★★★☆☆Some of the statistics around the device — 80 per cent of users reported noticeably firmer skin after six weeks — are compelling. Others — “up to” 12 per cent noted visibly reduced cellulite after four weeks — are considerably less so. What it probably is going to do, if used diligently, is make your skin feel firmer and brighter. The marketing is keen to stress it offers results in “just” 10 minutes a day, but that doesn’t sound all that quick. It’s more achievable if you think about how much time we spend staring at a screen.
