Ulthera vs. Thermage, choosing a lifting procedure is difficult.

I want to get a lifting procedure, but I'm really confused about whether Ulthera or Thermage is better. Many people around me recommend both treatments, saying they are definitely effective, but I was disappointed because the results weren't as good as I expected when I actually tried them.

I am even more concerned because I have heard stories of people spending a lot of money on procedures only to see minimal results, or even experience side effects like sunken cheeks or a peanut-shaped face. While it is said that results vary depending on individual skin condition and age, what criteria should I use to choose a procedure?

I understand that Ultherapy stimulates the deep layers of the skin to improve elasticity, while Thermage uses radio frequency to tighten the skin surface and dermis, but I am not entirely sure what the actual differences are. I am also curious about how long the effects last after the procedure and whether maintenance care is necessary.

If you, like me, are concerned about sagging facial lines and loss of elasticity, I would like to hear opinions from those who have experienced the procedures on which one to consider first: Ulthera or Thermage. If you have actually received the treatments, it would be very helpful if you could share your satisfaction levels and whether or not you experienced any side effects.
