CryoPen is a handheld, pen-shaped device that uses pressurised liquid nitrous oxide (N2O) to perform cryotherapy, a procedure that destroys unwanted benign skin lesions. The device delivers a fine, cold jet of N2O to the affected area, freezing the tissue and causing ice crystals to form and rupture cell membranes, thus destroying the cels. It is a precise and quick treatment for conditions like skin tags, warts, sunspots, and pigmentation, with minimal discomfort and no need for anesthesia.
Freezing Technology: CryoPen utilises a high-pressure, liquid nitrous oxide gas to create a temperature of approximately -89°C.
Cell Destruction: The extreme cold freezes the inter-cellular fluid within the target lesion, forming ice crystals that burst the cel membranes, leading to cell destruction.
Precision: The fine jet of nitrous oxide allows for millimeter-precise application, minimising damage to healthy surrounding tissue.
Quick Procedure: Treatments can take as litle a s a few seconds t o a few minutes per lesion.
Minimal Discomfort: The process is generally well-tolerated, with little to no residual stinging.
No Anesthesia Required: The procedure is performed without the need for topical numbing or anesthetic.
Minimal Downtime: Patients can often resume normal activities immediately after treatment.
Recovery Time: Healing may take several weeks, with results becoming observable within 1 to 6 weeks.
Potential Side Effects: While generally safe, some minor side effects can occur, including temporary redness, blistering, and swelling. In rare cases, there might be hypo-pigmentation, nerve damage leading to numbness (though nerves often regenerate), or infection of the blister.
Aftercare: A follow-up appointment is often recommended to assess the treatment’s response and determine if additional sessions are needed.
