How to get darker without sunburn?

Glad that my rosacea is now under control but the bad news is my face goes ghostly white which makes me look ill (probably because I stayed away from sun for more than half a year). I dont like this pale! People begins to make fun of me saying something like "OMG Halloween is coming?" I never feel this bad as being a fair skin asian girl :(

I really want to go under the sun to tan my skin a bit or get a healthier look. Anyone knows how to get darker without burning the skin? Please help :(
