What Are Skin Tags?
Skin tags, medically known as acrochordons, are small, benign growths that form on the surface of the skin. They are typically soft, flesh-colored or slightly darker and often appear attached to the skin by a thin stalk called a peduncle. Skin tags are non-cancerous and usually painless, although they can become irritated if rubbed or twisted.
These growths vary in size from 1–2 millimeters to several centimeters. While they may look concerning, skin tags are considered harmless and are extremely common in adults.
How Common Are Skin Tags? (Statistics & Prevalence)
Skin tags are one of the most common dermatological conditions worldwide.
Key statistics:
- Approximately 50–60% of adults will develop at least one skin tag during their lifetime
- More common after the age of 40
- Affect men and women equally
- Prevalence increases significantly in people with overweight or obesity
- Up to 70% of people with type 2 diabetes may develop skin tags
- Pregnant women have a higher incidence due to hormonal changes
What Do Skin Tags Look Like?
Skin tags have distinct visual characteristics:
- Soft and smooth texture
- Flesh-colored, pink, brown or slightly darker
- Oval or round shape
- Can be flat or hanging
- Usually painless unless irritated
They should not bleed, ulcerate or change rapidly. Any skin growth that shows sudden color change, bleeding or pain should be evaluated by a doctor.
Common Areas Where Skin Tags Appear
Skin tags tend to form in areas where skin rubs against skin or clothing, including:
- Neck
- Armpits (underarms)
- Groin area
- Inner thighs
- Eyelids
- Under breasts
- Upper chest
- Back folds
Friction and moisture play a significant role in their development.
What Causes Skin Tags?
The exact cause of skin tags is not fully understood but several contributing factors have been identified:
1. Friction
Repeated skin-to-skin or skin-to-fabric contact stimulates excess skin growth.
2. Hormonal Changes
Hormonal fluctuations during pregnancy, menopause or endocrine disorders can trigger skin tags.
3. Insulin Resistance
Skin tags are strongly associated with:
- Type 2 diabetes
- Metabolic syndrome
- Prediabetes
They may act as a visible marker of insulin resistance.
4. Genetics
Some people inherit a tendency to develop skin tags.
5. HPV (Human Papillomavirus)
Certain studies suggest low-risk HPV strains may contribute to skin tag formation, although this remains controversial.
Risk Factors for Developing Skin Tags
You may be more likely to develop skin tags if you:
- Are overweight or obese
- Have diabetes or insulin resistance
- Are pregnant
- Have a family history of skin tags
- Experience frequent skin friction
- Have hormonal disorders (PCOS, thyroid imbalance)
Are Skin Tags Dangerous?
Skin tags are not dangerous and do not turn into cancer. But they can cause:
- Cosmetic concerns
- Irritation or bleeding if caught on jewelry or clothing
- Psychological discomfort
Medical attention is recommended if a skin growth:
- Bleeds without injury
- Grows rapidly
- Changes color
- Becomes painful

Diagnosis: How Are Skin Tags Identified?
Skin tags are usually diagnosed by visual examination. In rare cases, a dermatologist may perform a biopsy if the lesion looks atypical. No blood tests or imaging are usually required.
Medical Treatment Options for Skin Tags
1. Cryotherapy
Freezing the skin tag using liquid nitrogen.
2. Cauterization
Burning the skin tag using electrical energy.
3. Surgical Excision
Cutting off the skin tag with sterile instruments.
These procedures are quick, low-risk and often done in a single visit.
Can You Remove Skin Tags at Home? (Home Remedies)
Many people search for natural or home remedies. While medical removal is safest, the following methods are commonly discussed:
⚠️ Important Safety Note
Home removal carries risks such as infection, bleeding and scarring. Never attempt removal if the skin tag is:
- Bleeding
- Large
- Darkly pigmented
- Located on eyelids or genitals
Popular Home Remedies (With Limited Evidence)
1. Tea Tree Oil
- Known for antimicrobial properties
- May dry out small skin tags over time
2. Apple Cider Vinegar
- Acidic nature may break down tissue
- Can cause skin irritation or burns
3. Banana Peel
- Contains antioxidants
- Mostly anecdotal evidence
4. Dental Floss Ligation
- Cutting off blood supply
- High risk if done improperly
⚠️ Always consult a professional before trying any home method.
Over-the-Counter Skin Tag Removal Products
Pharmacies sell:
- Skin tag freezing kits
- Topical solutions
- Tag bands
These may work for very small skin tags, but results vary. Incorrect use can lead to scarring or infection.
Do Skin Tags Come Back After Removal?
Yes, skin tags can recur, especially if underlying risk factors remain.
Reasons for recurrence:
- Ongoing friction
- Weight gain
- Hormonal imbalance
- Insulin resistance
Removing one skin tag does not prevent new ones from forming elsewhere.
Prevention Tips: How to Reduce Skin Tag Formation?
While not always preventable, these steps may reduce risk:
- Maintain a healthy weight
- Control blood sugar levels
- Reduce skin friction
- Wear loose-fitting clothing
- Practice good skin hygiene
- Treat hormonal imbalances
Skin Tags and Diabetes: What’s the Link?
Multiple studies show a strong association between multiple skin tags and:
- Insulin resistance
- Type 2 diabetes
- Metabolic syndrome
Doctors sometimes recommend blood sugar testing for patients with numerous skin tags, especially on the neck.
Skin Tags During Pregnancy
Skin tags are common during pregnancy due to:
- Hormonal changes
- Weight gain
- Increased friction
Most pregnancy-related skin tags shrink or disappear after childbirth.
Psychological and Cosmetic Impact
Although harmless, skin tags can affect:
- Self-esteem
- Body image
- Social confidence
Removal for cosmetic reasons is valid and commonly requested.
Myths and Misconceptions About Skin Tags
