You can put a bag over your face but that's a little dramatic. Just let your peeling continue, your skin is healing which is a good sign. Dab a small layer of coconut oil on your sunburn and it should heal quicker.
i usually lightly exfoliate the night before, and moisturise. in the morning you can cake your face if your that desperate to hide it because it will work, jus sayin. xD
peel as much as possible and then put on makeup
aloe vera :) and cover up make up
