The term ‘cryo-stimulation’ literally means ‘stimulation using low temperature’ (“Cryo” from the Latinised form of Greek, “kryos” for “icy cold” + “stimulation” – encouragement of something to make it develop or become more active) and is used as a modality to stimulate a beneficial physiological response from the body.

TruCryo uses the cooling power of carbon dioxide (CO2) – the same as the contents of the fire extinguishers seen on office and clinic walls. The CO2 is in liquid form in the cylinder and, as it leaves, expands and cools to a very chilly -78oC (-108oF), providing a stream of cooling vapour which is applied to the skin.

The technology allows a localised area of skin (the abdomen, a thigh, shoulder etc.) to be cooled quickly from around 35oC/95oF to 4oC/39oF in less than 30 seconds, using a targeted spray of cold vapour. This temperature shock causes blood vessels in the underlying tissue to constrict (vasoconstriction) as a way of protecting the body’s core temperature.

​

How does it work?

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 localised tissue to receive all it needs to rejuvenate and restore its optimal functions:

• Injured muscle tissue is relieved of inflammation (at the optimum time as some inflammation is useful in the healing process) and fed with all the goodness and nutrients they need 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

• Fat tissue breaks down and is eliminated from the body, while other surrounding tissues are not damaged.
