Skin tags, medically known as acrochordons, are common, small, benign growths that often appear in areas where skin rubs against skin or clothing, such as the neck, armpits, or groin. Though harmless, many people seek removal for cosmetic reasons or to alleviate irritation caused by friction. Over-the-counter skin tag removal patches have become a popular, non-invasive method for addressing these growths at home.
The Mechanism of Patch Removal
Skin tag removal patches generally utilize one of two primary biological mechanisms: desiccation or occlusion. Desiccation involves applying a chemical agent, often salicylic acid, which is a keratolytic compound that encourages the skin tag cells to dry out and shed. The patch acts as a delivery system, holding the active ingredient directly against the growth and minimizing exposure to the surrounding healthy skin.
The other mechanism is occlusion, or strangulation, which physically restricts the skin tag. This approach involves a patch or a specialized band that applies constant pressure to the base of the growth, cutting off its blood supply. When blood flow is restricted, the cells undergo necrosis, or tissue death, leading to the growth’s eventual detachment. Patches that work through pressure or ligation are most effective on smaller skin tags with a distinct stalk.
Application and Expected Timeline
Proper application begins with cleaning the skin tag and the surrounding area thoroughly with mild soap and water. Ensure the area is completely dry before placement, as a dry surface is necessary for the adhesive to bond correctly and maintain the required seal. The patch should be centered directly over the skin tag, with the adhesive forming a complete barrier around the growth.
The patch is typically left in place for several hours or overnight, and then replaced according to the manufacturer’s directions, sometimes every 48 hours. Users can expect the skin tag to change color, often darkening, shrinking, and hardening as the process of desiccation or strangulation takes effect. The total timeline for detachment varies based on the tag’s size and the active mechanism, but removal can generally be expected within a few days to four weeks of consistent use.
Suitability and Safety Considerations
Skin tag removal patches are generally intended for use on small to medium-sized skin tags, typically those less than 5 millimeters in diameter. They are not appropriate for growths located in highly sensitive areas, such as near the eyes or on the genitals, or for tags that are already irritated, bleeding, or showing signs of infection. Individuals with sensitive skin should be cautious, as the concentrated active ingredients or the adhesive itself may cause mild, temporary redness or irritation on the surrounding skin.
Potential side effects can include localized dryness, peeling, or a mild burning sensation at the application site. If the area becomes painful, shows signs of a severe allergic reaction, or if the growth changes color in an unusual way, treatment should be discontinued immediately. It is best practice to consult with a healthcare professional before attempting at-home removal to confirm the growth is truly a benign skin tag and not another type of lesion that requires medical attention.
