Is this amount of brusising normal after filler (Revolax)? (photos)

Hello! 
Bruising is common post lip filler. 
However, this is quite marked skin change, I would suggest that you need to be reviewed face to face, pretty urgently in order to exclude that there is no blockage of the blood vessel supplying the skin.

Dear UKgirl256,
Thank you for your enquiry and images.  As you mentioned bruising and swelling are a possible after this type of treatment, however black colouration can (not always) indicate vascular occlusion.  In my opinion it would be better to have this looked it by a professional, this will also put your mind at ease. 
Good luck and best wishes,
Mr Golchin

Bruising and swelling are normal after lip filler treatment. This looks like normal bruising too me which should resolve on its own over the next 7-14 days. In the future, avoiding blood thinning medications and supplements prior to treatment as well as icing prior to and after the treatment can minimize risk of bruising. A microcannula can also be used to inject the filler and this will also minimize bruising and swelling. 

This amount of bruising can occur after lip filler, it's not common but just happens occasionally. The issue of concern is ensuring that there isn't any damage to the blood flow to the area. IF you think that an area is paler than it should be or doesn't seem to have blood returning to it when pressed you should contact your Doctor immediately.
Hope this all works out for you

Dear UKgirl256, usually lip filler causes swelling as you mentioned but this black colouration might indicate vascular occlusion, which means that some of the filler were injected accidentally in the vessel, my advice is to go back (quickly) to your physician as the photos are not very clear, he will be able to check it further and act accordingly, if he feels its necrosis, he will inject you with Hayalase which dissolves the HA that is the component of the filler you had and also give you some other medicine like aspirin 300mg, nitroglycerine ointment etc.. Iam sure he will have the best knowledge handle it. if this happens it usually resolves and go back to normal if it caught early but it will take couple of weeks to do so. I hope this helps
