Quick Answer
Skin tags are small, soft, benign skin growths that commonly develop in areas where skin rubs against skin or clothing. They frequently appear on the neck, underarms, eyelids, groin, and skin folds. Although skin tags are usually harmless, some people choose to remove them for cosmetic reasons, irritation, or discomfort.
What Is a Skin Tag?
A skin tag is a small, non-cancerous growth of skin that typically hangs from the surface by a thin stalk. Skin tags are common in adults and often develop in areas exposed to friction, such as the neck, underarms, eyelids, and groin.
What Causes Skin Tags?
Skin tags are believed to develop due to a combination of skin friction, genetics, hormonal influences, aging, and metabolic factors. They often occur in areas where skin folds repeatedly rub together.
How Are Skin Tags Removed?
Skin tags can be removed through professional treatments such as cryotherapy, surgical excision, electrocautery, or ligation. The most appropriate method depends on the location, size, and characteristics of the skin tag.
KEY TAKEAWAYS

What Are Skin Tags?
Skin tags are one of the most common benign skin growths seen in dermatology. The medical term for a skin tag is:
“Acrochordon” These growths develop on the skin surface and are attached by a narrow stalk of tissue. Skin tags can appear:
- Individually
- In small groups
- In clusters
They may range from:
- A few millimeters in size
- Several centimeters in larger cases
Most skin tags are:
- Soft
- Flexible
- Flesh-colored
- Painless
- Non-cancerous
Because they are so common, skin tags account for a significant number of routine dermatology consultations.
What Is a Skin Tag Made Of?
Understanding the structure of a skin tag helps explain why it behaves differently from other skin growths. A typical skin tag contains:
- Collagen fibers
- Blood vessels
- Loose connective tissue
- Epidermal skin cells
These components are covered by normal skin tissue. Unlike cancers or infections, skin tags do not typically invade surrounding tissues.
Why Do Skin Tags Hang From the Skin?
Most skin tags are connected to the skin by a narrow stalk called a peduncle. This characteristic appearance often helps healthcare professionals distinguish skin tags from other lesions.
Who Gets Skin Tags?
Skin tags are extremely common. Research suggests that many adults will develop at least one skin tag during their lifetime.
Age: Skin tags become more common with increasing age. Although they can occur in younger individuals, they are more frequently observed in middle-aged and older adults.
Genetics: Family history appears to influence susceptibility. Some individuals naturally develop more skin tags than others.
Men and Women: Skin tags affect both men and women. Current evidence suggests they occur in both sexes at relatively similar rates.
Pregnancy: Some individuals notice increased skin tag development during pregnancy.
Hormonal changes may contribute to this tendency.
What Causes Skin Tags?
One of the most frequently searched questions is:
"What causes skin tags?"
Although researchers do not fully understand every mechanism involved, several contributing factors have been identified.
Friction and Skin Rubbing
The strongest evidence supports friction as a major contributing factor. Skin tags commonly occur in areas where:
- Skin touches skin
- Clothing repeatedly rubs against skin
- Moisture accumulates
Examples include:
- Neck folds
- Underarms
- Groin folds
- Under the breasts
This explains why skin tags often develop in high-friction locations.
Hormonal Influences
Hormones may influence skin tag development. This may help explain why skin tags sometimes appear during:
- Pregnancy
- Hormonal fluctuations
- Certain metabolic conditions
Evidence Strength: Grade C
Skin Tags and Genetics
Some people appear genetically predisposed to developing skin tags. A family history of multiple skin tags may increase likelihood. Evidence Strength:
Grade C
Skin Tags and Aging
Skin tags become more common as skin changes over time. Age-related alterations in skin structure may contribute to their development. Evidence Strength:
Grade B
Metabolic Associations
Research has identified associations between skin tags and:
- Obesity
- Insulin resistance
- Metabolic syndrome
- Type 2 diabetes
However, it is important to understand that having a skin tag does not automatically mean an individual has an underlying medical condition. Evidence Strength:
Grade B
Why Do Skin Tags Develop on the Neck?
Another highly searched topic is: "What causes skin tags on the neck?" The neck is one of the most common locations for skin tags.
Constant Friction
The neck experiences repeated movement and skin contact throughout the day.
Potential contributors include:
- Skin folds
- Shirt collars
- Jewelry
- Neck movement
Moisture and Heat
Warm and moist environments may increase friction and irritation.
Weight-Related Skin Folds
Additional skin folds can increase contact between skin surfaces, potentially contributing to skin tag formation.
Skin Tags on the Neck
Neck skin tags often appear as:
- Small flesh-colored bumps
- Hanging skin growths
- Soft, movable lesions
Most are:
- Benign
- Painless
- Slow-growing
However, irritation may occur when they catch on:
- Clothing
- Chains
- Razors
Skin Tag on Eyelid
Eyelid skin tags are another common reason people seek dermatological advice. Because the eyelid is a highly visible area, even small lesions can cause concern.
What Does an Eyelid Skin Tag Look Like?
Common characteristics include:
- Tiny soft growths
- Skin-colored appearance
- Smooth surface
- Narrow stalk attachment
Why Do Eyelid Skin Tags Develop?
Potential contributing factors include:
- Friction from blinking
- Aging
- Genetics
- Individual skin characteristics
Special Considerations
The eyelid is a delicate anatomical structure. For this reason, self-removal of eyelid skin tags is generally discouraged. Professional assessment is often the safest approach.
Common Locations of Skin Tags
Although neck and eyelid skin tags receive significant search interest, skin tags can occur almost anywhere. Common locations include:
- Neck
- Eyelids
- Underarms
- Groin
- Under the breasts
- Upper chest
- Back
- Around the anus
- Genital region
Different locations may influence treatment options and removal methods.
Symptoms and Appearance
Most skin tags produce no symptoms. Common features include:
- Soft texture
- Flesh-colored appearance
- Small stalk attachment
- Slow growth
Possible symptoms include:
- Irritation from clothing
- Twisting discomfort
- Cosmetic concerns
- Snagging during shaving
Skin tags usually do not cause:
- Significant pain
- Ulceration
- Persistent bleeding
- Systemic symptoms
These findings may indicate a different condition and warrant medical evaluation.
Are Skin Tags Dangerous?
One of the most common concerns people have after discovering a skin tag is whether it could be dangerous. In most cases, skin tags are:
- Benign
- Non-cancerous
- Harmless
- Slow growing
Most skin tags do not become cancerous.
When a Skin Tag May Need Medical Evaluation
Although typical skin tags are harmless, professional assessment is recommended if a growth:
- Changes rapidly
- Develops irregular coloring
- Becomes painful
- Bleeds repeatedly
- Ulcerates
- Has an unusual appearance
A healthcare professional can determine whether the lesion is truly a skin tag or another skin condition.
Clinical Perspective
The greatest risk associated with skin tags is often misdiagnosis rather than the skin tag itself.
