Artefill Lumps: Can CO2 Laser Help?

Artefill is injected UNDER  the skin.

The CO2 Laser, traditional or fractionated,  helps with scars WITHIN  the skin or ABOVE  the skin. Thus, it is of no value in treating your conidition.

Your condition may be improved by having the portion of the Artefill that causes the lump removed. This may necessitate more than one procedure.

I recommend that you consult a Board Certified  Plastic Surgeon, Facial Plastic Surgeon or Oculoplastic Surgeon.

Unfortunately, I doubt lasering of any kind would help. The ArteFill would have best not been used at all, let alone around your eyes.
The temptation to use something more permanent and avoid repeated injections has led many patients down a slippery road towards problems like you are having.
The problem with permanent fillers is the permanence. Whatever isn't right is hard or impossible to resolve. In addition, years later these products are known to cause infections and granulomas in some patients.

I am terribly sorry to hear of your bad experience with Artefill. I have long warned against the use of this product for the very reasons that you describe. I am not optimistic that C02 Laser resurfacing would help in your case as the Artefill is placed beneath the skin and the laser would not address this. I think you best option for the asymmetry that you describe would be a temporary filler such as Restylane or Juvederm to create better symmetry. I always advise people to carefully consider what they allow to be injected into the face and I advise against the use of permanent filler such as Artefill.
