For those in their mid-30s, is there an elasticity ampoule that you repurchase and use?

Lately, I feel like my skin has become less elastic, so I sigh every time I look in the mirror. I can see that the wrinkles around my eyes and nasolabial folds are getting deeper, so I think I need to take care of them a little.

Right now, I'm just using the moisture line, but I think it's time to mix in some functional products! Are there any older or younger siblings who have really found this amazing ampoule effective and stock up on two or three bottles?

I'd love to hear recommendations for genuine, "self-made" items, not just ads. Let's share the good stuff! Please leave a comment!
