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

I'm worried because my skin seems to have lost a lot of its elasticity compared to before.
My skin used to feel firm, but lately it feels saggy overall, and even when I apply makeup, it doesn't seem to adhere nicely.

I feel like the elasticity in my cheeks and jawline has decreased compared to before, so I am looking into lifting or skin firming treatments, but there are so many types that I don't know which one to get.

I am thinking about getting dermatological treatments or care instead of just doing home care, but I want to improve my skin elasticity naturally rather than having procedures that are too obvious.

For those of you who have received skin firming treatments, which procedures or treatments were most effective for you?
If there is a good management routine to start with, please recommend one!
