From the Research
Acrochordons, commonly known as skin tags, are small, benign growths of skin that can be removed for cosmetic purposes or if they become irritated, and the most effective removal method is freezing with liquid nitrogen (cryotherapy) as it is a safe and efficient procedure 1.
Definition and Causes
An acrochordion is a small, benign growth of skin that typically appears as a soft, flesh-colored or slightly darker flap attached to the skin by a thin stalk. These harmless growths most commonly occur in areas where skin rubs against skin or clothing, such as the neck, armpits, eyelids, groin folds, and under breasts.
Risk Factors
Skin tags are more common in middle-aged and older adults, people who are overweight, and those with diabetes, as shown in a study that found a significant association between acrochordons and the components of metabolic syndrome 1.
Removal Options
While skin tags don't require treatment for medical reasons, they can be removed for cosmetic purposes or if they become irritated. Removal options include:
- Snipping with sterile scissors
- Freezing with liquid nitrogen (cryotherapy)
- Burning with electrocautery
- Tying off with a string to cut off blood supply These procedures should be performed by a healthcare provider to prevent infection or scarring. Never attempt to remove skin tags at home as this can lead to bleeding, infection, or improper removal.
Safety of Cryotherapy
The use of liquid nitrogen for cryotherapy is safe and effective, with minimal risk of contamination, as shown in studies that found low levels of microbial contamination in liquid nitrogen storage tanks 2, 3.
Importance of Professional Removal
It is essential to have skin tags removed by a healthcare provider to prevent complications and ensure proper removal. Attempting to remove skin tags at home can lead to bleeding, infection, or scarring, and may not be effective in completely removing the skin tag.
