What Are Skin Tags?

Skin tags, also known as acrochordons, are small, soft growths of skin that hang off the body by a thin stalk. These benign (non-cancerous) tumors typically appear in areas where skin rubs against skin or clothing, such as the neck, armpits, groin, eyelids, and under the breasts. Although they are common, especially in adults over the age of 50, skin tags are generally harmless. They can vary in size and color, often appearing flesh-colored, but may also be darker. While skin tags don’t pose a health risk, they can be bothersome, particularly if they get irritated or caught on clothing or jewelry.

Causes and Risk Factors

The exact cause of skin tags isn’t fully understood, but several factors may contribute to their formation:

• Friction: Skin rubbing against skin or clothing is a common cause.
• Genetics: A family history of skin tags can increase the likelihood of developing them.
• Hormonal changes: Pregnancy or conditions like obesity can make skin tags more common.
• Diabetes: People with diabetes tend to develop skin tags more often.

While they are typically not painful, they can become irritated, especially when in areas that experience frequent movement.

Dermatology Treatment Options for Skin Tags

If skin tags become bothersome or you simply want them removed for cosmetic reasons, dermatology offers several effective treatment options. A dermatologist can assess the skin tag and recommend the most appropriate method for removal:

1. Cryotherapy (Freezing): This technique involves applying liquid nitrogen to the skin tag, which freezes it off. Cryotherapy is quick and effective, although it might cause a slight stinging or burning sensation during the procedure.
2. Excision: A dermatologist may choose to cut the skin tag off with a sterile surgical scalpel or scissors. Local anesthesia is usually applied to numb the area, ensuring that the procedure is relatively pain-free.
3. Cauterization (Electrosurgery): In this method, a small electric current is used to burn off the skin tag. It is quick and effective, though it may leave a slight scab that falls off as the wound heals.
4. Ligation: This involves tying a small, sterile band around the base of the skin tag to cut off its blood supply. The skin tag eventually falls off after a few days.
5. Laser Treatment: A laser can be used to remove skin tags, especially if they are in more sensitive areas like the face or eyelids. This method is less invasive and has minimal downtime.

When to See a Dermatologist

While skin tags are typically harmless, it’s important to have any growth on your skin evaluated by a dermatologist if it:

• Changes in size, color, or shape
• Bleeds or becomes painful
• Appears in an unusual location or in clusters

A dermatologist can provide a proper diagnosis and ensure that the growth is indeed a skin tag and not another type of skin condition that requires different treatment.
