Is the Shrink Universe treatment effective for skin in people in their 50s?

Hello. I am a housewife in my early 50s. Lately, whenever I look in the mirror, I feel that my jawline and cheek lines appear saggier than before, which is a major concern. People around me recommended the Shurink Universe procedure, and I am writing to inquire because I am curious about exactly how it improves skin elasticity.

I have heard that Shrink Universe uses radio frequency to stimulate the deep layers of the skin, so I would like to ask if it is safe to apply to skin in one's 50s. I would also like to know if I can expect results after a single treatment, or if multiple sessions are required. Since my skin tends to be sensitive, I am also curious if swelling or pain tends to last for a long time after the procedure.

I became even more interested after hearing from acquaintances that their jawlines looked much cleaner after receiving Shrink Universe. I am writing this post to gather information before getting a consultation. I would appreciate advice from those with experience. Thank you.
