How many times is the recommended number of Shrink Universe treatments?

Now that I've entered my 30s, I really understand what elasticity is...

I used to be fine even after staying up all night, but these days when I take photos, my jawline isn't the same as before, and my face feels saggy overall.

So, while looking into lifting procedures, I came across Shurink Universe, and it seemed like a lot of people were getting it.

But I'm curious, how many sessions of Shrink Universe do you generally think are needed to see good results? I'm confused because when I look at reviews, some people say they were satisfied after just one session, while others say you need to receive it consistently to maintain the effects.

I am also curious about the pain. Since I tend to be sensitive to pain, I would like to know if the Shurink Universe treatment is very painful.

Also, I am curious if you can actually feel your facial contours being refined after receiving the Shrink Universe treatment. Please share reviews from those who have actually received the treatment, not just promotional photos. I would also like to hear about the satisfaction level relative to the cost.
