Silk Naturals

Hello,
I am wondering what anyone out there might know about the safety of creams that contain tiny bits collagen (dehydrated I am assuming) which expand and temporarily fill in wrinkles once applied to your skin.
I notice that SN does not offer these...

Does it actually work? I've never played with collagen for skin because it's a giant molecule, and I'm not sure it would actually get in there to do anything. It's great for hair, and we do use it for that, but I'm not sure skin would take it.

It's essentially Jello- so safety wise it's not something I'd really worry about unless you're Vegan, or keep Kosher.
