I hit my face 4 months after filler. Did it move or deform my filler?

I would not expect a hit to the face, 4 months after placement of a filler under the eyes, to have any effect on the filler.  The hit should not move or deform the filler.  

I'm sorry to hear you took a hit, but thankfully it shouldn't have affected the results of your dermal filler. The fillers under your eyes shouldn't be moved or disrupted by a minor trauma. The results of your fillers should have been fully set after two weeks at the longest. If you're noticing a change in the area where your fillers were applied, you should return to your cosmetic surgeon. It could just be the natural degradation of the fillers over time.

Thankyou for your question. You do not need to be concerned after  months. The filler is truly integrated at this time  ( ie set)  Nothing will have happened to the fillerGood luck

After 4 months the filler should be “set” or anchored in the skin where it lives.  It is unlikely to deform or or move despite a blow or forceful facial injury.  If it a hylauronic acid filler it can retain some the swelling that occurs with the injury.  So, it may look a bit “puffy” even after the injury has healed and the swelling subsides. The HA molecules like to hold onto that water, but this will go away and things will go back to normal.  No harm done.
Hope this all makes sense and is useful for you,
Dr. Amy

Great question thanks!  Most fillers are incorporated into your tissue at that point so it would be unlikely that a hit in the face would distort the filler or move the filler.  Thanks again for your question.

Take care,

Hi,
thank you for your question. Generally, the first two weeks post
treatment is when slight changes can occur. After this time frame,
the filler is usually settled and you cannot cause any
damage/deformation to the area filled. Don't hesitate to contact your
injector with any concerns. All the best, Dr Campey.
