As a pale person who has on many occasions walked rode or ran down various streets and places completely naked (proof on my youtube) I know my sun protection. I find creams work better then sprays, SPF means absolutely nothing, and if you already have a burn, there isn't much you can do. Aloe is the best option but its still not a good option compared to not having been burned in the first place (you already had your cells burst open from the radiation damage so you just have to basically heal it). If you grow your own aloe you fillet it like a fish. I like this guy's video:

except I don't like the concept of eating it.
Just make sure to slather yourself in sunblock whenever you will be in the sun and don't forget to do that.
Also, if you cover your whole body in sunblock when you go outside naked it gives you that slightly shiny appearance that bodybuilders try to get. That's another cool perk.
