As with all injectable wrinkle fillers, you can expect swelling and bruising in the treatment area.  Swelling usually goes away completely after 10 days but if you had Bellafill under your eyes it, in rare cases, can last up to 3 months.  Sometimes there is bruising that typically disappears in seven days but can last 3 weeks before it is completely gone.  If you have bruising after a Bellafill treatment it is fine to use any cover up makeup.  It is very common to have some slight redness and increased sensitivity at some or all injection sites.  Two rare side effects of all dermal fillers may be lumps and granulomas.  With Bellafill, true granulomas are extremely rare.  Usually what is seen are lumps.  The original collagen injections for wrinkles almost always made lumps that dissipated at 3 months.  Since Bellafill is mostly collagen, it is not unusual for Bellafill to make lumps that you can feel.  These lumps almost always go away by 3 months and you are very rarely able to see them.  If they can be seen, then Dr. Somenek can treat these to make them go away.
