The most common questions

  • Cryotherapy can be practiced by licensed practitioners only. Please note that laws and restrictions who may practice cryotherapy may differ between countries and states.
  • A treatment with a CryoIQ device can easily be incorporated in a busy practice as no pre- or post-treatment care is needed. In general, a treatment with cryosurgery/cryotherapy shouldn’t last more than 20 seconds, and sometimes only for a few seconds seconds, all depending on the kind of lesion.
  • The morphology of a lesion determines the freezing time. Often a skin disorder can be removed in one treatment, whereas a freeze-thaw-freeze cycle in such treatment is a standard within cryosurgery/cryotherapy. A follow-up visit can be scheduled in a time frame of 2-3 weeks after the treatment in order to see the results.
  • The standard spray freezing tip provides immediate and direct coldness to the skin. The contact tip needs to be cooled before being applied to the skin. The contact freezing will give a more concentrated freezing picture compared with spray freezing.
  • With the use of nitrous oxide as a cryogen the risk of scarring is very limited or non-existent as the penetration depth is at most 4 mm. The freezing temperature of nitrous oxide is -89°C/-128°F and as such considerably less as the boiling point of liquid nitrogen -196°C/-346°F. The latter is well known for the risk of scars and blisters. Cryotherapy is known for its excellent aesthetic results.
  • A treatment which has been done over a too long duration or too deeply may cause a blister. The latter can be covered with a band aid – do not puncture the blister.
  • CryoIQ offers a gas cartridge size of 25 gram filled with nitrous oxide. The diameter of the applicator determines the amount of gas sprayed per second to cover the surface of the lesion as the thickness of the lesion determines the seconds of freezing time. For instance, a superficial lesion of 1 mm thickness may take 3-5 seconds of freeze whereas a large wart may need up to 20 seconds of freeze. In general, the device with a standard applicator attached you will get approximate 540 seconds freezing time.
  • In average the shelf life of the cartridges is three years from production date. After one year of storage, the cartridges will have had a gas loss of below 1 gram per year due to technical reasons. The cartridges are considered consumer commodities and as such storage is simple. They have to be stored at room temperature +21°C.
  • Our cartridges have a built-in filter and are filled with medical grade gas. Some manufacturers use technical gas for this application which not is recommended for medical treatments.
  • The warranty period is 12 months, however after registration of the product we offer 24 months. To extend the warranty, please visit our warranty registration page and fill out the form.
  • The only type of warts that should be debrided are foot warts. This should be done to pin point bleeding. Read the IFU for more information.
  • The disposal of the gas cartridge and all other parts of the device shall be conducted in accordance with local requirements. An empty gas cartridge may be disposed of as scrap metal.
