I watched The View from Monday and Ralph Macchio was on. He was in all the Karate Kid movies. He is 60. I am 60. He looks so young. He could pass as my son, and I'm a young looking 60. 
He doesn't age. It is amazing. They showed a clip from the TV show he's on Cobra Kai, and in the headband from The Karate Kid, he looks the just about the same.
I want what he uses. At 80, he'll look 50.
