It feels like my skin elasticity has dropped significantly lately. What kind of treatment would be good?

Lately, whenever I look in the mirror, I feel like my skin isn't as elastic as it used to be.

In the past, I only paid attention to skin texture or dryness, but recently, my cheeks look a bit saggy, and my facial contours feel less defined than before.

Especially when I smile or make facial expressions, fine lines seem more visible than before, and when I touch my skin, it doesn't feel as firm as it used to.

My face doesn't seem to be sagging much yet, but I'm debating whether I should start managing it now or wait and see a little longer.

I looked up lifting procedures and found things like Ulthera, Thermage, and Shurink, as well as skin boosters and radio frequency treatments. There are so many types that I'm not sure what the differences are.

What treatments do people usually get for skin like mine that has lost overall elasticity and feels like it is sagging slightly?

Since this is my first time, I would like to find a method that offers natural elasticity improvement rather than a harsh procedure. Please share your experiences or recommend any treatments if you have any.
