Skin tags, medically known as acrochordons, are benign, small, soft growths that project from the skin. They are incredibly common, and many people will develop at least one skin tag in their lifetime. If you’ve noticed these little flaps of skin and are wondering “Why Do I Have Skin Tags?”, you’re not alone. While they are harmless from a medical perspective, their appearance and location can sometimes be bothersome. This article will delve into the reasons behind skin tag development, their symptoms, and what you can do about them.
What Exactly Are Skin Tags?
Skin tags are essentially extra pieces of skin that grow out from the surface. They are composed of collagen and blood vessels, covered by an outer layer of skin. Typically, they are small, ranging from just a millimeter to about a centimeter in size, though they can occasionally grow larger. Skin tags are characteristically found in areas where skin rubs against skin, such as the folds and creases of the body. Common locations include:
- Armpits
- Groin area
- Neck
- Eyelids
- Under the breasts
- Anus
- Thighs
It’s estimated that around half of all adults will develop skin tags at some point in their lives. While they are more prevalent with age, anyone can get them.

Symptoms of Skin Tags: What to Look For
In most instances, skin tags are asymptomatic, meaning they don’t cause any pain or discomfort. Often, people are simply aware of them due to their appearance or when they are accidentally touched. However, skin tags can become problematic if they are located in areas where they are frequently rubbed or irritated. This can lead to:
- Soreness: Friction from clothing, jewelry, or even just skin rubbing against skin can make a skin tag tender and sore.
- Bleeding: Irritation can also cause a skin tag to bleed, particularly if it gets caught on something sharp or is repeatedly rubbed.
Visually, skin tags are distinct from other skin lesions like warts. They are typically identified by their stalk-like structure that attaches them to the skin. Warts, in contrast, tend to be flatter and have a rougher surface.
Unpacking the Causes: Why Do Skin Tags Develop?
The precise cause of skin tags remains somewhat of a medical mystery. It’s likely a combination of factors, both lifestyle and genetic, contribute to their development. For many individuals, skin tags appear without any clear trigger. However, there are some recognized associations and risk factors:
- Skin Friction: The most widely accepted theory is that skin tags develop due to friction. Areas where skin repeatedly rubs together are prime locations for skin tag formation. This explains why they are common in skin folds.
- Overweight and Obesity: People who are overweight or obese are significantly more prone to developing skin tags. This is likely due to increased skin folds and areas of friction.
- Diabetes: Diabetes and insulin resistance are linked to a higher incidence of skin tags. The exact connection is still being researched, but it may involve growth factors and skin cell proliferation.
- Pregnancy: Hormonal changes during pregnancy can increase the likelihood of skin tags. Fortunately, skin tags that appear during pregnancy often resolve on their own after childbirth.
- Age: Skin tags become more common as people age. This could be related to changes in skin elasticity and increased skin folds over time.
- Genetics: There is likely a genetic predisposition to developing skin tags. If skin tags run in your family, you may be more likely to get them yourself.
- Skin Conditions: Conditions like Birt-Hogg-Dube syndrome and polycystic ovary syndrome (PCOS) have been associated with an increased risk of skin tags.
It’s important to remember that developing skin tags is not necessarily a sign of an underlying health problem, but certain conditions can increase your susceptibility.
When to Consult a Doctor
While skin tags are generally harmless, it’s always prudent to consult your doctor if you notice any new growth on your skin. This is crucial for several reasons:
- Accurate Diagnosis: A doctor can confirm whether the growth is indeed a skin tag and rule out other skin conditions, including skin cancer. It’s essential to have any new or changing skin lesions evaluated by a medical professional.
- Skin Cancer Detection: Though rare, some skin cancers can mimic benign growths. A doctor can perform a proper examination to ensure there are no signs of malignancy.
- Removal Options: If a skin tag is bothersome, painful, or you wish to have it removed for cosmetic reasons, your doctor can advise on safe and effective removal methods.
Diagnosing Skin Tags
Diagnosing skin tags is typically straightforward. A doctor can usually identify a skin tag simply by visually examining it. They may ask about your medical history and any symptoms you’ve experienced. In most cases, no further tests or scans are needed for diagnosis.
Skin Tag Removal: Treatment Options
From a medical standpoint, there’s usually no need to remove skin tags. They pose no health risks. However, if a skin tag is causing irritation, discomfort, or you find it aesthetically displeasing, removal is a viable option. It’s generally not recommended to attempt to remove skin tags yourself at home, as this can lead to bleeding, infection, or incomplete removal.
Medical professionals can remove skin tags using several methods:
- Cryotherapy (Freezing): Liquid nitrogen is used to freeze the skin tag, causing it to eventually fall off.
- Excision (Cutting): The skin tag is surgically cut off using sterile scissors or a scalpel.
- Hyfrecation (Burning): An electrical current is used to burn off the skin tag.
The best removal method will depend on the size and location of the skin tag. Your doctor may refer you to a dermatologist (skin specialist) for removal, particularly if the skin tag is in a sensitive area or if there are multiple skin tags to be removed.
Can Skin Tags Be Prevented?
Unfortunately, there’s no guaranteed way to prevent skin tags entirely. However, you can take steps to reduce your risk:
- Maintain a Healthy Weight: Managing your weight through a balanced diet and regular exercise can help reduce skin folds and friction, potentially lowering the likelihood of skin tags.
- Manage Diabetes: If you have diabetes, proper blood sugar control may help reduce the risk of skin tags.
- Minimize Skin Friction: Wearing loose-fitting clothing in areas prone to skin tags can help minimize friction.

Skin tags are a common skin condition that is usually more of a cosmetic concern than a medical one. Understanding why they develop and knowing your options for removal can help you manage them effectively. If you have any concerns about skin tags, always consult with a healthcare professional for personalized advice and care.
