CryoTherapy: FactFile

Cryotherapy is the selective destruction of lesions by causing cryogenic cell death (killing cells with extreme temperatures). This preserves the tissue matrix which is relatively cold resistant, and therefore allows full cosmetic healing with minimal risk of scarring. Our most important mission is to help you love the skin you’re in. But sometimes this can be difficult with the arrival of unwanted marks, milia, and skin tags. Gone are the days that these were a fact of life and you had to love yourself ‘warts and all’. With pioneering, fast, safe, and effective cryotherapy treatments using CryoPen’s state-of-the-art technology, you can finally give unwanted marks the cold shoulder.  

The treatment is suitable for a range of cosmetic procedures, most of which have been phased out by GPs. These include: 

  • Skin tags 
  • Solar lentigo 
  • Age spots 
  • Milia 
  • Warts 
  • Cherry angioma 
  • Viral verrucae 
How does it work?  

Cryopen emits a fine jet of nitrous oxide under high pressure to allow the clinician to work with pinpoint accuracy. This destroys the tissue by freezing the cellular fluid, which then forms crystallised ice, which in turn destroys the cell. The technique ensures no healthy cells are damaged in any way, leaving the rest of your skin flawless, and rendering the technology safe and efficient.  

A freeze-thaw-freeze approach is often used: 

Freeze – The applicator is held as close as possible to the skin lesion and moved quickly towards it and away from it.  This could be from 1-30 seconds depending on the size and depth of the lesion. 

Thaw – After the first freeze treatment, the tissue is left to thaw for about 30 seconds. 

Freeze – After the thaw a second freeze is completed.  The tissue will freeze faster than the first time. 


How many treatments will I need?  

One treatment is all it takes to ice out your unwanted skin blemishes. The best thing about this treatment is that it only lasts from 5 to 30 seconds, meaning the procedure takes no time at all. The procedure is only about as painful as tweezing a stray eyebrow hair.  

After Treatment  

There may be a stinging sensation on the skin, when the nitrous oxide reaches the bottom of the area. This may last for a few minutes following the treatment. Occasionally a blister may form and persist for a few hours. Over the following days a scab may form and the lesion become a little red and angry looking, this discolouration will generally resolve over 1-6 weeks, leaving absolutely no trace of the treatment or the blemish. It is very important not to pick any scabs as this might lead to scarring. 

Cryotherapy is relatively low risk although there can be some hyperpigmentation side effects. This is light or dark areas appearing after the treatment – if this does happen the skin usually returns to normal colour after a few months.  


What is the cost?  

This treatment does require a consultation beforehand, which is free of charge. This is so our medically qualified practitioner can determine whether you would be suitable for treatment, and can talk through the procedure with you, including aftercare and the cost to make sure you look and feel your best.  

The procedure is £50 per session, and sometimes more than 1 session might be needed depending on the lesion. For some mole treatments, a doctor’s note may be required.  


So get in touch if you want to know more about cryotherapy, or have any questions about your particular skin issue.
