Wartner is the world's #1 wart freezing brand! Warts are frozen to the core with a single treatment and results are visible within 10 days. Wartner Plantar Wart Remover is suitable for the removal of warts that appear on the soles of the feet, toes and heels which tend to be flat in appearance, sometimes covered by callous skin. Wartner Plantar Wart Remover is a cryotherapy option as used by doctors created to support treatment of warts at home and is proven to be as effective and safe as liquid nitrogen in the treatment of warts and verrucas. Wartner uses a mixture of dimethyl ether (DME) and propane, both of which are commonly used as propellants in products such as hair spray. This mixture freezes warts at a temperature of -57C. Wartner works by freezing the core of the wart, which is caused by the contagious human papilloma virus (HPV). Freezing the wart causes it to fall off in 10 to 14 days, by which time healthy skin will have formed underneath.
