkness to return. If very sensitive we use full strength about every fourth day and progress to every day as tolerated.We had the first Coherent Ultra-pulse laser in our area, and performed 350 full face cases under twighlight sleep.(this procedure is too painfull to do under local when properly done.) After mastering the learning curve, we produced a video to teach physicians our technique. However, after a few years we were dissapointed with the long term results. The two week healing period was exactly the same as the Phenol Peel. But the Phenol was far superior in removing deep wrinkles and lasted thrice as long or more in most patients. We no longer use laser for deep etched wrinkles. Phenol is far superior. At the Boston Meeting of the American Society of Plastic Surgeons, a show of hands revealed only one third of the plastic surgeons present knew how to do phenol peels. It is becoming a lost art, but there is nothing on the planet as effective. We use erbium for brown spots and fine lower lid wrinkles.
