Cryotherapy CryoPen skin removal

CryoPen uses extreme cold, down to −89°C, to freeze benign skin blemishes for removal. A nitrous oxide canister allows this temperature to be delivered with great accuracy.

CryoPen, created by H&O Equipment in Belgium, and the CryoMega II pen, created by CryoConcepts, are leading canister pens offering the highest level of performance and results. Both are FDA approved: cutting-edge equipment for the non-invasive treatment of skin tags, warts, milia, hyperpigmentation, cherry angiomas and seborrhoeic keratoses.

Once skin cells fall below −27°C they develop ice crystals within the cell. This process is called cryonecrosis: the cell membrane ruptures and the blood supply to the localised tissue being treated, such as a skin tag, is disrupted. Blistering is initially caused and within 1–3 weeks the skin flakes off, with rejuvenated skin underneath.

• Minimally invasive.
• No anaesthesia required.
• Able to resume normal activities straight after treatment.
• Virtually pain free — you are likely to feel a stinging sensation from the freeze.

• Increased precision, lowering the risk of damage to healthy tissue.
• Nitrous oxide instead of liquid nitrogen reduces the risk of burns and the handling of hazardous gases.
• Versatile for different skin blemishes and sizes from 1mm to 10mm; most removals are between 1mm and 5mm.
• Multiple blemishes can be treated in one session, making treatment efficient for the client.

This treatment is not suitable for anyone who is:

• Pregnant or breastfeeding.
• A patient with cancer, including melanoma and recurrent basal cell carcinomas.
• Living with Raynaud's syndrome.

Lesions in high-risk areas are also excluded: the nasolabial fold, preauricular area, immediate periorbital region, or areas where hair loss or pigment changes are critical.

Common

• Erythema (redness) and oedema (swelling) at the site — minor, temporary and usual for 2–3 days.
• Blistering to the area is expected due to skin shedding after treatment, lasting 10–14 days.
• A stinging sensation during treatment, not present for long afterwards.
• Headache if treating the head and scalp, usually lasting up to 2 hours.

Rare

• Hypopigmentation or hyperpigmentation — skin lighter or darker than the surrounding tone, usually lasting a few months.
• Treating areas with coarse hair can result in follicle damage and hair loss to that patch.
• Infection or delayed healing.
• Nerve damage risk when treating fingers, behind the ears and wrists.

All CryoPen removals require a follow-up appointment two weeks after treatment. This allows us to review effectiveness, answer your questions, take post-treatment photographs and discuss whether a further appointment is needed — which can happen with larger skin tags and warts because of their depth under the skin.
