Can Belotero Cause Yellow or Brown Discoloration Under the Eyes in the Tear Trough Area?

The skin of the tear trough area is very thin and has a tendency to bruise more than other areas. If the area bruises, it will be discolored. As the bruise is metabolized, it will change from purple to a more yellowish/green. The discoloration is from the extracellular blood and hemosiderin deposits under the skin (a normal occurrence with bruising). Best of luck.

Some of the causes for yellow brown discoloration of the skin after injections could be hemosiderin staining if you bruised in that area.  This is iron deposit from blood in the tissues.  Another consideration is that if you tan easily or have more pigment in your skin you may be experiencing post inflammatory hyper pigmentation. Keep in mind the product may look different in darker skin types than it does in lighter skin,  but either way it usually means it was placed too superficially. Time will usually resolve this but you can have it dissolved if you don't want to wait it out.
