Last night I popped to the REN head offices too preview three new and pretty impressive products - a natural alternative to retinol in a serum; a chemical free SPF 15 anti-ageing sunscreen and a skin clearing toner; all launching soon.

But, it was the brand's new marketing video that really caused a stir - a couple in a lake getting undressed and down to it (if you know what I mean). We saw everything. Here is the clean version (coincidentally, ren means clean in Swedish) but if you want to watch the, er, saucier one you can see it on YouTube here...

What do you think of the brand's new video?
