Is That Skin Tag Safe? Why Skin Tags Grow and What to Do Next

A skin tag is one of the most common and harmless skin growths doctors see. If you've noticed a small, soft piece of skin hanging from your neck, armpit, eyelid, or groin area, you're not alone. Millions of adults develop at least one skin tag in their lifetime.

But a common question is: Is that skin tag safe?
In most cases, the answer is yes. Still, it's important to understand why skin tags grow and when you should take the next step.

What Is a Skin Tag?

A skin tag (medical term: acrochordon) is a small, soft, flesh-colored or slightly darker growth that hangs off the skin. It is usually attached by a thin stalk.

Skin tags are:

• Soft and smooth (sometimes slightly wrinkled)
• Small (typically 1–5 mm, but can grow larger)
• Flesh-colored, tan, or slightly darker
• Painless (unless irritated)

They are non-cancerous (benign) growths. That means they are not skin cancer.

Is a Skin Tag Safe?

In the vast majority of cases, a skin tag is completely safe.

According to dermatology research and major medical organizations:

• Skin tags are benign growths
• They do not turn into cancer
• They do not spread to other parts of the body
• They usually do not require medical treatment

However, while most skin tags are harmless, it's important to make sure the growth truly is a skin tag and not something else. Some skin cancers or unusual moles can look similar, especially to the untrained eye.

You should have a doctor evaluate the growth if it:

• Changes color (especially black, purple, or very dark)
• Grows rapidly
• Bleeds without injury
• Becomes painful
• Has an irregular shape
• Develops crusting or open sores

Why Do Skin Tags Grow?

Doctors do not know the exact cause of every skin tag, but research shows several clear contributing factors.

1. Friction

The most common reason skin tags grow is skin rubbing against skin.

This explains why they often appear in:

• Neck folds
• Armpits
• Groin
• Under breasts
• Eyelids

Repeated friction may stimulate extra skin growth.

---

2. Insulin Resistance and Blood Sugar

There is a strong association between skin tags and insulin resistance, which is linked to:

• Prediabetes
• Type 2 diabetes
• Metabolic syndrome

People with multiple skin tags are statistically more likely to have insulin resistance. This does not mean skin tags cause diabetes, but they can sometimes be a visible clue.

If you have many skin tags, it may be worth discussing blood sugar testing with your doctor.

---

3. Hormonal Changes

Skin tags are more common during:

• Pregnancy
• Weight gain
• Middle age

Hormonal shifts may stimulate skin cell growth.

---

4. Genetics

If your parents have skin tags, you are more likely to develop them as well.

---

5. Weight and Body Composition

Skin tags are more common in people who:

• Are overweight or obese
• Have more skin folds

Again, friction and metabolic factors likely play a role.

---

Are Skin Tags Ever Dangerous?

A true skin tag is not dangerous. However, problems can occur if:

• It twists and loses blood supply (can become painful and dark)
• It gets caught on clothing or jewelry
• It bleeds from repeated irritation

Rarely, a growth that looks like a skin tag may actually be:

• A mole
• A wart
• Seborrheic keratosis
• Basal cell carcinoma (a type of skin cancer)

This is why evaluation is important if anything about the lesion seems unusual.

If you ever notice warning signs such as rapid growth, unexplained bleeding, or color changes, you should speak to a doctor promptly, as these could indicate something more serious.

---

Should You Remove a Skin Tag?

Medically speaking, most skin tags do not need to be removed.

Removal is usually done for:

• Cosmetic reasons
• Irritation
• Repeated bleeding
• Discomfort from friction

Safe Medical Removal Options

A healthcare provider may remove a skin tag using:

• Cryotherapy (freezing it off)
• Cauterization (burning it off safely)
• Snipping with sterile scissors
• Ligation (tying it off to cut blood supply)

These are quick, in-office procedures.

---

Should You Remove a Skin Tag at Home?

Many over-the-counter products claim to remove skin tags. However, medical experts generally advise caution.

You should not attempt home removal if:

• The growth is large
• It is on the eyelid or genital area
• You are unsure it is a skin tag
• You have diabetes or poor wound healing
• The lesion is dark or irregular

Home removal can lead to:

• Infection
• Heavy bleeding
• Scarring
• Misdiagnosis of a more serious condition

If you are unsure whether it is truly a skin tag, it's safer to have a clinician examine it first.

---

Can You Prevent Skin Tags?

There is no guaranteed way to prevent a skin tag, but you can reduce risk factors:

• Maintain a healthy weight
• Manage blood sugar levels
• Reduce skin friction when possible
• Keep skin clean and dry
• Wear loose-fitting clothing in friction-prone areas

If you have multiple skin tags, your doctor may recommend screening for metabolic conditions.

---

When to Speak to a Doctor

You should speak to a doctor if:

• You are unsure whether it's a skin tag
• The growth changes in size, shape, or color
• It becomes painful or infected
• It bleeds without clear cause
• You develop many new skin tags suddenly

While most skin tags are harmless, any rapidly changing skin lesion deserves medical attention. Early evaluation can rule out more serious conditions.

The Bottom Line: Is That Skin Tag Safe?

In most cases, yes — a skin tag is safe and benign.

They are common, especially in adults, and are usually caused by friction, genetics, hormonal changes, or metabolic factors like insulin resistance.

However:

• Not every growth is a skin tag
• Changes in appearance should be evaluated
• Large or irritated skin tags may need professional removal

Above all, if you notice signs that could indicate something serious — such as rapid growth, unexplained bleeding, dark discoloration, or pain — speak to a doctor promptly. Early evaluation is always the safest approach.

Most skin tags are harmless. But your health is worth confirming.
