Shrink Universe for facial line shaping

Lately, every time I look in the mirror, I feel like my cheeks are sagging, and my double chin is really bothering me. I can clearly see the loss of elasticity as I get older, so I thought I should get a lifting treatment. Many people around me have been recommending Shurink Universe, saying it is very effective these days.

However, I've read reviews saying that the effectiveness varies quite significantly depending on the number of shots and intensity. I'm curious if the director personally designs the number of Shurink Universe shots based on my face shape and skin thickness. I think it would be better to have the dosage tailored to my degree of sagging rather than just getting a lot of shots blindly. Can I see noticeable line-shaping effects with Shurink Universe alone?
