Introduction

Skin tags, also known as acrochordons, are small, benign growths that commonly appear on areas of the body where skin rubs against skin or clothing. While they are generally harmless, many people find them bothersome, especially if they appear in visible areas like the neck, face, or underarms. If you've noticed an increase in skin tags, you might be wondering why they are developing and whether there’s anything you can do to prevent them.

In this blog, we'll explore the common causes of skin tags, the risk factors that contribute to their development, and what you can do to manage them.

What Are Skin Tags?

Skin tags are soft, flesh-coloured growths that hang off the skin by a small stalk. They are made up of loose collagen fibres, fat cells, and blood vessels, all covered by a thin layer of skin. While they can appear anywhere on the body, they are most commonly found in areas where the skin folds or experiences frequent friction, such as:

• Neck
• Armpits
• Groin
• Eyelids
• Under the breasts

Skin tags are usually small, ranging from 1 to 5 millimetres in diameter, but they can grow larger over time. Though they are harmless and non-cancerous, many people choose to remove skin tag for cosmetic reasons or because they become irritated by clothing or jewellery.

Common Causes of Skin Tags

Several factors can contribute to the development of skin tags. Understanding these causes can help you identify why you might be getting them and what you can do to reduce their occurrence.

Friction and Skin Rubbing

One of the most common causes of skin tags is friction. When the skin rubs against itself or clothing. It can cause irritation and inflammation, leading to the formation of skin tags. This is why skin tags often appear in areas like the neck, underarms, and groin. Where skin folds and creases are more common.

• Clothing: Tight or rough fabrics can create friction, increasing the likelihood of developing skin tags.
• Jewelry: Necklaces, bracelets, or other accessories that rub against the skin can also contribute to the formation of skin tags.

Age and Hormonal Changes

As we age, our skin changes, and so does its tendency to develop skin tags. Middle-aged and older adults are more likely to develop skin tags due to the natural aging process. Which can lead to changes in skin elasticity and collagen production. Additionally, hormonal changes can also play a role:

• Pregnancy: Hormonal fluctuations during pregnancy can increase the likelihood of developing skin tags, particularly on the neck, underarms, and breasts.
• Menopause: Women going through menopause may notice an increase in skin tags due to changes in hormone levels.

Genetics

Genetics can play a significant role in whether or not you develop skin tags. If your parents or close relatives have skin tags, you may be more prone to developing them as well. This genetic predisposition often determines not only whether you get skin tags but also where they are likely to appear on your body.

• Family History: If skin tags run in your family, there’s a higher chance you’ll develop them as well, especially as you age.

Obesity and Weight Gain

There is a strong correlation between obesity and the development of skin tags. Excess body weight can lead to increased friction, particularly in areas where skin folds or creases. This constant friction can contribute to the formation of skin tags over time.

• Skin Folds: Individuals with higher body mass are more likely to have skin folds, which can create the perfect environment for skin tags to develop.

Insulin Resistance and Diabetes

Research has shown a connection between skin tags and insulin resistance, a condition where the body's cells become less responsive to insulin. Insulin resistance can lead to higher blood sugar levels, which in turn can contribute to the development of skin tags. People with insulin resistance or type 2 diabetes are more likely to develop skin tags, particularly in areas like the neck, armpits, and groin.

• Diabetes: If you have diabetes or are at risk of developing it, you may be more prone to skin tags.

Human Papillomavirus (HPV)

Some studies suggest a possible link between skin tags and certain strains of the human papillomavirus (HPV). HPV is a virus that can cause warts and other skin growths, and it’s believed that certain strains might also contribute to the development of skin tags.

• HPV Infection: While the link between HPV and skin tags isn’t fully understood, it’s possible that the virus could play a role in their formation.

Hormonal Disorders

Certain hormonal disorders, such as polycystic ovary syndrome (PCOS) or thyroid imbalances, can increase the likelihood of developing skin tags. These conditions can cause changes in skin health and the body’s overall hormonal balance, leading to the formation of skin tags.

• PCOS: Women with PCOS may experience higher levels of androgens, which can contribute to the formation of skin tags.

Immune System Responses

An overactive or weakened immune system might also contribute to the development of skin tags. For instance, individuals with autoimmune conditions or those who are immunosuppressed may be more prone to skin growths, including skin tags.

• Immune System Factors: Changes in immune function can influence skin health and may contribute to the formation of skin tags.

Can You Prevent Skin Tags?

While it may not be possible to prevent skin tags entirely, there are steps you can take to reduce the risk of developing them:

• Maintain a Healthy Weight: By managing your weight and reducing skin folds, you can decrease the friction that leads to skin tags.
• Wear Loose-Fitting Clothing: Avoid tight clothing that can create friction, especially in areas prone to skin tags.
• Practice Good Hygiene: Keeping your skin clean and dry can help reduce the risk of irritation and skin tag formation.
• Monitor Hormonal Health: If you have a hormonal disorder, work with your healthcare provider to manage it effectively and reduce the risk of skin tags.

When to See a Doctor

While skin tags are usually harmless, there are times when you should consult a doctor:

• The skin tag is painful, bleeding, or changing in appearance.
• You have multiple skin tags that are increasing in number.
• You’re unsure if the growth is a skin tag or something more serious.
• The skin tag is in a sensitive area, such as near the eyes or genitals.

A dermatologist can assess the skin tag and recommend the best course of action, whether it’s removal or simply monitoring it.

Conclusion: Understanding and Managing Skin Tags

Skin tags are common, especially as we age or experience hormonal changes. While they are generally harmless, understanding what causes them can help you manage and reduce their occurrence. Whether it’s due to friction, genetics, weight gain, or other factors, there are steps you can take to minimize your risk of developing skin tags. If you’re concerned about skin tags or notice any changes in their appearance, it’s always a good idea to consult with a healthcare professional for guidance.
