Is this necrosis from lip filler injections? (Photos)

Bruising is very common in filler application... There are very small vessels that a surgeon cannot predict to be there and with the injection and product application can be damaged. In the lip there is a rich capillary network... The lip is a well irrigated anatomic unit, thus bruising is more likely. Based on the images its just bruising, necrosis is less likely and very rare in the lip. Please be patient and wait at least 2 week until inflammation and bruising are resolved to see the definite result. Thank you very much, hope this help you on your question

This doesn't look like a vascular occlusion, But i would follow up with your injector at the 2 week mark as it may be some bumps due to overfill of the product. To help with the bruising consider taking some arnica pills or eating a pineapple(the bromelain in it helps with bruising). Also avoid any alcohol, omegas or advil, as these agents will prolong bruising

This does seem to be significant bruising coupled with superficial injection of filler. I would contact your surgeon for assessment so he/she can examine the area appropriately. Bruising of this extent is rare now we use cannulas in this area.
