How long does it take for blisters to form after cryotherapy for plantar warts?
A blister refers to a vesicle. In most cases, it may take 1 to 3 days for a blister to form after cryotherapy treatment for plantar warts. The detailed analysis is as follows:

Cryotherapy is a common treatment method for plantar warts, which works by lowering the temperature of the wart tissue, causing cells to freeze and die, ultimately leading to the shedding of the wart. For smaller and more superficial warts, the tissue damage caused by cryotherapy is relatively mild, and the body quickly initiates the healing process; blisters usually appear within 1 to 2 days after treatment. These types of warts are generally less complicated and tend to form blisters easily, beginning the healing process promptly.
However, for larger or deeper warts, because of their greater size or depth, cryotherapy requires more time to completely destroy the infected tissue. As a result, tissue damage is more severe, and the initiation of the healing process is relatively delayed, so it may take about 3 days for a blister to appear. These types of warts may be more stubborn, and the treatment and recovery process may take longer.
After undergoing cryotherapy, follow-up care and management should be performed according to the doctor's instructions to promote healing and recovery. Additionally, it is important to maintain a light diet and avoid spicy or irritating foods such as chili peppers and pepper, which can help support skin recovery.
