According to founders Robert Calcraft and Antony Buck everything in the minimalist Ren (Swedish for clean) must have: the "right" 1) Ingredients; 2) Science; 3) Product Experience; 4) Environmental Impact and 5) Attitude. We like that. Sienna Miller, Kate Moss, Uma Thurman and Jade Jagger are all fans. For the face: The Mayblossom and Blue Cypress Facial Wash. For the body: The award-winning (delicious) Morrocan Rose Otto Body Wash. These peoples reckon they're all about "clean" skincare. (Which we're pretty happy about considering their specialty is cleansers.)
