Skin tags are small, soft pieces of skin. They hang from the body by a thin stalk. You may see them on your neck, armpits, or eyelids. They are harmless and usually painless. But why do they appear? What causes skin tags? In this article, we will explore the main reasons for skin tags and help you understand them better.
What Are Skin Tags?
Skin tags are small growths. They look like tiny flaps or bumps. Their color is usually the same as your skin or a bit darker. They can be smooth or wrinkled. Most skin tags are less than 5 millimeters in size, about the size of a grain of rice.
They can grow anywhere on the body. But they are common where skin rubs together. For example, under the arms, on the neck, or under the breasts. Skin tags are not dangerous. They do not turn into cancer. Many people have them, especially as they get older.

Main Causes of Skin Tags
Skin tags appear because of several reasons. Here are the main causes:
1. Skin Friction
One of the most common causes is skin rubbing against skin. When two areas of skin rub together often, a skin tag can form. For example, the neck and collar area, or under the arms. This rubbing causes the skin to grow extra tissue as a small tag.
2. Age
Skin tags are more common as people get older. They often appear after age 40. The skin changes with age. It may grow small tags more easily. Younger people can get them too, but it is less common.
3. Obesity
People who are overweight or obese often have more skin tags. Extra body weight means more skin folds. These folds rub together, causing tags. Losing weight may help reduce skin tags over time.
4. Genetics
Sometimes skin tags run in families. If your parents or grandparents had skin tags, you might get them too. Genes can make your skin more likely to grow these tags.
5. Hormonal Changes
Hormones can also play a role. For example, pregnant women may get skin tags more often. This is because of changes in hormone levels during pregnancy. Some people may get more skin tags during puberty or other hormone changes.
6. Diabetes And Insulin Resistance
People with diabetes or insulin resistance often have more skin tags. Insulin affects how your body grows skin cells. High insulin levels can cause extra skin growth. This is why skin tags sometimes appear before diabetes is diagnosed.
7. Human Papillomavirus (hpv)
Some studies suggest a link between skin tags and HPV. HPV is a virus that affects skin cells. It can cause growths like warts. But more research is needed to know if HPV causes skin tags for sure.
8. Pregnancy
Pregnancy causes many changes in the body. Skin tags may appear during pregnancy. This happens because of hormone changes and skin stretching. The tags often go away after pregnancy, but not always.

Where Do Skin Tags Usually Appear?
Skin tags like warm, moist places. They often grow in these areas:
- Neck
- Underarms
- Under the breasts
- Groin
- Eyelids
- Upper chest
These areas have skin rubbing together or skin folds. This explains why skin tags grow there.
How Do Skin Tags Form?
Skin tags form when skin grows extra tissue. This can happen when skin is irritated or rubbed. Small blood vessels and collagen grow under the skin. This creates the soft, hanging bump we call a skin tag. They often start very small and grow slowly over time.
Who Gets Skin Tags?
Skin tags can happen to anyone. But some groups have more skin tags:
| Group | Reason |
|---|---|
| Older Adults | Skin changes with age, more tags form |
| People with Obesity | More skin folds and friction |
| Pregnant Women | Hormone changes and skin stretching |
| People with Diabetes | High insulin affects skin growth |
| People with Family History | Genes that increase risk of tags |
Can Skin Tags Be Prevented?
It is hard to prevent skin tags completely. But some tips may help reduce them:
- Keep skin dry, especially in folds
- Maintain a healthy weight to reduce folds
- Wear loose clothing to reduce rubbing
- Avoid jewelry that rubs skin
- Manage diabetes and other health conditions
These steps can lower the chance of skin tags forming.
When to See a Doctor
Skin tags are harmless. But see a doctor if:
- The tag changes color or grows quickly
- It bleeds or becomes painful
- You want it removed for comfort or looks
A doctor can check the tag and remove it safely if needed.
Summary
Skin tags are small, harmless skin growths. They form when skin rubs together or changes due to age, weight, or hormones. Genetics and health conditions like diabetes also play a role. Skin tags usually appear where skin folds or rubs. While they cannot be fully prevented, keeping skin dry and healthy helps. If skin tags bother you, a doctor can remove them safely.
Understanding what causes skin tags helps you take care of your skin. Remember, skin tags are normal and common. There is no need to worry about them most of the time.
