Help with indentation and scarring from cyst removal with a new cyst (Photo)

First, i expect few (zero?) other doctors on this site to ever respond to a post like this. I am sorry to hear about your result. Of course it is not possible for me to comment of what your cyst might have looked like before and what was required to remove it since I could not know those things. Was this treated by a board-certified, fellowship trained surgeon with expertise in facial cosmetic surgery?? I caution you about having "the new cyst injected" -- with what? and why would anyone "inject it?" Was this a steroid injection of some type as I suspect? Steroid injections are known potentially to cause shrinking of the tissues around the injection and can cause indentation all by themselves. Again, all of these comments are just general suggestions since I am not your surgeon and I never examined you. Have you been using scar gel and vigorously massaging the healing area?  Once the area is truly healed, filler could be tried under the depressed area but this is not a simple thing. If you are unhappy with your current care, please seek out another expert in facial surgery with extensive experience in mole/cyst removals. Best wishes as you recover.
