It's the largest organ in the body.
If you get a little sliver, the skin can absorb it.
If you get a big sliver, the skin produces fluid around the foreign body and forces it to the top of the skin to be removed.
It constantly regenerates itself. (On average the top surface renews every month!)
It can bond together after even severe lacerations!
It can register temperatures and even emotions.
It's a great protector.
And on and on....
Instead of worrying about the color and the wrinkles on our skin, I think we should just joy in how miraculous it is!
