I had hyperparathyroid surgery over three years ago and ever since I have a 3.5 inch visible scar on my neck. The unfortunate part about it beyond the scar itself is that the surgeon never found the abnormal gland after a seven hour surgery. You can imagine that I was devastated.
I have tried all kinds of laser therapies (fraxel, PDL, IPL, 1024 nm, etc...) but none have worked...
