I have used the Clarins one for 2 summers. It smells lovely, gives a great even light colour on my (pretty fair) skin and never seemed to streak. I ran out and bout the St TrOP daily - admittedly I did buy the dark one - basically it is a fake tan, not particularly moisturising and the tan is very dark. ALSO it has made my calves very dry . AND it doesnt smell v nice.
am using it liberally and then will buy more Clarins.
