What Causes Skin Tags: Understanding These Common Growths

Skin tags are small, soft skin growths that commonly appear on areas of the body where skin rubs against skin or clothing. While generally harmless, understanding their causes can help with prevention and management.

What Are Skin Tags?

Skin tags, medically known as acrochordons, are benign skin growths that typically occur in skin folds or areas of friction. They are usually small, ranging from 1-5 mm in size, though they can grow larger. Skin tags are often flesh-colored or slightly darker and have a soft, smooth texture.

Common Causes of Skin Tags

1. Friction and Skin Rubbing

The most common cause of skin tags is friction. Areas where skin rubs against skin or clothing are prone to developing these growths. Common locations include:

Neck
Armpits
Groin area
Under breasts
Eyelids

2. Hormonal Changes

Hormonal fluctuations can increase the likelihood of developing skin tags. This is why they are often associated with:

Pregnancy
Menopause
Polycystic Ovary Syndrome (PCOS)

3. Insulin Resistance

Individuals with insulin resistance or type 2 diabetes may be more prone to developing skin tags. This is likely due to the effect of insulin on skin cell growth and division.

4. Genetics

There appears to be a genetic component to skin tag development. If your parents or siblings have skin tags, you may be more likely to develop them as well.

5. Obesity

Excess body weight can increase the likelihood of skin tag formation. This is partly due to increased skin friction and partly due to hormonal changes associated with obesity.

6. Aging

As we age, our skin becomes looser and more prone to developing skin tags. This is why they are more common in older adults.

Are Skin Tags Related to PCOS?

For individuals with Polycystic Ovary Syndrome (PCOS), skin tags can be a common occurrence. The hormonal imbalances and insulin resistance associated with PCOS can contribute to the development of skin tags. If you have PCOS and notice an increase in skin tags, it's worth discussing with your healthcare provider as part of your overall PCOS management plan.

Prevention and Management

While it's not always possible to prevent skin tags, some strategies may help reduce their occurrence:

Maintain a healthy weight
Manage insulin levels through diet and exercise
Keep skin folds clean and dry
Wear loose-fitting clothing to reduce friction

If skin tags are bothersome, they can be safely removed by a healthcare professional. However, it's important to note that removal is typically considered cosmetic and may not be covered by insurance.

When to See a Doctor

While skin tags are generally harmless, it's important to consult a healthcare provider if you notice:

Rapid growth or changes in appearance
Bleeding or pain
An unusual number of skin tags appearing suddenly

These could be signs of other skin conditions that require medical attention.

Conclusion

Understanding what causes skin tags can help you manage and potentially prevent their occurrence. While they're typically harmless, they can be a nuisance. If you're concerned about skin tags, especially if you have PCOS or other health conditions, don't hesitate to discuss them with your healthcare provider. Remember, maintaining overall health through a balanced diet, regular exercise, and proper skincare can go a long way in managing various skin conditions, including skin tags.
