Good ways to maintain skin elasticity?

The skin my mother gave me was white and elastic, so I looked young until I got older and didn't really think much of it.

Rather, there were aspects where we were negligent in management.

But now that I’m past the middle of 6th grade, I’m starting to get really worried.

Also, I developed wrinkles around my mouth while doing a functional home care program, and since then, whenever I look in the mirror, I often find myself wondering what I should do about it.

Botox? I was recommended it and thought about it, but I'm not keen on it. I heard it causes bruising immediately.

Please share any secrets to consistently maintaining skin elasticity!
