Neuskin cryotherapy refers to the use of thermal-shock technology with the Neuskin™ device, which combines rapid warming and cooling to target and reduce fat cells through a process called apoptosis for body contouring, and also improves skin appearance by stimulating collagen and tightening pores through treatments like Cryotone®. The treatment is non-invasive and can be used on various areas like the face, neck, abdomen, and thighs, with results becoming noticeable over a few weeks as the body flushes out disrupted fat cells.
