Is there a big difference between the effects of Shrink Universe and the original Shrink?

As I get older, seeing my jawline sag stresses me out every time I look in the mirror, so I decided to get a lifting procedure.

Lately, I've become interested in the upgraded Shrink Universe effect compared to the previous version because it is said to be less painful and more precise. I remember having a hard time with the pain when I received a regular Shrink treatment in the past, but I like that the new Shrink Universe effect can deliver energy meticulously even to curved areas thanks to the Ultra Booster handpiece.

However, the most important thing is actually visible change. I am curious whether the effects of Shurink Universe usually appear immediately after the procedure, or if they are felt only after enough time has passed for collagen to regenerate. I am planning to get about 300 shots; will I be able to see the effects of Shurink Universe with this amount? Although there may be individual differences, I would appreciate your advice on how many sessions are typically required to maximize the effects of Shurink Universe and maintain them for a long time.
