The Tyndall effect usually causes a bluish discoloration of the skin which is caused by fluid accumulation just under the skin because fillers can attract water and cause swelling. Thus, the bluish discoloration is usually also associated with swelling (which can give the appearance of bluish "bags" under the eyes). Based on the appearance of the photo, most likely what you are experiencing is prolonged bruising, which can, in some people, take weeks to months to resolve. Close follow with your injector can help determine the appropriate course of care. There are some laser treatments that can help speed the resolution of the bruise as well as oral or topical medications. Best of luck!
