How do I care for a tanned face?

My son came home yesterday morning completely sunburned.

I went out this morning with high hopes of playing soccer (I was excited because it was vacation)

When I came in, I noticed that the area around my eyes, my cheeks, and the back of my neck were all sunburned.

Since he woke up earlier than me and went out,

I didn't even pack sunscreen, so this happened...

How should I take care of a tanned face?
