The lump could be either a small hematoma or bleed in the area of injection or lump of the injection material. In either case, it will completely disappear over time. Massage of the area at this time may help.
i am very wary of some fillers ! let me rephase that, i,m wary of the 'injectors' as unless the injector is really proficent then many things do go wrong,and my opinion is that so many fillers need top ups quite often and rather like botox,over time, it can cause a permanent 'droop'.
i personally would only go for the more permanent fillers such as Metacril or Bio-Alcamid.........again it would only be in safe hands.!
6 weeks ago I had JUVADERM injections by Dr. Alex Rifkin of the Westside Medical Spa in Westwood Los Angles. Now I have bumps that migrate around my face at will and I look like a nightmare. Much worse - the migration patterns may require serious life threatening surgery. Tell People DO NOT DO IT!
