I'm in my early 30s; is it worth getting a lifting procedure in advance? My sagging isn't severe yet.

I am still in my early 30s, so when I mention lifting procedures, people around me react by saying it might be a bit early, while others say it is better to start for skincare before it starts sagging. I am really conflicted. When I look in the mirror, my skin doesn't look severely saggy, but compared to old photos, my jawline feels like it has slightly collapsed. It bothers me because the corners of my mouth seem to sag even more on tired days. I looked into lifting procedures like Ultherapy or Thermage, but the prices are steep and there are so many types that it is hard to justify booking an appointment. Honestly, I also wonder if I really need to undergo such an intense procedure at my age. I hear that the equipment and number of shots for lifting should be selected differently depending on skin condition. Rather than just getting a procedure because it is famous, what criteria should I use to make a decision during the consultation? Also, I am scared because I have seen reviews saying that lifting procedures actually made their faces look thinner or caused hollowing in their cheeks. I am even more worried because I don't have a lot of facial fat. I am curious to know if those who actually started lifting treatments in their early 30s were satisfied, felt definite results, or felt they could have waited a little longer. I would also appreciate your advice on which procedure I should consult for, as my goal is to prevent sagging and refine my jawline rather than address severe sagging like I am!
