Which is better for skin elasticity, retinol or collagen?

I heard this retinol serum was good at Daiso yesterday, so I bought it for 5,000 won.

So I'm curious.

I became curious about which is more effective among skincare ingredients: retinol or collagen.

Between retinol, known for wrinkle reduction and regeneration, and collagen, which provides hydration and firmness, what is the actual difference in improving skin elasticity?

I’ve heard that the absorption method and longevity differ, so I’m curious about your experience or the evidence regarding which ingredient is more helpful for maintaining skin elasticity in the long run.

I would appreciate it if those with experience could leave a comment.
