Tanning is sooooo bad for you, I would never go on a sun bed. My Mum used to have her own in the 80s and was a total sun worshiper too, then yup, not atall surprisingly she got skin cancer 2 years ago. She's ok now but we wont know for another 4 years if it is totally gone and wont be coming back. It also means I'm more likely to get it, and if you have lots of moles then you're more likely to get it too. Even when I go on holiday or if we ever have a sunny summer I always wear sun lotion and build up a tan very gradually.
St Tropez is great, but expensive, I love Johnsons Holiday Skin, its a miosturiser with a bit of self tan in, it never streaks cos it builds the tan up over a few days of using it, and my skin is so healthy and glowing, plus it costs less than a fiver!
