Steps to take to mitigate long term damages of sunburn and skin discoloration?

Today I got a little sunburned on my back where I missed applying with my sunscreen. Nothing on the scale of blistering or discomfort; just red and warm to the touch skin. I'm very worried about skin discoloration and long term damage. Is there anything I can do to help my skin heal and mitigate the damages? This is the first time getting a burn like this as I don't burn easily and apply a lot of sunscreen.
