Eyebrow skin damaged after threading. Is there anything I can do?

I would really recommend RF resurfacing and PRP. You need to have few treatment but it will help greatly. 

Very unusual reaction to the threading.  It looks like it is fairly superficial, but always tough to tell in pictures.  If it is, some erbium resurfacing may be able to remove the raised areas and make it appear smoother.  See someone who has a variety of lasers and I bet there is something that can help this. 

I am so sorry that you have had such a bad threading issue. My best advice would be to schedule a consultation with either a board certified plastic surgeon or cosmetic dermatologist to discuss whether or not there is any kind of treatment that might help smooth out the skin in that area.  My best,

There are things that can be done to improve it. I think fractional laser resurfacing would be helpful. Make an appointment with a board certified plastic surgeon or dermatologist. Tanning is not good when lasering, so you will need to avoid sun exposure and tanning booths.
