There are so many types of lifting procedures that I don't know which one to get.

I have started to become increasingly concerned about my sagging skin, so I am looking into lifting procedures. However, the more I search, the more confused I find that there are so many types available.

I see that there are ultrasound, thread, and radiofrequency lifting methods. I am unsure if the type of procedure depends on the degree of sagging or skin condition, or if the choice is based on the desired effect. I have also heard that different lifting procedures can be combined; is that something that can be confirmed during a consultation?
