Introducing Hydrozid cryogenic spray. Efficacy with modern-day convenience.

Actinic Keratosis

With increasing UV levels and the quest for sun all year round, as many as 23% of your patients over 60 may be presenting with actinic keratosis (AK), also known as solar keratosis which, as the name suggests, is the consequence of sun exposure over many years.

Lesions are very uncommon in patients under 45 years of age, but the incidence increases after this, particularly in men and especially in those with fair skin, blue eyes and blond skin.

This now-common, sun-induced scaly lesion can potentially transform into a squamous cell carcinoma (SCC). While this risk is very low, a patient with 10 AK has a 14% increase in risk of developing SCC over five years.

As such, it is imperative that these patients are identified and treated.

Once you have confirmed a diagnosis of AK, the PCDS recommend cryotherapy for cases where there are few lesions, or if the lesions are widely distributed, for example around the face, scalp, neck and hands.

The limitations of traditional cryotherapy systems

While cryotherapy may be a routine procedure, the issues arising from using liquid nitrogen- or CO2-based systems make it far from straightforward. For example, there are Health and Safety issues to be considered when storing and handling liquid nitrogen; CO2-based cryotherapy machines are cumbersome to operate and require meticulous servicing.

Introducing Hydrozid. Efficacy with modern-day convenience

Designed in Denmark, Hydrozid is a CE-marked cryotherapy that achieves the same level of efficacy as the traditional systems – but without any of the inconvenience of storing hazardous materials or using bulky equipment.

New Hydrozid comes in a user-friendly aerosol containing 250ml of the liquefied gas norflurane. The compact system makes it convenient to use in any size of clinic and the norflurane gas is 100% safe.

What’s more, each aerosol comes with its own handy plastic template with a range of six appertures. Simply select the correct aperture for the lesion and spray. The norflurane gas will quickly and effectively freeze the lesion, while the template will protect the surrounding healthy tissue from damage.

Where several repeated freeze-thaw cycles are recommended, the template ensures that only the treatment area is ever exposed, so minimising discomfort for the patient.
