Wartie Cool uses its unique precision tip to accurately freeze the wart or verruca to its core. This rounded cryo tip allows for a precise application that is limited to the wart or verruca, thereby protecting the surrounding healthy skin. This leads to a more comfortable application experience. Following cryotherapy treatment, the treated area may turn white momentarily and later turn red as it thaws. The freezing process may cause a blister to form underneath the treated wart or verruca. Over the following 10 to 14 days, the wart or verruca should gradually fall off, revealing the healthy skin beneath. Most cases require only a single application for successful removal. However, should a second treatment be necessary, it's recommended to wait 14 days between applications. Ensure the metal tip returns to room temperature after each use (about 5 minutes) before using it again. In some instances, pre-soaking the wart in warm water can enhance the treatment's effectiveness, particularly for warts with a callused top layer.
