Do you have any good tips for maintaining skin elasticity?

Lately, whenever I look in the mirror, it feels like my skin has lost a lot of elasticity.
It seems like I have a lot more wrinkles than before, too.
I can definitely feel my skin losing elasticity as I get older.
I am currently using a moisturizing cream, retinol cream, and eye cream.
I don't have any special skin elasticity care routine, so I'm wondering how to start.
Is there a way to improve skin elasticity?
I heard that collagen is good for skin elasticity.
It would be even better if you also took care of things like inner beauty.
I'm curious about skin elasticity care methods I can do at home!
