Cryotherapy How it works
What happens during a treatment?
The super fine applicator is held closely to the skin imperfection and liquid nitrogen sprayed onto the distorted, unhealthy tissue only. This is usually from 1-30 seconds, depending on the size and depth. The legion is then allowed to thaw and return to its natural colour. The process may be repeated in the same session if required.

Are there any side effects?
Cryotherapy is non-invasive and relatively low risk.
- There are a few side effects that may occur as a result of treatment, including:
- Temporary pigmentary changes (hypopigmentation and hyperpigmentation) in the treatment site. If this happens skin colour normally returns after a few months.
- Temporary loss of sensation (particularly in areas where nerves lie close to the surface of the skin, on fingers, wrist, area behind the ear) Reports show that normal sensitivity returns after a few months.
- Blister in the treatment area – this will be reabsorbed by the skin.
- Side effects are very rare, but please discuss any concerns you have with your clinician.
