Exfoliation is a key step in achieving the best results from your fake tan.

It's something we do our best to do every time (though we're guilty of sometimes putting new tan over old tan) but the way we've been doing it is all wrong, apparently. Jimmy Coco counts the Kardashian and Jenner sisters as clients, as well as Ashley Graham, Gigi Hadid and Heidi Klum. He's a big believer in scrubbing away old tan and skin cells before applying a fresh layer of fake tan - but he says dry exfoliating is the way to go. "Scrubs and soaps create a barrier on your skin that creates uneven, streaky, blotchy results," he told Refinery29. "Your tan can't get in and do its job if you have any residue on the skin. "I have always told my clients that you need to exfoliate after the shower." This removes any residue from whatever products you used in the shower as well as the top layer of skin. It sounds kind of scratchy and a bit sore but Jimmy has created a special mitt for this purpose. One side is a normal foam mitt for applying fake tan, the other a bamboo scrubber to lift old tan and skin cells. It looks like you can only pick up his Buff 'N' Tan Mitt in the US for now but using a soft washcloth, a loofah or a body brush will also do the job, he says.
