Please recommend lots of firming creams!

I'm turning 10 the day after tomorrow... so my skin is gradually losing elasticity.

On top of that, since I'm using the heater frequently due to the season, my face has become incredibly dry, and I can really feel it losing its elasticity. As I lose weight, my cheeks are sagging and losing firmness, making my face look older and lacking in firmness.

I've been focusing only on moisturizing because I was worried about internal dryness, but now I want to pay attention to elasticity as well, so I'm looking into firming creams.

I guess I'm at the age where I want my face to feel firm and plump haha.

I was searching and the Sulwhasoo Firming Cream looked good. Has anyone tried it?

It seems like a care product focused solely on elasticity, rather than including various functional improvements.

But I don't like applying multiple products, and I'm skeptical whether using a firming cream with other improvement functions would be effective for elasticity.
