Ulthera works best for tightening of the neck and jowls. Intense Pulsed light is great for the pigment spots. And there are many lasers which work well for the wrinkling. Thermage should help with the wrinkles, but you might also want to consider fractionated CO2 or a new technology such as Infini which is micro-needling with radiofrequency.
In my opinion, Ultherapy is a far superior treatment to Thermage for tightening, lifting, and toning loose skin. In, fact it is the only FDA-approved treatment for doing so. If your main concern is with wrinkles and you are determined to be an appropriate candidate then I would recommend Ultherapy. However, neither Ultherapy or Thermage treat age spots or large pores. There are other procedures which will treat those conditions. I suggest you schedule an in-person consultation with a board certified physician who can evaluate all of your concerns and come up with a personalized treatment plan for you. Best of luck.
