Treat one wart first to check how your skin tolerates the product before treating others. On day one, use the cryotherapy applicator on the wart as directed on the pack. From day two to day five, apply the acid gel to the wart — twice daily for adults, once daily for children. The skin will darken and begin to peel, forming a scab; peeling is a natural part of the process and continues for one to two weeks after the treatment period. A maximum of three complete treatment cycles may be carried out.

For external use only, on the hands and feet only. Do not use on children under four years of age, on any other part of the body, on bleeding, irritated or inflamed skin, on open wounds, on warts larger than 5mm, or on skin tags, moles, birthmarks or any lesion you suspect may be skin cancer. Consult your doctor before use if you are pregnant or breastfeeding, have diabetes, poor blood circulation or a skin condition, or are taking anticoagulants. Contains pressurised gas — keep away from heat and flame. Keep out of reach of children.
