Can you recommend a skin elasticity ampoule?

I usually just apply skin lotion cream.
I always think it would be good to apply an ampoule, but it's also a bit of a hassle ^^;
When I see my skin sagging, I think I should apply it.
Surely it would be better to apply a skin elasticity ampoule, right?
There seem to be many different types of ampoules. Can you recommend a skin elasticity ampoule?
These days, ampoule mask packs are also coming out well... I'm wondering whether it's better to just buy a skin elasticity ampoule or a simple ampoule mask pack.
Would the skin elasticity ampoule be effective?
