From the Research
Cryosurgery for skin tags typically requires only a single treatment session for each skin tag, though larger or more stubborn skin tags might need 2-3 treatments spaced about 2-3 weeks apart. During the procedure, liquid nitrogen is applied to the skin tag for about 10-30 seconds, causing the tissue to freeze and eventually fall off within 1-2 weeks 1. The procedure is quick, usually taking just a few minutes per skin tag, and can be performed in a dermatologist's office without special preparation. After treatment, the area may be red, swollen, and form a blister that resolves on its own. Cryosurgery works by causing ice crystal formation within cells, disrupting cellular membranes and leading to cell death. This method is effective because skin tags have a narrow base that allows the entire growth to be frozen easily, cutting off its blood supply and causing it to detach naturally from the skin.
Some key points to consider when performing cryosurgery for skin tags include:
- The use of liquid nitrogen as the cryogen of choice 1
- The importance of allowing for a 5-minute freeze-thaw cycle to ensure optimum cellular degradation 1
- The potential for side effects such as bleeding, blistering, and hypopigmentation, although these are relatively rare 2
- The convenience and effectiveness of cryosurgery as a treatment option for skin tags, with high cure rates and good cosmetic results 2
It's worth noting that while cryosurgery is a highly effective treatment for skin tags, it may not be suitable for all patients, particularly those with darker skin tones or certain medical conditions 3. However, for most patients, cryosurgery is a safe and effective treatment option that can be performed quickly and easily in a dermatologist's office.
