ZIIP, co-founded by facialist Melanie Simon, is perhaps best known for the ZIIP Halo — a small, computer-mouse-shaped device that treats myriad skin concerns, from wrinkles to puffiness to yes, acne. I’m 31, and genetically blessed with few wrinkles and good bone structure, so while I loved the Halo (truly, it was a cornerstone of my wedding skin prep), I almost exclusively used it to ward off breakouts. At £379.99, the Halo is far from cheap — and if you’re only interested in it for acne treatment, I might not have recommended it. But here’s where the ZIIP Dot microcurrent tool comes in.
