Skin tags are common, benign skin growths often found where skin rubs, like the neck or armpits. While harmless, many choose removal for cosmetic reasons or if irritation occurs. Cryotherapy, or freezing, is a popular and effective method for skin tag removal. This article explains the healing process after a skin tag has been frozen.
Understanding the Freezing Process
Cryotherapy works by applying extremely cold temperatures, often using liquid nitrogen, directly to the skin tag. This intense cold freezes the cells, causing cell death. Immediately after treatment, the skin tag may turn white or gray. A blister, which can be clear or blood-filled, usually forms within 24 hours. This normal response indicates the frozen tissue is damaged and beginning to detach.
Typical Timeline for Resolution
Skin tags typically fall off within 1 to 3 weeks after freezing, though this can vary. Many fall off within 7 to 14 days. During the first few days, redness, slight swelling, and possible blistering are common. The skin tag then starts to dry out and darken, often forming a scab, around day 4 to 7. The treated skin tag, along with the scab, should naturally detach over the following week or two.
Several factors can influence this timeline, including the skin tag’s size and location. Larger or thicker skin tags may take longer to fall off, potentially up to a month, or may require multiple treatment sessions. Individual healing rates also play a role. If a skin tag has not fallen off after three weeks, or if it looks unchanged, a follow-up with a healthcare provider may be needed for re-treatment.
Aftercare and What to Expect Next
After the skin tag falls off, the treated area will reveal new, pink skin underneath. This pink appearance is not scarring and will gradually match the surrounding skin over several weeks. Keep the treated area clean and dry for proper healing. Gently wash with warm water and mild soap, then pat dry.
Avoid picking or scratching the treated area or any scab, as this can delay healing or lead to complications. If a blister forms, do not puncture it. Applying petroleum jelly or a similar emollient daily for about two weeks can help the area heal and prevent crusting. While rare, contact a healthcare professional if you notice signs of infection such as persistent bleeding, oozing, increased pain, spreading redness, or a foul smell. Seek medical advice if the treated area has not healed within six weeks.
