During the treatment, there’s a suction based applicator placed on the targeted area, which feels like a vacuum hose at a car wash. Then, the cold sensation feels like ice packs going on the skin – which can sting, tingle or burn. After 5-7 minutes, most clients go numb and relax the remaining 35-75 minutes of the treatment. When handpieces are removed, it feels like a cold foot in a hot bath. It’s uncomfortable for about 5 minutes, then goes back to feeling normal.
