I have deep tear trough and dark circles since I was born. I read that lack of fat under the eyes can cause it, but I also read that low and weak cheekbones can also create a hollow under the eyes that runs below the zygomatic bone that is right under the eyes (my case). If that's true, can cheek implants help? I've tried Restylane injections but they were of little help. Can implants make the hollow disappear or at least make it look fuller permanently?
