A couple of observations:

He looks much younger.

He looks thinner than just a few weeks ago.

All of his facial wrinkles and crow's feet are gone.

Hair is a lighter brown.

Hair is styled differently and more fluffy.

But, it does look like him when younger, and does sound like him.

So how did they achieve this appearance change?

Maybe by using a filter on the camera, and/or changing his hair dye to a lighter shade and actual weight loss from exercise (or stress). He could also have had a face lift or a full face chemical peel or laser peel + lots of Botox.

Or, they could be using an app that morphs you into a younger image.
