CryoPen Product - Dr Hass Clinic

What Is CryoPen and How Does It Work?

CryoPen is a precise, non-invasive treatment using controlled liquid nitrous oxide to freeze and remove unwanted skin lesions. The treated area naturally scabs and falls off, revealing smooth, clear skin underneath.

It is FDA-cleared and CE-marked, making it a clinically proven, safe option for all skin types and areas, including delicate zones such as the face, neck, and hands.

Commonly treated lesions include:

  • Warts – Raised viral growths, often on hands or knees
  • Verrucas – Hard, flattened warts on the feet caused by HPV
  • Skin Tags – Soft, hanging bits of skin on the neck, underarms, or eyelids
  • Milia – Small white cysts, commonly on the face
  • Sun Spots / Age Spots – Flat pigmented patches caused by sun exposure

CryoPen provides a safe, quick, and precise solution for lesions that are bothersome, unsightly, or causing discomfort.

How Does CryoPen Differ from Standard Cryotherapy?

Traditional cryotherapy sprays liquid nitrogen across a wide area, freezing healthy skin along with the lesion. CryoPen uses controlled liquid nitrous oxide delivered through a fine, pen-like applicator, allowing the freeze to be confined to the lesion itself.

This precision matters for three reasons:

  • Depth control: the temperature and duration are set to match the lesion, not estimated by spray distance.
  • Minimal impact on surrounding skin, reducing the risk of scarring or pigment change.
  • Suitability for delicate areas such as the face, neck, and eyelids, where a wider freeze zone would be unsuitable.

Dr Hasaneen Al Janabi selects the freeze depth and duration for each lesion individually at treatment, rather than applying a standard setting across all cases.

FAQs

Who can benefit from CryoPen?

CryoPen is ideal for anyone with warts, verrucas, skin tags, milia, or sun/age spots, especially in visible areas. It’s perfect for clients seeking a quick, minimally invasive solution, or those who have tried creams or home remedies without success.

What results can I expect?

Lesions usually scab and fall off naturally within 1–2 weeks, leaving smooth, clear skin. Stubborn or thicker lesions may require additional sessions. Results are clean and precise compared to older removal methods.

Is CryoPen safe?

Yes. CryoPen is FDA-cleared and CE-marked, and widely used by professional clinics across the UK. Mild redness, swelling, or scabbing may occur, but serious side effects are extremely rare when performed by trained practitioners. It is safe for delicate areas including the face, neck, and hands.

Does CryoPen hurt and is there downtime?

Patients may feel a brief stinging or freezing sensation during treatment. Downtime is minimal — normal activities can be resumed immediately, although mild redness or swelling may occur.

How many sessions will I need?

Most lesions are removed in a single session, but stubborn or thick lesions may require additional treatments.

How much does CryoPen cost?

Prices start from £79 per lesion for skin tags, warts, milia, or sun/age spots. For personalised pricing or package deals, contact our clinic.

Do I need a patch test?

Not usually. CryoPen is highly targeted and minimally invasive, so a patch test is rarely required.

I had a excellent experience with my XERF treatment. From start to finish, everything was explained clearly. I felt comfortable and well looked after. Dr Hass was accommodating, professional and reassuring throughout. The treatment itself was a positive experience and you instant tightening is visible. I'm delighted with the care and attention I received. I would highly recommend Dr Hass and the clinic to anyone considering XERF treatment. Thank you.

From start to finish I felt really well looked after. The clinic is clean and has a calm, soothing atmosphere, and Dr Hass took the time to answer every question I had, so I felt completely at ease all the way to the end. The XERF treatment itself was surprisingly relaxing, with no pain at all!! I’m already starting to look and feel refreshed, and I know the full results build up over time, so I’m excited to see the final effect. I’d recommend this clinic to anyone for its professionalism and genuine attention to patient care!!!

I went to Dr Hass over a week ago for cheek and chin filler and I love the results! Dr Hass took the time to listen to my concerns during the consultation and ensured the results were natural, as I wanted them. I was a bit nervous going into it but he was very professional, personable and kind and made me feel comfortable during the appointment- would highly recommend!

I had my Endolift treatment with Dr Hass and couldn’t be happier with my experience. From the initial consultation through to the treatment itself, I felt reassured and well looked after. Dr Hass was professional, knowledgeable and took the time to explain everything clearly, which made me feel at ease throughout. I wanted a subtle, natural-looking result rather than anything drastic, and I felt confident that Dr Hass understood exactly what I was hoping to achieve. The whole experience was positive, and I’m really pleased with the care and attention I received. I would highly recommend Dr Hass to anyone considering Endolift and looking for a professional, reassuring experience.

I recently went to Dr. Hass at Dr. Hass Clinic for an Endolift treatment, and I honestly couldn't be happier with the results! I had quite a bit of sagging skin, especially around my neck and lower face. The moment the procedure was done, I could immediately feel the tightening effect. The results were amazing right away the sagging on my neck completely disappeared, and my facial contours were lifted instantly. Dr. Hass is wonderful, so kind, and extremely professional. He explained everything in detail and took his time to focus precisely on the sagging areas where I needed it the most. I am so satisfied with my experience, I will definitely come back in the future, and I highly recommend him to anyone struggling with similar issues. He is truly one of the best, and I am so glad I found him and chose him!

I had my nose filler done by Dr. Hass, and I couldn’t be happier with the results! His knowledge, expertise and attention to detail were evident straight after the treatment. He understood exactly what I wanted to achieve and delivered the results I was hoping for. He also took the time to guide me through the process and advise me on the best approach to suit my nose and desired outcome. I’m extremely happy and satisfied with my results and would highly recommend Dr. Hass to anyone considering aesthetic treatments.

I am a lady in my early 50s I was very confused to choose a clinic that can remove my double chin which was really annoying me and making me lose my confidence. I finally found Dr. Hass clinic.

I personally didn’t feel any pain and when I saw the result I was amazed with the beautiful change … No more double chin 🥹🥹 It’s very important for all women to invest in their health and beauty.. I strongly recommend Dr Hass clinic and I would love to make another visit for different treatments 😊 Dr Hass you really changed my life by increasing my self confidence thank you so so much for everything 🥹🙏🏼🌹
