What are some good home care methods?

As I get older, I feel like my skin isn't as elastic as it used to be. It also feels like it's sagging more than before. I suppose skin elasticity just decreases with age...

Also, since I have combination skin, it is oily but often gets dry, so I don't know how to manage it.

Is there a way to manage skin elasticity at home? Please recommend any effective products or routines you know of~♡
