I have a question about the Shurink Universe to tighten sagging cheeks and double chin lines!

I am in my late twenties and have entered my thirties, and I have started to feel my facial skin sagging little by little. I am particularly stressed about the deep cheek fat around my mouth and the double chin under my jaw, which resembles bulldog cheeks. Whenever I take a selfie, my lower face line looks heavy and dull, so my impression isn't the same as before, and my face feels much bigger. While looking for a tightening laser that can firmly pull and fix sagging lines with minimal pain, I learned about the recently upgraded Shurink Universe procedure and am seeking advice.

I heard that the principle behind this is that it uses high-intensity focused ultrasound to deliver energy deep into the fascial layer of the skin for a lifting effect. I also heard that unlike the previous version, the Shurink Universe procedure features subdivided tip types, such as line and dot types. I am curious if it causes a tightening effect on my lower face, which tends to be a bit fuller and sagging, like mine. For those who have received this treatment, did you really see a noticeable effect in defining your facial lines?

I am worried about the level of bone-shaking or tingling pain during the procedure, and whether the swelling will last a long time and interfere with my work and daily life. If there are any experienced users who have definitely seen their jawlines defined justify the cost, I would really appreciate your honest advice or answers regarding the Shurink Universe laser. Do you all get Shurink Universe treatments regularly bundled with square jaw injections? Thank you in advance for your comments!
