About Hydrozid®

Hydrozid® combines traditional cryotherapy and modern aerosol technology. Hydrozid® provides instant, safe, and effective treatment of lentigo and a wide range of additional skin lesions. Hydrozid® comes with a patented delivery system, contained in the spray head. The spray head was developed to ensure that a consistent, controlled spray is delivered every time. Hydrozid® contains the gas norflurane (R134a), which has been used in asthma inhalers for many years and is proven to be safe. Hydrozid® was developed by a family-owned pharmaceutical and medical device company in Denmark. It has been used successfully throughout Europe since 2013.

 

When applied to the skin surface, Hydrozid® generates temperatures between -58°F (-50°C) and -65.2°F (-54°C). This is well below the temperatures that result in cell death. The formation of intra- and extracellular ice crystals destroys the top layer of skin – without damaging the healthy tissue. Effective treatment is achieved through repeated freeze-thaw cycles. The procedure is very brief, effective, and patient friendly.

Instructions for use


Important: Hydrozid® should only be used by healthcare professionals

step-one
Step 1

Hydrozid® is applied to a lesion directly from the canister. Hydrozid® does not require any preparation time; no foam tipped applicators, tubes, replacing spent cartridges.

step-two
Step 2

Move the lock extension to the right to open the spray head. Hydrozid® is applied to a lesion directly from the canister. No anesthesia prior to treatment is required.

step-three
Step 3

Hydrozid® is now ready to use. To avoid damaging the surrounding tissue use one of the application templates provided in the Hydrozid® pack. Select the hole matching the size of the individual lesion. Freeze the lesion by applying Hydrozid® from a distance of 2 to 3 cm followed by a complete thaw.

After a short interval, repeat the freeze-thaw cycle. Several repeated freeze-thaw cycles are recommended as in a single treatment. The total duration of application to a lesion must be kept within the recommended maximum total. For large lesions, it is recommended to apply the jet in circular movements from the centre of the lesion toward the edge.

Treatment Times

The treatment time varies from one patient to another and depends partly on the location, thickness and appearance of the lesion as well as the patient’s skin type, age and other individual considerations. We always recommend making your own assessment on how to treat the specific plantar wart and only regard the treatment times as general guidelines.
