Had Co2 laser above and below eyes. Several areas took a long time healing, had resurfacing on some areas at later date. One area under the eye did not look sore but it was and was a little swollen. It is still swollen after 1 year and seems to be getting larger. Tretinoin products inflame it more. All of this is under the skin. What is it? In the picture it is a little purplish in color under the eye.
