Yes sunscreen works.
You just have to find a good one.
I live in Australia, and tan so dang quickly. I always wear a 50spf sunscreen if I know I'm going to be outside for a while.
Try to find cancer council endorsed ones, as they are the best. (At least, that is the case in Australia)
But as Echidna also says, many Asian beauty brands have 'whitening' products.
Or!! Embrace it! You should see my two (sometimes three) toned body! Especially in summer! Variation is natural. <3
