Thank you for your question. Yes, you can have a facelift after Thermage, and three treatments six years ago are very unlikely to cause any problem. Thermage uses radiofrequency energy to heat the deeper skin layers and stimulate collagen. In some patients, especially after many or very aggressive sessions, it can leave some fibrosis (scar-like tissue) or small areas of fat loss under the skin. This can make the dissection a little more demanding, but it rarely changes the outcome in experienced hands. After six years, most of these tissue effects have settled. The risks of your facelift will mostly depend on the usual factors: your general health, blood pressure, smoking status, medications, and the surgeon's technique. Not on your previous Thermage. Make sure to tell your surgeon about the treatments during your consultation, so they can examine your skin and plan accordingly. If any fat loss is found, it can often be corrected at the same time with fat grafting. Best wishes,Dr. Safa Manav
