This cream is for wrinkles!

So I am getting ready to go out and I put my face cream on and dear five yr old daughter reaches for it. I take it from her.
Here is how the rest of that went:

Me: This cream is for grown-ups.
Her: Why is it just for grown-ups?
Me: It's to help hide wrinkles.
Her: What does a wrinkle look like?
Me: Like this, see? When I smile? You can see the wrinkles.
Her: You don't need to smile mom, I can see them even when you don't smile.
