Lips
Bruising is very common after lip injections and thats seems to be the case in the pic you have posted. I do not think this is Necrosis but again, thats based on the pic you have posted
Hi Gems. It does not appear to be necrosis. In fact we cannot see in the picture the blue color you are speaking about. If in fact there is a bluish area, it could be a bruise or something called the Tyndall effect that occurs when the product is injected too close to the surface of the skin. Concerns should be directed to your injector as a starting point. Good luck.
