Skin tags are small, soft, flesh-coloured growths that hang off the skin and look a bit like warts. They’re incredibly common and completely harmless, but what exactly causes them? In short, skin tags are typically caused by friction and skin rubbing against skin or clothing.
The Science Behind Skin Tags
To understand what causes skin tags, it’s important to first know what they are. Skin tags, medically known as acrochordons, are benign (non-cancerous) skin growths that consist of loose collagen fibres and blood vessels surrounded by skin. They’re essentially small pieces of hanging skin that can appear anywhere on the body, but are most common in areas where skin rubs against skin or clothing.
Common Causes of Skin Tags
While the exact cause of skin tags isn’t fully understood, several factors are known to contribute to their formation:
- Friction: Areas where skin rubs against skin or clothing are prime locations for skin tags.
- Hormonal changes: Pregnancy and hormonal imbalances can increase the likelihood of developing skin tags.
- Age: Skin tags become more common as we get older, particularly after the age of 50.
- Weight gain: Excess body weight can lead to increased skin folds and friction, promoting skin tag formation.
- Genetics: Some people may be more prone to developing skin tags due to their genetic makeup.
- Certain health conditions: Conditions like type 2 diabetes and metabolic syndrome may increase the risk of developing skin tags.
Identifying Skin Tags
Skin tags have distinct characteristics that set them apart from other skin conditions:
- Small, soft growths that hang off the skin
- Usually flesh-coloured, though they can be darker
- Typically painless, but may become irritated if rubbed frequently
- Common in areas like the neck, armpits, groin, under the breasts, and eyelids
- Can vary in size from a few millimetres to 5cm wide
Skin Tags vs Other Skin Conditions
It’s important to differentiate skin tags from other skin conditions. While skin tags are harmless, some growths may require medical attention. If you’re unsure about a skin growth, it’s always best to consult a dermatologist.
Prevention and Management of Skin Tags
While it’s not always possible to prevent skin tags, there are steps you can take to reduce your risk:
- Maintain a healthy weight to reduce skin-on-skin friction
- Wear loose-fitting clothing to minimize skin irritation
- Keep skin folds clean and dry
- Manage underlying health conditions like diabetes
If you have skin tags that are bothering you, it’s best to consult a healthcare professional for safe removal options. Never attempt to remove skin tags at home, as this can lead to bleeding, infection, or scarring.
When to Seek Medical Advice
While skin tags are generally harmless, there are instances when you should consult a doctor:
- If a skin tag changes colour, size, or shape
- If it bleeds or causes pain
- If you’re unsure whether a growth is a skin tag or something else
- If you have a large number of skin tags appearing suddenly
Understanding what causes skin tags can help you manage and prevent these common skin growths. While they’re harmless, skin tags can be a nuisance or cause cosmetic concerns for some people. Remember, your skin health is important, and there’s no need to live with bothersome skin conditions.
