Assuming the implant is an silicone implant placed deep in the subcutaneous tissues, it is highly unlikely that a fractional CO2 laser would hve any effect on th implant. IF the material is injected into the deep dermis, than a laser could effect the material
Laser resurfacing with any type of laser should not have an impact on a nasal implant. However, if the user of the laser goes to deep and an infection ensues this might compromise your implant otherwise you are safe to proceed. I hope this information helps.
