Impact of Weight Loss on Ultherapy Results? (Photo)

Hi, I am a woman with mild skin laxity who has gotten Ultherapy for her neck and décolletage. I was happy with the results and am looking to do it for my face soon. However, I also have 20-30 lbs to lose and am looking to prioritize losing that soon. I’ve had success losing weight before, so hope to be successful. If I lose a significant amount of weight shortly after getting Ultherapy will that impact my quality of results? I don’t carry much weight in my face, but do have a little. Thanks!
