“I’ve been a ZIIP devotee ever since getting a facial from founder Melanie Simon several years ago; I’ll never forget seeing my skin visibly lifted and brighter after one session with her, and continued to use the brand’s hero product, the Halo, to help tone facial muscles, address uneven tone, and treat breakouts — that’s right, it does it all, thanks to the power of nano- and microcurrent. ZIIP’s latest device, the Dot, brings the same technology in a palm-sized, acne-focused tool that retails for half of the Halo. Within weeks of regular use (I alternate every other day), I noticed fewer acne and clogged pores, and brighter, more radiant skin to boot. (I’ve found that it’s especially effective at targeting cystic acne, which is notoriously hard to treat with topicals alone.) All in all, if you’re looking to boost your acne skincare routine, I can’t think of a better addition to your arsenal.” — Karina Hoshikawa, senior beauty writer.
