Does Shrink Universe 300 Shots effectively refine the jawline without sunken cheeks?

My double chin and jawline have become blurred, so I am considering getting the cost-effective Shurink Universe treatment. Since I don't have very chubby cheeks, I am worried that my cheeks might hollow out or the area under my cheekbones might sink in after the procedure. I've heard that many people get the treatment combined with the Ultra MP mode and a pen-type tip; will I be able to feel a difference in my lines with just around 300 shots?

If anyone has successfully lifted their jawline cleanly with Shurink Universe without any hollowing in their cheeks, please share the number of shots or treatment tips in the comments!
