Does calamine lotion help heal sunburns?

No...use aloe vera, milk or vinegar. Milk or vinegar just rub onto the skin with a cotton ball and dont forget to shower regularly so you dont end up smelling sour :) they really work though, trust me. Vinegar if applied right away will make it painless and it will make you tan rather than bright pink and the lactic acid in milk just helps soothe the pain.
