Is It Safe to Have Deep FX on Face with Permanent Filler?

There is no clinical data to support the safety or non-safety of DeepFx with a permanent filler. While Deep Fx is not likely to penetrate to the level where the filler is, there have been occasional reports of inflammation from silicone injections after laser resurfacing. So unfortunately there is no data to adequately answer your question, and as a physician I would not feel comfortable to do that treatment.
