I'm considering some dermal filler in my teat troughs as I have wide set eyes and dark circles. Hoping to decrease the shadow.I am worried out the risks though and don't want to look worse off. What are the dangerous and risks of permanent complications in this area? Is there a chance of necrosis, I noticed there is a small vein that runs under the eye. All the research only talks about necrosis dangers associated with the forehead and nasolabial folds.
