Which skin lifting procedure is effective for the vacation season?

As I enter my 50s, skin aging is becoming increasingly noticeable, and I am very concerned that my skin is sagging and losing elasticity, especially due to the summer heat and sweat. In the past, I was able to manage my skin to some extent with moisturizers and simple home care, but lately my skin has become dry and dull, and fine wrinkles have increased, so I am considering a lifting procedure at a dermatology clinic ahead of the vacation season.

I would like to know what procedures are actually effective for improving skin elasticity. I have heard that there are methods such as high-intensity ultrasound lifting like Shurink or Ulthera, radiofrequency treatments, and thread lifting; I am curious to know the level of satisfaction for those who have actually received these treatments.

I would like to know how many sessions are needed to see noticeable changes and how long the recovery period takes. I would also like to know if it is common for the skin to lose its elasticity again, or if the effects last a long time with consistent care. It would be very helpful if you could share your experiences or advice.
