What treatment is good for skin elasticity?

Lately, I've been worried because every time I look in the mirror, I notice sagging skin.

I'm considering a procedure, especially since my skin feels more elastic than before. These days, there are so many procedures that claim to improve skin elasticity, but I'm not sure which method is most effective.

I'm also worried about whether skin elasticity improvement treatment will be suitable for my skin type. I think it would be helpful to hear the opinions of experienced or expert people to help me decide.
