Have you ever noticed small, soft growths on your skin that seem to appear out of nowhere? These might be skin tags. Those tiny, flesh-coloured or slightly dark pedunculated growths that often show up around the neck, underarms, or in places where skin rubs together. While they’re generally harmless, understanding them is key to better skin health and overall well-being.

What are skin tags?

Skin tags, or acrochordons, are benign (non-cancerous) growths of skin that can vary in size, typically ranging from millimetres to a few centimetres. They’re often connected to the skin by a thin stem or peduncle, making them easy to spot. While skin tags are typically soft, they may sometimes feel a little rough. Though they’re often associated with aesthetic concerns, their presence is a signal from your skin about potential friction, hormonal changes, or other underlying factors.

What causes skin tags?

While the exact cause of skin tags is still under investigation, several factors can contribute to their development:

	Friction Frequent rubbing between skin surfaces is a major contributor, making skin tags more likely to appear in areas where the skin is prone to friction, such as the neck, eyelids, underarms or groin.
	Genetics Your genetic makeup can increase your likelihood of developing them with some people being genetically predisposed to skin tags.
	Hormonal changes Pregnancy, metabolic disorders, and insulin resistance have been linked to skin tag growth.
	Underlying health conditions Studies suggest a higher prevalence of skin tags in individuals with obesity, diabetes, or skin disorders like Hogg-Dubé syndrome.

Though skin tags are not dangerous, they can serve as a reflection of your skin’s health and its response to environmental and internal changes. Instead of just focusing on aesthetics, understanding how skin tags connect to your broader health can empower you to take a more proactive approach.

Repeated skin friction, whether from clothing, perspiration, or constant movement, can cause skin to react by producing skin tags. This is your body’s way of signalling that your skin is under stress. If you’re developing skin tags more frequently, it might be a good idea to look at your lifestyle and consider ways to reduce unnecessary friction on your skin.

When should you be concerned?

While most skin tags are harmless, certain signs warrant a professional evaluation by a dermatologist:

How can skin tags be treated?

If skin tags are causing discomfort or you simply don’t like their appearance, there are several removal options available, though many treatments are cosmetic rather than medically necessary. Removal should always be performed by a qualified dermatologist to ensure safety and minimise risks. Common procedures include:

	Cryotherapy Using liquid nitrogen to freeze it.
	Excision Using a scalpel to cut it off.
	Cauterisation Using heat to burn it off.
	Ligation Using a surgical thread to tie around the tag to reduce blood flow, and causing it to eventually drop off.

It’s important to avoid trying DIY methods, as these treatments can lead to infections, scarring or other complications.

Skin tags are a common occurrence, but they also serve as reminders to pay closer attention to our skin’s overall health. Too often, we focus solely on aesthetics, overlooking the fact that our skin is a vital organ that protects and reflects our well-being. Noticing changes like skin tags can be an opportunity to understand our body’s needs and adopt a more proactive approach to skin care.

Rather than viewing skin tags as just a cosmetic nuisance, consider them signals to assess your skin’s health. Regular monitoring, proper skincare, and consulting a dermatologist, when necessary, can help maintain not just the appearance but the overall well-being of your skin.
