The treatment is short, 90seconds to 5minutes, a steady stream of supercooled nitrogen vapour, which very quickly and painlessly reduces the temperature of the skin and underlying tissues, the affected areas are precisely targeted.
Cryotherapy applied to living tissue has 3 main effects:
- Analgesia - cryotherapy can slow down the electrical impulses from the injury site that tells the body that it is in pain.
- Hypometabolism - cryotherapy reduces metabolic rate, decreasing the amount of oxygen and glucose that the cells need to survive, this can help prevent the affects of oxygen deprivation.
- Vasoconstriction - narrowing of the blood vessels, reducing blood flow helping to prevent excess bleeding and oedema.
