The usual allergic reaction to Artefill would be a pink to red, swollen bump similar to an inflamed pimple. It may or may not itch. It may show up after 1-3 days as an immediated reaction or it may be delayed and show up a few weeks later. It is the collagen that the plexiglass beads of artefill is suspended in that you are being tested for. There are no allergies to the beads themselves though. The beads are so tiny that you can't see them and they are permanent.
Artefill is usually injected in 2-3 sessions. If you do develop an allergy then it may last from weeks to many months. There are cortisone injections or Prednisone pills that help the reaction resolve. Rare reactions would include flu-like symptoms but you would still see the red pimple in any case.
