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.

Before & Afters

Subtle refinement achieved through precision, proportion, and restraint. At Dr Hass Clinic, no two results are ever the same.

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.

Would highly recommend the Dr Hass Clinic. From booking my initial consultation right through to aftercare, every interaction has been quick, easy and professional. After having Endolift on my face with exceptional results, I had no hesitation in booking an Endolift body treatment for my thighs. Due to the amount of loose skin, I had always assumed surgery was my only option. I didn’t want to trade sagging skin for scars, and I also didn’t have the budget or the time for surgery and a lengthy recovery. I was therefore over the moon when Dr Hass explained that I could achieve visible skin tightening results with Endolift. I’ve just had the treatment, so I’m now really excited to see the results develop! The level of care, expertise and attention throughout has been brilliant. I’m particularly self-conscious about my thighs, but Dr Hass made me feel completely at ease and comfortable throughout the consultation and treatment. The treatment itself was also practically pain-free. I genuinely wouldn’t hesitate to recommend Dr Hass and his clinic. He clearly knows his stuff, takes great care of his patients and, as an added bonus, is actually a really cool guy to spend a few hours, I’m now a country music fan too!

I am so lucky to have found Dr. Hass. I recently did an Endolift procedure on my body and couldn't be happier that I chose to go with this clinic. I first had a consultation where Dr. Hass went through the whole procedure in detail and made me feel heard. I then came in for the actual procedure, feeling quite anxious as I never had anything similar done. The procedure went through so smoothly, and the pain was very minimal. Dr. Hass ensured I felt comfortable, and was very patient with me the entire time. He is definitely at the top of his field, so I felt safe being in his hands. I'm still in the process of recovery but I have minimal bruising and swelling and everything is healing really well. I already told Dr. Hass that I will come to him for any future procedure or cosmetic enhancement!

I visited Dr. Hass for a non-surgical nose treatment and I couldn't be happier with the results. My nose was lifted instantly and the whole procedure was very quick and painless. I don't live in the UK, but I would absolutely travel back to London to have this treatment done again. I highly recommend Dr. Hass

I had a really nice consultation. He took the time to explain everything clearly and answered all of my questions, which made me feel really comfortable. I also liked that he recommended a treatment that actually suited my age, my skin, and my facial structure instead of just suggesting anything. I think that’s really important because everyone’s face is different. Overall, I had a great experience and would definitely recommend him.

Dr. Hass was absolutely amazing! I had an Endolift laser treatment with him, and I couldn't be happier with my experience. He was incredibly attentive, took the time to listen to all my questions, and always responded to my messages straight away, which made me feel really cared for throughout the whole process. He offers great prices, the clinic is beautiful, friendly and welcoming. The atmosphere is relaxed and professional, making every visit a pleasure. It's only been two weeks since my treatment, and I'm already so impressed with the results. My face looks more lifted, refreshed, and defined, and I've had people commenting on how good my skin looks. Knowing that the full results continue to develop over the next three months makes me even more excited to see the final outcome. I was so impressed that I brought my mum and sister with me, and they both loved their treatments too! I honestly can't recommend Dr. Hass enough. If you're thinking about having Endolift, I highly recommend him. Thank you for such an amazing experience—I can't wait to come back for more treatments!

I can’t recommend Dr Has enough. I visited his clinic on Harley Street for tear trough filler / skin tightening, and the whole experience was excellent from start to finish. The tear trough results were instant. I noticed the difference straight away and couldn’t be happier. Dr Has is genuinely friendly and incredibly professional. He took the time to explain everything, made me feel completely at ease, and made sure the entire process was smooth and comfortable. It’s clear he really knows his craft and cares about getting the best results for his patients. If you’re considering any aesthetic treatments, this is the place to go. Thank you Dr Has!

I saw Dr Hass for dermal filler, and I couldn’t be happier with my experience. As it was my first time having the treatment, I was quite nervous, but he immediately made me feel comfortable and at ease. He took the time to answer all of my questions thoroughly and explained everything clearly, which gave me a lot of confidence throughout the appointment. I’m so pleased with the results. I wanted a subtle, natural look, and he achieved exactly what I was hoping for. I would highly recommend Dr Hass to anyone considering aesthetic treatments, especially if it’s your first time. He’s skilled, reassuring, and genuinely cares about achieving the right result for you!
