Why Don't Multiple Fraxel Treatments Destroy New Collagen?
I am having a series of 4 Fraxel treatments. I understand Fraxel Restore treats 20% of the skin, then there is aprox 1 month healing time between treatments. Why doesn't the second treatment destroy the progress made on the first treatment since the laser is passing over the same area? How does the laser "know" which area has not been treated?
