Skin tags are small, soft growths that hang off the skin by a thin stalk. These harmless flesh-colored or slightly darker bumps are incredibly common, affecting nearly half of all adults at some point in their lives. While they don’t pose any health risks, many people find skin tags bothersome or unsightly, leading them to seek removal options.
This article aims to provide a comprehensive overview of skin tags. It will explore what skin tags are, delve into their causes and risk factors, and discuss various diagnosis and treatment options available. By the end, readers will have a better understanding of these benign skin growths and how to manage them effectively.
What Are Skin Tags?
Skin tags, medically known as acrochordons, are small, soft, flesh-colored growths that hang off the skin by a thin stalk called a peduncle. These benign cutaneous growths are composed of loose fibrous tissue and are usually harmless. Skin tags are incredibly common, affecting nearly half of all adults at some point in their lives.
Definition
Skin tags are defined as small, soft excrescences of heaped up skin that are usually benign in nature. They are also referred to as fibroepithelial polyps or soft fibromas. Skin tags are not contagious, but individuals often have more than one and may find a crop has appeared in the same area.
Appearance
Skin tags typically appear as small, soft, skin-colored, brown, or even red ovoid growths that are often pedunculated and attached to a fleshy stalk. They can range in size from a few millimeters to several centimeters, with most measuring between 1 and 5 mm. The surface of a skin tag may be smooth or slightly wrinkled, and they are usually the same color as the surrounding skin or slightly darker.
Histologically, skin tags have an attenuated epidermis, a flattened basal cell layer, and often increased pigmentation. The extra mass is composed of loose fibrous tissue, and the lesion is connected to the skin by a narrow and thin pedicle. Skin tags may also contain blood vessels of various sizes in the dermal stroma.

Common locations
Skin tags tend to develop in areas where skin rubs against skin or clothing, particularly in skin folds or creases. The most common locations for skin tags include:
- Neck creases
- Armpits (axillae)
- Under the breasts
- Eyelids
- Groin area
- Upper chest (décolletage)
- Beneath the buttocks
- Anal area
- Vagina
These areas are more prone to skin tag development due to the increased likelihood of skin rubbing and friction. Skin tags are more likely to occur with weight gain or the expansion that occurs during pregnancy, as either of these can increase the likelihood of skin rubbing.
While skin tags can develop at any age, they are most common in middle-aged and older adults. The probability of developing skin tags increases after the fourth decade of life, with estimates suggesting that almost 50 to 60% of adults will develop at least one skin tag in their lifetime.
It is important to note that while skin tags are generally harmless, they may cause cosmetic concerns or functional issues if they catch on clothing or jewelry. If a skin tag becomes irritated, painful, or affects vision, it is advisable to consult a dermatologist for proper evaluation and treatment options.
Causes and Risk Factors
While the exact cause of skin tags remains unclear, several factors can contribute to their development. Understanding these risk factors can help individuals identify their susceptibility to developing these benign growths.
Genetics
Genetics play a significant role in the development of skin tags. Individuals with a family history of skin tags are more likely to develop them. Studies suggest that certain genetic factors may predispose individuals to the growth of these benign lesions.
Hormonal changes
Hormonal fluctuations, particularly those associated with pregnancy and menopause, can influence the development of skin tags. During pregnancy, elevated levels of estrogen and progesterone can lead to skin tags formation. Similarly, the hormonal changes that occur during menopause may contribute to the growth of these benign lesions.
Conditions such as polycystic ovary syndrome (PCOS), characterized by hormonal imbalances, are also associated with an increased risk of developing skin tags. The elevated androgen levels in PCOS can stimulate the growth of these benign tumors.

