We love straight-forward beauty products – potions that deliver exactly what they claim to, in as little time as possible. And that holds true for pretty much any product we have ever bought from REN. Our latest must-have is their new Flash Rinse 1 Minute Facial – a rich Vitamin C infused mask that gives an instant glow and the kind of babysoft skin you’d normally only achieve with exfoliation. Best of all it’s super quick to use – after massaging the mask onto your face, you dab on water to activate the mask and rinse off one minute later. Et voilà – gorgeously glowing skin.
