Thank you for your excellent question. ThermiSmooth treatment to the skin surrounding eyes one year after blepharoplasty is not a problem at all. In fact, it would be OK at just a few months after, as it promotes healing. With a hyaluronic acid fill, such as Restylane, ThermiSmooth can "cause" some bagginess or increased swelling, which is temporary. The fillers are hydrophilic, meaning, they tend to hold onto water and even draw water into the area, which is why everyone gets some swelling in the weeks following fillers and this is particularly obvious in the periorbital (around the eye) region, as the skin here is very thin and there is not much soft tissue between skin and bone. Usually after 3 months, this is less likely. I am not aware of any issues with ThermiSmooth causing lumpiness or impacting the long-term result, other than for the better, but short-term increases in swelling can definitely occur. I love ThermiSmooth and we get great results around the eyes! If I have a patient who wants fillers and ThermiSmooth, I would do the ThermiSmooth series first and then do the ThermiSmooth. If the patient has had fillers in the area being treated with ThermiSmooth, then I recommend waiting until 3 months after fillers for the first ThermiSmooth treatment, but I have made exceptions to that rule and have not experienced problems doing that.
