Most warts and benign lesions are targeted at -30 to -50C. The technology behind cryosurgery involves using liquid nitrogen at temperatures between -50C to -196C. At -50C, patients do not experience much pain or discomfort, however the current technology behind -50C results in temperatures which fluctuate, which can give a variable or ineffective treatment result. The alternative is liquid nitrogen at -196C which may be uncomfortable for patients to tolerate.

At our Cryosurgery clinic in Singapore, we employ a constant temperature of -89C, with an average application of time of 12 seconds, freezing the target tissue to a depth of 3 mm, by a diameter of 10 mm. This is better tolerated in terms of discomfort and achieves a more constant therapeutic outcome.

The top layer peels off within 1-3 weeks and takes all or part of the original growth with it.

If you have decided on visiting us, make an appointment with us today and our doctors will assess the skin condition and make a diagnosis.

Before commencing any treatment, we would also go through with you the conditions which may make cryosurgery unsuitable for you. Conditions such as an autoimmune disease, immune suppression medication, skin lesions in sensitive areas (eyes, near blood vessels, nasal folds), undiagnosed skin lesions, poor circulation, all can be a relative contraindication to cryosurgery.

There is no need to fast and you can still eat and drink prior to the procedure.

Cryosurgery does not normally require a local anaesthetic. During cryosurgery, patients may feel a light tickle and sting as the lesion is frozen and then thawed.

Each lesion takes no more than a few minutes to treat depending on its size and thickness.

The frozen skin becomes white during treatment and takes a further few minutes to thaw back to room temperature.

The discomfort initially felt, would also last not more than a few mins. The process may be repeated if necessary once the skin has thawed.

Immediately after treatment, welling and redness may occur. This is the normal response to freezing the skin. This usually settles after 2-3 days.
