How do I restore skin elasticity?

These days, whenever I look at my skin, I just sigh and worry about the loss of elasticity.
The reflection in the mirror is like a battle against gravity, defeated miserably. My skin sags, wrinkles appear, and I look dull and lifeless.
My main goal is to restore and maintain the elasticity of my skin, which has been damaged by aging, even though it is inevitable.
I think I was a bit negligent about sun protection and hydration during my last trip.
Currently, my pores are enlarged, vertical pores are formed, and my skin texture feels rough.
Also, I don't know if it's because of the season
My facial skin feels very tight.

I think it's a difficult problem.
Skin elasticity and moisture,

This is me

I need some advice on what to do and how to do it.
