Cryopen is the leading cryosurgical treatment that is the most safest and highly effective method of freezing and removing benign skin lesions such as solar lentigines (sunspots, liverspots etc), seborrheic keratosis, and warts/verrucas. It uses highly pressured liquid nitrous oxide to destroy the tissue quickly and with little residual stinging. At Skin Architect, we carry this treatment using CryoPen. This advanced procedure does not require an anesthetic and is a convenient choice for clients due to minimal aftercare.

What is Cryosurgery / Cryotherapy?

The process of cryosurgery is the destruction of cells by using extreme coldness produced by nitrous oxide. Cryo necrosis starts in the tissue when the temperature in the cells reaches minus 127 degrees. As soon as this temperature is reached under high pressure and with millimeter precision, it bursts the membrane and restarts the natural dying process of the affected area.

Benefits of CryoPen Technology

Thanks to the advanced technology used during this treatment, there are many advantages. This includes the following:


Pinpoint accuracy (treats just the lesion and not healthy surrounding tissue)


Safe and proven treatment


Treats lesions from 1mm to 10mm in size


Safe for use on face and close to eyes


Minimal discomfort

Initial Consultation

At your initial CryoPen consultation, one of our skincare experts will examine any areas you wish to treat. From this, we can put together a plan and decide whether this is the most efficient course of treatment.

Depending on the size of the area you wish to treat, we may recommend CryoPen cryotherapy once, followed by an extra visit 4-6 weeks after to confirm that all pathological tissue has disappeared. In some cases, further treatment may be needed.

During Treatment

During treatment, highly pressurised liquid nitrous oxide is used to destroy skin tissue. It works by causing cryogenic cell death: killing the unwanted cells with extremely cold temperatures. CryoPen treatment is relatively pain-free, with most of our patients experiencing a mild stinging sensation for only seconds.

During Treatment

Due to the nature of CryoPen treatment, less aftercare is needed than with other methods such as electrocautery, cold knife or laser. The affected area is often known to heal quickly, with minimal issues. For 48-72 hours after treatment, it is important that you do not sunbathe or use other heat treatments such as sunbeds, sauna or steam. This also includes avoiding swimming, hot showers and baths. Please make sure to avoid applying makeup, soap, perfumed products or heavy moisturisers to the treatment area. Do not touch or cleanse the area or pick at any scabs that may form.

After CryoPen treatment, it is common to experience redness, swelling or blistering. This may last anywhere from a few hours to 48 hours after. You may apply aloe vera as required to the treatment area for the next 72 hours. When keeping this in the fridge, it has a nice cooling effect.

Regardless of the weather after your appointment, please make sure to use SPF 30 on the treated area. After the session, this area may appear darker, with scabs or crusting remaining for 10-30 days after. Total skin healing may take up to 3 months.

We recommend scheduling a follow-up appointment around four weeks after your treatment session to confirm that all pathological tissue has disappeared and whether additional treatment will be necessary.
