CryoPen - Lesion Freezing

The CryoPen lesion freezing procedure begins with a thorough consultation and examination by one of our qualified clinicians. We will assess your lesion to confirm it is suitable for cryotherapy treatment and discuss your medical history. Once confirmed as appropriate, the treatment itself takes just a few minutes. The CryoPen applicator is held millimetres from the skin and delivers a precise stream of nitrous oxide at minus 89 degrees Celsius directly to the lesion. You may experience a mild stinging or cold sensation during the application, but this typically subsides quickly and most patients find the procedure very tolerable.

Following treatment, the frozen lesion will typically form a small blister or crust within 24-48 hours. This is a normal part of the healing process. Over the following two to four weeks, the treated area will naturally shed, revealing new healthy skin beneath. We provide comprehensive aftercare instructions to ensure optimal healing. In some cases, particularly with larger or deeper lesions, a second treatment session may be recommended after 4-6 weeks to achieve complete removal.

CryoPen treatment integrates seamlessly with our other Dermatology services and can be combined with procedures such as Mole Checks for comprehensive skin health management. Our Portsmouth clinic is easily accessible for patients throughout Hampshire, offering flexible appointment times to fit around your schedule.

CryoPen cryotherapy is effective for treating a wide variety of benign skin lesions. Common conditions we treat include warts, verrucas, skin tags, cherry angiomas, age spots, sun spots, seborrheic keratosis, and milia. The treatment is also suitable for removing benign pigmented lesions and certain types of viral lesions. Each lesion type responds differently to cryotherapy, and our experienced clinicians will determine the most appropriate treatment approach for your specific condition.

It is important to note that CryoPen is only used for benign lesions. Any suspicious lesions or those with characteristics that may indicate skin cancer will not be treated with cryotherapy and will require alternative management, including possible biopsy or referral to a specialist. During your consultation, our clinician will carefully examine your lesion and may recommend alternative treatments if CryoPen is not appropriate. We prioritise patient safety and ensure every lesion is properly assessed before proceeding with any treatment.
