Viral Warts: Treatment and Care Tips - Dermatology

More Info

Viral warts, also known as verrucae vulgaris, are benign epithelial tumors caused by the human papillomavirus (HPV). They can appear anywhere on the body, but common sites include the hands, feet, and face. The appearance of a wart can vary; they may be rough, raised, and can sometimes have a dark center due to thrombosed capillaries.
In your case, you mentioned that you have a wart on your left cheek that is hard and dark. You have already undergone one session of cryotherapy, which is a common treatment for warts. Cryotherapy involves freezing the wart with liquid nitrogen, causing the wart tissue to die and eventually fall off. The number of treatments required can vary significantly from person to person. Typically, it may take anywhere from one to several sessions, depending on the size, location, and depth of the wart. Some warts may respond well to just one treatment, while others may require multiple sessions spaced a few weeks apart.

Regarding the use of breathable tape, it is generally not recommended to cover a wart with tape unless advised by a healthcare professional. While some people use duct tape occlusion therapy as a home remedy, the evidence supporting its effectiveness is mixed. If you choose to cover the wart, ensure that the tape is breathable to avoid trapping moisture, which could lead to skin irritation or infection.

Salicylic acid is another common treatment for warts. It works by softening the skin and gradually peeling away the wart. Applying salicylic acid can be effective, especially for superficial warts. However, it may take several weeks of consistent application to see results. It is essential to follow the instructions carefully and avoid applying it to surrounding healthy skin to prevent irritation.

In summary, the treatment of viral warts can vary based on individual response and the specific characteristics of the wart. Cryotherapy may require multiple sessions, and while salicylic acid can be beneficial, patience is key as it may take time to see improvement. If you have concerns about the wart's appearance or treatment effectiveness, or if you experience any adverse reactions, it is advisable to consult with a dermatologist for further evaluation and tailored treatment options.
