I am one of these people that looks half-dead without make-up and would never dream of stepping outside the door without something on. Having said that, the first year we went I tried wearing normal foundation but, within an hour or so of being outside, I was seriously glowing. For the last few trips, I have used a tinted moisturiser, which means that I look like I'm wearing foundation but don't end up with it smeared all over my face shortly after leaving the room. I very rarely wear any other make-up during the day while on holiday, though - maybe a bit of lip gloss.
