Here at Caltrology Electrolysis, we use the most advanced electrolysis machines available on the market, and they are being operated by licensed and board-certified staff. Our team uses both the Apilus Senior 3G, which is the #1- sold electrolysis machine in the world, as well as the Apilus XCell, which utilizes the most advanced and efficient technology on the market. The Apilus XCell machine uses 27.12 MHz ultrafast radio frequency. This frequency is up to six times faster than other hair removal devices, and the treatment is performed so quickly that the sensation is less noticeable. The current used is lightning quick from between 100th to 1,000th of a second.
