Niuk roll-ons are -18°C local cryotherapy devices that combine 3 actions in 1: controlled cold, mechanical massage, and targeted serum application. They promote recovery and decongestion, and have already been adopted by athletes and healthcare professionals.
Cold soothes, massage relaxes, and serum prolongs the effect. Niuk roll-ons combine these three actions in one simple gesture, applicable to a specific area in just a few seconds.
The medical-grade stainless steel ball conducts cold and, as it rolls over the skin, provides a precise massage. An internal reservoir calibrated to -18°C supplies it throughout the application. Depending on the version, a serum is dispensed as the ball rolls.
A documented cryostimulation technology
An observational study conducted in physiotherapy clinics on 170 patients reported encouraging results regarding pain, mobility, and inflammatory signs. Niuk is now a Class I medical device, with 11 patents filed since 2023.
Frequently asked questions about our cryotherapy roll-ons
It is the application of intense but controlled cold to a specific area of the body. Unlike a cryotherapy chamber or a cold bath, it acts precisely on the treated area. Niuk roll-ons deliver this cold via a metal ball that rolls over the skin, supplied by an internal cold reservoir.
The Niuk Body Pro, with a 35 mm ball, covers large areas: back, lower back, shoulders, thighs, calves.
The NiukSport, with a 30 mm ball, supports preparation and recovery in the field: grip adapted to physical exertion, cooling cap, use on strained muscles.
The Niuk Essentiel, with a 25 mm ball, works on medium and targeted areas, such as the cervical spine or joints.
The Niuk Précision, with a 16 mm ball, is used on fine and delicate areas: eye contours, face, precise points.
Niuk roll-ons work at -18°C, the temperature of a standard home freezer. The PCM in the reservoir is calibrated to capture this cold and release it gradually to the ball. No special equipment is therefore necessary: simply place the roll-on in the freezer. The cold produced is intense yet controlled.
Cold causes vasoconstriction followed by reflex vasodilation. The rolling massage adds mechanical stimulation of the tissues. Both act simultaneously, in a single motion, and the serum is diffused as the roller passes over.
An ice pack stays stationary on the skin and loses its cold in a few minutes. The Niuk roll-on combines two actions: the stainless steel ball conducts cold and, as it rolls, provides a mechanical massage. Its PCM reservoir continues to supply the ball with cold throughout use, whereas a classic metal roller warms up quickly.
