What are the good ingredients for skin elasticity?

Another year is passing by. It's just like getting a year older again.

Every time I look in the mirror, it feels like my skin is aging along with me day by day; my skin elasticity is decreasing. I have more wrinkles, age spots, and lots of blemishes.

So now I don't want to look in the mirror anymore.

I looked for cosmetics for this kind of skin elasticity

There are some that contain retinol, and there are also many collagen products.

What is the difference between retinol and collagen?

I've heard a lot about collagen. But I don't know much about retinol.

Which is better for skin elasticity? Are there any products that contain both?

Would there be a synergistic effect if I used both retinol and collagen together?

If there are any effective products containing ingredients for skin elasticity that you think are the real deal, please recommend them.
