The Cryopen uses disposable cartridges of liquefied Nitrous Oxide to deliver quick, effective Cryotherapy treatments to benign skin lesions. The nitrous oxide destroys the skin’s tissue by freezing the intercellular fluid which forms ice shards and crystals that rupture the cells’ membranes, destroying the cells.

CryoPen delivers Nitrous Oxide directly onto the lesion and not the healthy surrounding tissue. Thus it can safely treat lesions on the face and around the delicate eye area. With a penetration rate of 1mm per 5 seconds and the ability to penetrate to a depth of 5mm, the pen provides fast and effective treatments.


  • Pinpoint accuracy: treats lesions from 1mm to 10mm in size
  • Safely treats lesions on face and close to the eyes
  • No downtime or risk of scarring.
  • Painless treatment with no anaesthetic required
  • Effective: treats the lesion without affecting the healthy surrounding tissue, which means no follow up care is needed
  • Fast treatments: treats 2mm lesions in 10 seconds

How permanent is the cure?

Cryotherapy offers a permanent removal for most skin lesions. Some lesions may be harder to remove than others. In more delicate places eg the eye area, a shorter freeze time with a repeat procedure may be required to get a safe final result whilst ensuring little damage to the surrounding skin. A deeper lesion eg a verruca or a wart may take several treatments to get good results

Risks & side effects

CryoPen therapy has been established to be very safe. However, the following side effects may occur:

  • Mild stinging following the procedure, which usually settles after a few hours.
  • Sores and blisters – Can rarely form where the skin lesion was treated. Often a scab will form in the following days and fall off thereafter. This is common where deep freezing is used.
  • Both hyperpigmentation (darkening of the skin) and hypopigmentation (lightening of the skin) may occur temporarily after cryotherapy. Both generally last for a maximum of a few months. Pigment change is more common in darker skin types.
What are the treatment costs?

It is very difficult to state a fixed price as it will depend on the size, depth, quantity and area of the skin lesion being treated.

Prices typically start from £50 with discounted prices being available for multiple lesions/areas.
