Story at-a-glance -

  • Skin tags (acrochordons) are small, noncancerous (benign) growths that usually measure only a few millimeters in length, though they can grow up to half an inch
  • Experts don’t know the exact cause of skin tags, but they believe that these growths appear when skin rubs against skin

Your skin is the heaviest organ in the body and takes up about 16 percent of your total weight.1 It serves many purposes, such as protecting your internal organs from microbes and environmental heat, as well as regulating body temperature.2 But due to its size and breadth, there’s a chance that growths can unexpectedly form. One common example found among adults is skin tags.

What Are Skin Tags?

Skin tags (acrochordons) are small, noncancerous (benign) growths that usually measure only a few millimeters in length, though they can grow up to half an inch.3 They typically appear on the neck, armpit, groin or inframammary areas.4 Almost half the population has been reported to have a skin tag, but the condition is more associated with obese people.5 Skin tags are also rare during childhood, but older people have an increased chance of developing them.6

While harmless, skin tags can affect your quality of life.7 For example, if a skin tag grows on your eyelid, you may want to have it removed for cosmetic reasons. A skin tag may also cause friction in your clothing, which can lead to skin irritation and bleeding.8

What Causes Skin Tags?

Experts don’t know the exact cause of skin tags, but they believe that these growths appear when skin rubs against skin. As such, skin tags are often found in armpits, or on the neck and groin.9 In other cases, your skin tag may be confused with a condition known as the Birt-Hogg-Dube (BHD) syndrome, a condition that produces growths on the skin that look exactly like  skin tags.10

The cause of BHD syndrome is a mutation in your FLCN gene that produces folliculin, which is a tumor-suppressing protein. Eventually, the mutation causes “multiple fibrofolliculomas and trichodiscomas that may be indistinguishable from skin tags.”11

To be clear, topical growths caused by BHD syndrome are not skin tags — they only look very similar. The cause of regular skin tags is still unknown. Other risk factors can influence the appearance of skin tags, namely:12

  • Gender — Women are more likely to develop skin tags compared to men.
  • Age — Skin tags are more commonly found in middle-aged and elderly citizens.
  • Weight — Overweight and obese people have a higher chance of developing skin tags.
  • Lifestyle — One study notes that skin tags may signify metabolic syndrome.13

If you discover any unusual growths on your skin, don’t immediately assume it’s a skin tag, as it could indicate a more severe condition. Visit a doctor before doing anything else.

How to Get Rid of Skin Tags

Oftentimes, skin tags aren’t actually removed. Since they don’t affect your health, there’s no need to remove them unless you really want to. The only exception to this rule is during childhood. If a skin tag grows on a child, it could indicate nevoid basal cell carcinoma, a rare genetic condition linked to skin cancer.14

If you do happen to have a skin tag that you want removed, but you’re not confident removing it on your own, you can visit a dermatologist who will employ one of three different methods:15

  • Manual — A scalpel will be used to remove the skin tag.
  • Cryosurgery — The skin tag will be frozen to help facilitate easy removal.
  • Electrosurgery — A device with an electric current will safely burn away the skin tag.

If circumstances don’t permit you visiting a doctor, it’s possible to remove skin tags on your own. Here are three ways you can try to help remove skin tags manually at home:

String

Follow this simple procedure that you can do at home:16

1. Get a thin string, such as a dental floss.

2. Tie off the base of the skin tag to cut off blood supply.

3. The skin tag will fall off after a while.

 

Onion juice and salt

To use onion juice and salt, follow these steps:17

1. Chop an onion and cover it with salt.

2. Leave the mixture overnight.

3. Squeeze out the juice and apply it to the skin tag three times a day until the skin tag disappears.

 

Iodine

If you have iodine at home, you can use it to remove skin tags:18

1. Spread coconut oil on the skin tag.

2. Pour iodine on a cotton bud and spread it across the skin tag.

3. Cover with a bandage until the iodine dries.

4. Repeat the procedure twice a day.

 

Essential Oils for Skin Tags: Tea Tree, Oregano and Helichrysum Oils

Essential oils contain anti-inflammatory and antimicrobial properties that may help remove skin tags naturally. One solution that’s becoming popular is the use of tea tree oil, which is a potent product derived from the Melaleuca alternifolia tree from Australia.19 This plant has been studied extensively, with research pointing out that it can help fight bacteria,20 fungi21 and viruses.22 Furthermore, other experts note that tea tree oil contains anti-inflammatory properties.23,24,25

To use tea tree oil for skin tags, follow these steps:

  • Pour a few drops of the diluted essential oil on a cotton ball.
  • Place the cotton ball on the skin tag and secure with a medical bandage.
  • Leave it on your skin for 10 minutes, repeating the procedure three times a day until the growth falls off.

It’s important to note that you should never use tea tree oil on skin tags around your eyes.26 Two other essential oils that may be effective against skin tags include:

Oregano oil:27

1. Thoroughly mix three drops of oregano oil in one-half teaspoon of carrier oil.

2. Pour a few drops of the mixture on a bandage or gauze.

3. Leave it on the skin tag for several hours or overnight.

 

Helichrysum oil:28

1. Mix four drops of helichrysum oil, three drops of oregano oil and 1 ounce of carrier oil in a container.

2. Rub the mixture to the skin tag using your fingertips or a soft cloth.

 

Using Apple Cider Vinegar for Skin Tags

Another popular home remedy for removing skin tags is apple cider vinegar (ACV), a product made by fermenting the sugar in the fruit until it turns into acetic acid.29 The method of application is the same as for tea tree oil:

  • Put a few drops of ACV on a cotton ball and bandage it to the skin tag.
  • Repeat three times a day until it falls off.

Note: Do not use around the eyes as it can cause irritation. If other allergic reactions appear, stop using the vinegar and look for other natural alternatives.30

If You Do Choose to Remove Skin Tags, Remember to Prioritize Your Safety

If you notice a growth on your skin, don’t assume it’s a skin tag right away. Check with a doctor first, as it can signify a more severe condition. If the growth is confirmed to be a skin tag and you want to remove it manually, sterilize your tools and check for any allergic reactions first, particularly if applying essential oils. If home remedies don’t work, you may visit a dermatologist as a last resort.
