Warts are the result of a HPV infection, a common virus, affecting almost every person at least once during their lifetime. Some strains cause warts on the hands, others on the feet or face and so on. Warts can look very different depending on where on the body they are located and the type of strain of the HPV virus.

Just like liquid nitrogen wart removal, the Cryopen uses very low temperatures to target the wart. The Cryopen is an advanced cryotherapy innovation and uses a fine jet of N 2O at a temperature of –89°C, to thoroughly freeze the wart.
