It reduces blood flow to a particular area, which can significantly reduce inflammation and swelling that causes pain, especially around a muscle, joint or tendon. It can also temporarily reduce nerve activity, which can also relieve pain.

A localized area of skin (the abdomen, a thigh, shoulder etc.) is cooled quickly (in this case to 4°C/39°F in less than 30 seconds), using a targeted spray of cold vapor. This temperature shock causes blood vessels in the underlying tissue to constrict (vasoconstriction) as a way of protecting the body’s core temperature.

As soon as the cold source is removed, the body warms the area quickly by expanding the blood vessels to around 4 times their original diameter (vasodilation). A rush of freshly oxygenated blood saturates the tissue, bringing with it, hormones, neurotransmitters, and nutrients. At the same time, unwanted by-products and waste produced from natural body processes are removed from the area to be processed by the lymphatic system.

The effect is for the localized tissue to receive all it needs to rejuvenate and restore its optimal functions: Injured muscle tissue is relieved of systemic inflammation (at the optimum time as some inflammation is useful is the healing process) and fed with all the goodness and nutrients it needs to recover faster.

Ageing and thinning skin is able to repair the basal cell layer to restore the supply of collagen, elastin and hydration to regain a smoother, tighter appearance.
