What are the effects and pain levels like at Suwon Dermatology's Shurink Universe?

Since I live near Suwon, I am looking into overall facial elasticity treatments at dermatology clinics in the area. I have received the regular Shurink treatment before, but I have become interested in the Shurink Universe procedure because I have heard that it is much less painful and more effective due to the rapid laser shots.

I am curious to know exactly how the effects of Shurink Universe differ compared to the existing first-generation Shurink. In particular, I would like to know if satisfaction is actually high when receiving Shurink Universe treatment to improve uneven jawlines, sagging cheeks, or double chins.

Also, since my skin is a bit sensitive and I tend to be a bit of a wimp, I am worried about how painful it will be. Is it usually manageable if I apply anesthetic cream beforehand? I would appreciate detailed advice from those who are knowledgeable about this, specifically regarding whether I can see some changes after just one session, or if I need to receive treatments periodically.
