How it works
Fat cells are more vulnerable to cold than skin, nerves or muscle. That single asymmetry is the whole treatment. It traces back to Manstein and Anderson's 2008 paper on selective cryolysis, which reported that prolonged, controlled surface cooling selectively damaged subcutaneous fat without harming the skin above it. CR-01 works in a band of -5 to 14°C, and our manual's starting protocol sits at 1 to 4°C for 30 minutes. Selection follows from that, not from the console. Pinch the area yourself before you quote: a soft fold that lifts cleanly is the case that works, while a firm abdomen that won't tent is fat behind the muscle wall, and cold cannot reach it.
Vacuum matters as much as the cold. Drawing the fold into the cup lifts the target layer clear of deeper structures and holds it against cooling plates on both faces. Suction, infrared, temperature and time are set per handle, so two zones can run different protocols on the same client. Our manual is blunt about one setting: suction frequency stays at I throughout.
Clearance is biological, so nothing happens fast. Over the following weeks the affected adipocytes leave through normal metabolic pathways and the treated layer thins. Book the review photo at week eight, not week two. Promise next-week change and you buy refunds. Recovery in between is dull for most people, and dull is the goal. Redness, some swelling, a bruise at the cup margin and a numb patch over the treated pad are the ordinary aftermath, not signs of trouble. Late-onset soreness in the second week is the one that generates the phone call. Staff that call, brief the operator, and say all of it before the cup goes on. A warned client waits out the fortnight. An unwarned client books a complaint.
Prep is unglamorous, and it's where operator mistakes live. Cleanse, apply petroleum jelly, place the antifreeze membrane, seat the cup. Skip the membrane and you risk a cold injury. Cooling is semiconductor, backed by water and air: roughly 1800ml of distilled water at commissioning, changed about every 30 days in regular use, with the room held between 10 and 30°C.
