Many different superficial skin lesions can be treated with cryotherapy including viral warts, seborrhoeic keratosis, actinic keratosis and other benign lesions. It
is essential that a correct diagnosis is made before treatment as we do not treat any cancerous lesions as these are more appropriately managed and followed up on the NHS. If a lesion looks
suspicious of skin cancer, you will be advised to seek advice from your General Practitioner.
Due to the risk of damage to the surrounding area, treatments in close proximity to important structures such as the eye are avoided. Treatment can take place on
the face, scalp or body depending on the type of skin lesion. It is possible to treat several areas in a single session
CryoPen® is a medical procedure which involves the application of nitrous oxide gas under high pressure to the skin where the
unwanted lesions are frozen and destroyed. The tip of the Cryopen® may reach as low as -89oC although the aim is to create a thermal shock to the tissue which involves a rapid drop of temperature. This has the
effect of crystallising the contents of the body cells leading to destruction of the skin lesion. The duration of the treatment is dependent on the size and nature of the lesion, but generally
each lesion just takes a matter of seconds. It is usual to see a frost or ice-field appear on the top of the lesion during treatment. A ‘freeze-thaw-freeze’ approach is often used when
the lesion is frozen, allowed to defrost for a few seconds and then a second treatment applied. Although it is best to try to leave the treated area uncovered, a plaster or simple dressing may
be applied if it is in an area which may lead to rubbing and aggravation.
A follow up visit is recommended after 2-4 weeks to assess response to treatment and further application if required. Over the following days, a scab will often
form and the lesion may become a little red and angry looking. This will usually resolve over 1-4 weeks and the area remaining will often return to normal, although it is possible to develop a
small area of scarring or change in skin colour. Lesions treated on the legs often take a little more time to heal. It is important not to pick at the scab as this may lead to
Thread veins & cherry angiomas
Electrolysis is a safe and effective treatment used
for the removal of sebaceous cysts, milia, skin tags, blood spots and thread veins. Results are
instantaneous in many cases. Electrolysis involves the insertion of a very fine, disposable, sterile probe (the same diameter as the hair) into the skin, which cauterises the vessel. Local
anaesthetic is applied prior to treatment.
