Skin tags are common, harmless skin growths that many individuals choose to have removed, often for cosmetic reasons or if they become irritated by clothing or jewelry. Freezing, or cryotherapy, offers a non-invasive method for removing these small skin protrusions. Understanding the process and subsequent healing timeline can help manage expectations during recovery.
Understanding Skin Tag Freezing
Cryotherapy involves using extreme cold to destroy unwanted tissue. For skin tags, this typically means applying liquid nitrogen directly to the growth. The cold freezes and damages the cells within the skin tag, which cuts off its blood supply. The tag then dries up and eventually detaches. It is a common method for skin tag removal, often performed in a quick office visit.
Initial Changes After Freezing
Immediately following cryotherapy, the treated area may sting or itch, typically subsiding within minutes. Within the first 24 hours, redness, slight swelling, and a blister commonly appear. This blister, visible or not, is a normal healing response, indicating effective treatment. Sometimes, a blood blister may form, which is also harmless.
When the Skin Tag Falls Off
After initial reactions, the blister typically dries and darkens, often forming a scab within one to seven days. The treated skin tag will then shrivel and darken as it dries. Most frozen skin tags fall off naturally within 7 to 14 days after the procedure. While some detach in a few days, others, especially larger tags or those in high-friction areas, could take up to three weeks or a month. Allow the skin tag to fall off on its own; picking or pulling can delay healing, increase infection risk, or lead to scarring.
What Affects Healing Time
Several factors influence how quickly a frozen skin tag heals and detaches. The size of the skin tag plays a significant role; larger tags may require more extensive freezing and thus a longer healing period. Location also matters, as areas with more movement or friction, such as the underarms or neck, might experience slower healing. An individual’s healing capabilities and skin sensitivity can lead to variations in the timeline. The specific cryotherapy method and duration, including multiple freezing cycles, can also impact recovery time.
Caring for the Treated Area
Proper aftercare is important for optimal healing and to prevent complications. Keep the treated area clean and dry, gently washing it daily with mild soap and water. Applying petroleum jelly or an antibiotic ointment, if recommended, can help keep the area moisturized and protected. Avoid picking, scratching, or rubbing the treated site, and refrain from using harsh chemicals, exfoliants, or makeup until fully healed. If you observe signs of infection, such as increased pain, spreading redness, pus, or fever, or if the skin tag has not fallen off after three weeks, consult a healthcare provider.
