Will the more shots of Shrink Universe, the better the effect?

I was shocked when I saw a profile photo taken at an acquaintance's wedding recently; my jawline didn't look the same as before, and my double chin was very prominent. I hurriedly tried using a home massager, but it seemed insufficient to keep up with the rate at which my skin elasticity was declining. While looking into proper lifting treatments, I came across Shurink Universe.

I am particularly sensitive to pain, so I hesitated to try conventional lifting devices for fear of it being painful. However, I became interested in the Shurink Universe because I heard the procedure is faster and the pain is significantly reduced. For someone like me whose main concerns are sagging cheeks and tightening the double chin line, how many shots would typically be needed to feel the effects? I am also curious if the Ultra Mode and Booster Mode are used together.

Please let me know if I can return to work immediately after the procedure since there is not much swelling or redness, and also provide information on the costs for the current Shurink Universe 300 shots and 600 shots.