Obesity and diabetes
Obesity and diabetes are significant risk factors for the development of skin tags</primary keyword>. Individuals with a higher body mass index (BMI) are more prone to developing these growths. The increased skin folds and friction associated with obesity create an environment conducive to skin tag.
Insulin resistance, a hallmark of type 2 diabetes, is also linked to the growth of skin tags. High levels of insulin in the blood can stimulate the proliferation of skin cells, leading to the formation of these benign lesions.
Friction and skin rubbing
Friction and skin rubbing are common causes of skin tags. These growths often develop in areas where skin rubs against skin or clothing, such as the neck, underarms, and groin. The constant friction and irritation can trigger the growth of skin tags.
Tight clothing, jewelry, and certain physical activities that involve repetitive rubbing of the skin can also contribute to the development of these benign lesions. Minimizing friction and ensuring proper hygiene in areas prone to skin tags can help reduce their occurrence.
It is important to note that while these risk factors increase the likelihood of developing skin tags, not everyone with these factors will necessarily develop them. Additionally, the presence of skin tags does not always indicate an underlying health issue. However, if an individual notices a rapid increase in the number or size of skin tags, it is advisable to consult a healthcare professional to rule out any potential underlying conditions.
By understanding the causes and risk factors associated with skin tags, individuals can take proactive steps to minimize their occurrence and seek appropriate medical guidance when necessary. While skin tags are generally harmless, addressing the underlying risk factors can contribute to overall skin health and well-being.
Diagnosis and Treatment Options
Skin tags are typically diagnosed through a visual examination by a dermatologist or healthcare provider. During the examination, the doctor will assess the growth’s appearance, size, and location to determine if it is indeed a skin tag. In most cases, this visual inspection is sufficient for an accurate diagnosis.
However, in rare instances where the growth appears atypical or suspicious, the doctor may recommend a biopsy. This involves removing a small sample of the growth for further examination under a microscope to rule out any potential skin cancers or other concerning conditions.
Once diagnosed, skin tags do not require treatment unless they cause discomfort, irritation, or cosmetic concerns. If removal is desired, several options are available:
- Cryotherapy: This involves freezing the skin tag with liquid nitrogen, causing it to fall off within a few days.
- Electrocautery: An electric current is used to burn off the skin tag at its base.
- Surgical excision: The doctor numbs the area and uses surgical scissors or a scalpel to remove the skin tag. Stitches may be necessary for larger growths.
- Ligation: A thread is tied tightly around the base of the skin tag, cutting off its blood supply and causing it to fall off.
These procedures are generally quick, well-tolerated, and performed in a doctor’s office. Complications are rare but may include minor bleeding, infection, or scarring.
For those seeking at-home treatments, some over-the-counter products are available, such as skin tag removal creams or freezing kits. However, it is essential to exercise caution when using these products, as they may cause skin irritation or other adverse reactions. Additionally, attempting to remove skin tags at home using methods like cutting or tying off with string can lead to infection and is not recommended.
Natural remedies, such as applying tea tree oil or apple cider vinegar to the skin tag, have been suggested as potential at-home treatments. However, the effectiveness of these methods is not well-established, and they may cause skin irritation in some individuals.

Ultimately, the safest and most effective approach to skin tag removal is to consult with a dermatologist or healthcare provider. They can assess the growth, recommend the most appropriate treatment option, and perform the procedure in a sterile, controlled environment to minimize the risk of complications.
It is important to remember that while skin tags are generally harmless, any changes in their appearance, rapid growth, or the development of multiple new growths should prompt a medical evaluation to rule out any underlying health concerns.
Conclusion
Skin tags, while generally harmless, can be a source of discomfort and cosmetic concern for many individuals. Understanding their causes, risk factors, and available treatment options empowers people to make informed decisions about their skin health. By recognizing the influence of genetics, hormonal changes, and lifestyle factors on skin tag development, individuals can take proactive steps to minimize their occurrence and seek appropriate medical guidance when necessary.
To wrap up, the management of skin tags involves a combination of prevention and treatment strategies. From simple at-home care to professional medical procedures, there are various approaches to address these benign growths. While removal is not always necessary, consulting with a healthcare provider can help determine the best course of action for those seeking to eliminate skin tags. By staying informed and proactive, individuals can maintain healthy skin and address any concerns related to skin tags effectively.
