My friend gave me a bag of St Tropez stuff at the weekend. It's all unopened, but about a year old. Just had a bit of a go on the whipped bronze instant self tanning mousse, but it's bright blue? ! It's supposed to be dark brown isn't it? I've googled to see if this is what happens when it goes off, but to no avail. It has gone off though hasn't it? It's made my leg a sort of green colour!
