The ZIIP Halo has long been my go-to for toning my complexion, but a conversation at Liberty's beauty counters persuaded me to finally try Medicube’s Age-R Booster Pro. It had been recommended before, but hearing someone with no connection to the brand rave about it convinced me to swap devices for a while. It feels a little uncomfortable at first, but you quickly get used to the warm, zapping sensation as you glide it over the skin. Combining microcurrent, EMS, LED therapy and electroporation, this six-in-one device promises to lift, firm, tone and boost skincare absorption. Whether it enhances absorption remains to be seen, but I do think my skin feels firmer and, dare I say it, a little more sculpted.
