What Are Skin Tags?

Skin tags, also known as fibroepithelial polyps or acrochordons, are non-cancerous and painless growths on the skin. Both men and women can get them. Almost 50-60% of adults develop skin tags in their lifetime. The chances of a skin tag forming increase after the age of 40 (1).

Skin tags can grow anywhere on the body. However, they are commonly found in the folds of the skin, like the neck, armpit, groin, and under the breasts.

They often occur in the areas of friction. They grow up to 5 mm in size. In rare cases, they can grow up to 1-2 cm.

A skin tag hangs off the skin by a small stalk. It is round and soft, and it is usually the color of your skin or hyperpigmented. The surface of the skin tag may be smooth and irregular in appearance. Most skin tags or soft fibromas are painless and cause no adverse effects. In some cases, they may get sore and bleed due to rubbing against clothing or jewelry.

Small skin tags are up to 1 to 2 mm in width and height. Mid-sized are 5 mm long and 2 mm wide. Large skin tags may appear bag-like. You may also experience dry skin in the surrounding area.

Skin tags can form due to various reasons like obesity, diabetes, genetics, etc. Read on to know what causes the development of skin tags.

Individuals with genetic disorders such as Birt-Hogg-Dube (BHD) syndrome or tuberous sclerosis may be predisposed to skin tags. In these cases, skin tags often appear in multiple numbers around the neck (in a necklace-like pattern) and are referred to as “molluscum pendulum necklace sign” (1).

Since a skin tag is associated with these issues, you may need to visit a doctor for a brief evaluation. Keep reading to know more about skin tag diagnosis.

Your doctor may ask about your medical history and conduct a physical examination to check if it is a skin tag or some other type of skin growth. For obese patients, the doctor may record their BMI (Body Mass Index). The doctor may also check total cholesterol and LDL (low-density lipoprotein) serum levels before suggesting treatment (4).

There are both medical and over-the-counter dermatological treatments available for skin tag removal. Keep reading to learn how to get rid of skin tags.

How To Treat Skin Tags

To remove a skin tag medically, visit a doctor. The doctor may use the following methods:

  • Cryotherapy, which involves freezing the skin tag with liquid nitrogen.
  • Surgical removal with scissors or scalpel.
  • Burning off the skin tag with high-frequency electrical energy.
  • Ligation, which involves tying it off with surgical thread to cut off its blood flow.

Some patients may require topical application of an anesthetic to ease the pain. The tiny wound caused by the excision will heal on its own.

Removing skin tags at home is not recommended as it poses the risk of infection and injury. But if you are convinced you want to try to remove these skin growths at home, listed below are some home remedies you can try out.

Home Remedies To Remove Skin Tags

How To Prevent Skin Tags

Since the cause of skin tags is not clear, there are no specific prevention tips that you can follow to prevent this cosmetic concern. However, you may consider following a healthy lifestyle to prevent them. Dr. Michael Newman, a board-certified plastic surgeon, says, “Because skin tags are more common in overweight or obese persons, decreasing weight may help prevent new growths. Avoid wearing clothes and jewelry that are too tight or rub against your skin to help reduce friction.”

Worried about the skin tags you have begun to notice on your body. Read on to find out when you should consult a doctor.

When Should You See A Doctor?

According to Dr. Newman, “You may visit a doctor if the color of the skin tag changes or you experience any discomfort.”

Skin tags may cause irritation due to skin, dress, or jewelry rubbing against them repeatedly. Consult your doctor to understand the best skin tag removal options. It is safe to remove them through medical procedures. Dr. Emily Wood, a board-certified dermatologist, says, “Home remedies often involve snipping the lesions with small scissors. It can be anxiety-provoking for patients to treat their own skin tags, so I recommend seeing a board-certified dermatologist to decide which treatment method is most appropriate for your skin type.”

A skin tag is a benign lesion. But, sometimes, other skin conditions like warts and moles resemble skin tags, and some of them may be skin cancers. So, it is best to have it examined by a doctor who specializes in dermatology to avoid complications from these skin lesions.

Frequently Asked Questions

Do skin tags grow back?

No, skin tags do not grow back after removal. However, multiple skin tags may develop in the same region of the body.

Does eating too much sugar cause skin tags?

Skin tags have been associated with high blood sugar levels in the body (5). Eating too much sugar can contribute to spikes in blood sugar levels in individuals with insulin resistance and may lead to skin tags. However, more research is needed to understand the mechanisms by which insulin resistance and skin tag formation are connected.

Can baking soda remove skin tags?

Anecdotal evidence suggests that baking soda applied as a paste on skin tags may help remove them. However, there is no scientific evidence regarding the safety and efficacy of this skin tag removal method.

Do skin tags spread?

No, skin tags do not spread from one individual to another or from one part of the body to another. However, friction in skin folds and other factors may lead to multiple skin tags on different parts of the body in individuals prone to developing skin tags.
