Wartner Cryotherapy is based on the liquid nitrogen method of cryotherapy, which is used by doctors. Clinical studies have proved that Wartner Cryotherapy is as effective as liquid nitrogen.
A clinical study to compare efficacy, tolerance and safety of 2 types of cryotherapy (liquid nitrogen (LN) and dimethylether/propane (DMEP) was performed by family physicians for warts on 124 patients (174 warts). Design of the study: randomized, multi-centered, controlled clinical trial with single blind assessment. Conclusions: The results show that both cryogenic agents were >90% effective. Liquid Nitrogen has a temperature of -196ºC, whilst DMEP is -57ºC and therefore much less likely to cause deep tissue damage.
Dermatologists confirm Wartner Cryotherapy’s effectiveness: “the efficacy of Wartner Cryotherapy freezing fluid is as effective as commonly used liquid nitrogen (= doctor’s method). In case of thick callosity we remove the callosity by scraping in a gentle way and apply Wartner Cryotherapy freezing liquid effectively” Dr I H Boersma – Dermatologist – Albert Schweizer Hospital – Zwijndrecht, The Netherlands.
“The effectiveness of Wartner Cryotherapy is comparable to that of the classic technique (Liquid Nitrogen = doctor’s method) in every respect, and the freezing effect it has is similar to that obtained by Liquid Nitrogen, perhaps a little slower (20″ application instead of 3″ application), which I think is safer and less painful” Dr J M Gray – Dermatologist – Paris, France
