Maydean mecca cosmetica and adore beauty sell BB creams in a wider colour range but they are more expensive than the supermarket ones.

Even with very light skin you shouldn't be looking "white", I would say that if you are you it isn't a very good product.

If your skin is very flakey you need to be exfoliating, I use a gentle daily one whenever I'm going to use make up but also a "heavier duty" one 2-3 times a week.
