What is it?
The CryoIQ DERM Plus Liquid is a handheld cryosurgery device designed to treat benign skin lesions using liquid nitrous oxide (N₂O) spray freezing technology. Some key specs:
Freezing temperature: about –89 °C / –128 °F.
Uses a gas cartridge (16 g or 25 g N₂O) inserted into the device.
Ergonomic “pencil-type” grip for precise application.
Built-in non-return valve to prevent gas leakage and maximize usage.
How does it work?
The user positions the applicator tip very close (within ~1-4 mm) to the skin lesion and activates the lever, releasing liquid N₂O which rapidly evaporates, drawing heat away and freezing the tissue.
The freezing causes cell damage via ice crystal formation and membrane rupture — standard cryosurgery mechanism.
The user guide reports approx. 3 seconds of freeze equals ~1 mm depth penetration, though actual times vary by lesion size & location.
What is it used for?
The device is indicated for a variety of benign (and some premalignant) skin lesions, especially in settings like dermatology, general practice, podiatry, aesthetics, gynecology/urology and even veterinary use. Typical applications include:
Warts (including plantar warts)
Skin tags, seborrheic keratoses
Actinic keratosis (surface precancerous lesions)
Lentigo, age/sunspots, dermatofibromas, condylomas, molluscum etc.
Advantages & Considerations
Advantages:
High freezing temperature (–89 °C) means effective treatment of superficial lesions.
Ergonomic portable design suited for clinics or multi-site practice.
Cartridge usage may allow cost-effective treatments compared to more complex cryotherapy setups.
Important considerations / limitations:
It is for use by trained medical professionals. The user guide emphasises this.
Freezing too long or incorrectly can cause unwanted damage: pigment changes (especially on darker skin), nerve damage if close to nerve bundles, tissue damage behind ear/ fingers etc.
Contraindications include suspected skin cancer (needs biopsy), conditions like cryoglobulinemia, severe vascular disease, immunosuppression, certain anticoagulants, children under a certain age.
Precise freezing time depends on lesion type, size, location, depth and hydration of tissue. User guide gives suggested times for various lesions.
