Is Skin Scarring Permanent After PDL Vein Treatment to Face? (photo)

I had PDL veing treatment done on my face 2 months ago. My left eye swelled up pretty bad, but the swelling went away after a week, no blister or brusing, BUT, I have a scar left on my skin under my eye which hasn't gone away. The scar looks like a small raised triangle & around the scar is indented & probably the result of tissue damage under the top layer of the skin. The technician told me that it would not be permanent but I'm affraid. Is that normal & will it go away? Thanks. Mandy
