Introduction
Warts treated with liquid nitrogen cryotherapy will typically fall off within 1 to 3 weeks. This method uses low temperatures to cause local tissue necrosis and promote the shedding of warts. When warts are located on areas such as the back of the hand or face, and the individual has a strong constitution and good healing capacity, the warts usually fall off within 1 to 2 weeks. However, when warts are on the feet or soles and the individual has a weaker constitution and poorer healing ability, it generally takes 2 to 3 weeks for them to gradually fall off.
Liquid nitrogen cryotherapy for warts generally leads to shedding within 1–3 weeks, depending on individual constitution and the specific condition of the lesion. Details are as follows:
1. 1–2 weeks
Liquid nitrogen cryotherapy uses low temperature to induce local tissue necrosis and promote wart detachment. After treatment, the affected area may become red, swollen, and feel hot or burning; in severe cases, blisters may form. When warts are located on areas such as the back of the hand or face, and the individual has a strong constitution and good tissue repair capacity, the wart typically sheds within 1–2 weeks.
2. 2–3 weeks
If the wart is located on the foot or sole and the individual has a weaker constitution and poorer healing ability, it usually takes 2–3 weeks for the wart to gradually fall off.
If a single treatment does not completely remove the wart, multiple sessions of liquid nitrogen cryotherapy under a doctor's guidance, or alternative treatments, may be necessary.
