Cryotag skin tag remover works using cryotherapy which is the same trusted technology as used by doctors and dermatologists. The term cryotherapy comes from the Greek cryo meaning cold and therapy meaning to cure. World leading manufacturer in skin tag removal Developed by a world leading manufacturer with 20 years experience in cryotherapy and skin tag removal, Cryotag is clinically proven^** and instantly freezes the core of the skin tag, which destroys the tissue and causes the skin tag to fall off, in as little as 1 treatment^*. When the applicator is applied to the skin tag, the skin tag base will turn white within seconds as a sign that it is being frozen. The treatment will feel very cold which is normal. Most skin tags will fall off within 2 weeks, leaving you with a healthy looking skin.
