Just to give a thumbs up to Johnsons Holiday Skin......I used this instead of getting a spray tan for our wedding (even though I wasn't pregnant I didn't want to look like an Umpa lumpa and being really pale I do have this tendency).

It worked really well - give it a few days to build up. I was like Casper so it only really took only two coats. Sounds like it's much better than getting all of those nasty chemicals on you. Besides, I don't know if your skin, like your hair, will react differently to the colours so using something a bit more gentle than you can control the depth of colour a bit more may be better.
