Skin tags are small, soft growths that often appear on areas of the body where skin rubs against skin or clothing. Though usually harmless, they can be unsightly and occasionally uncomfortable. Understanding what causes skin tags, how to prevent them, and the safest ways to remove them is essential for maintaining healthy skin.
What Are Skin Tags?
Skin tags, medically known as acrochordons, are benign skin growths composed of collagen fibres and blood vessels. They often appear as small, flesh-coloured or slightly darker protrusions, typically on the neck, underarms, eyelids, groin, or other areas where skin folds. While they do not pose a health risk, many people seek their removal for cosmetic reasons or to prevent irritation.
Common Causes of Skin Tags
Several factors contribute to the development of skin tags:
Friction and Skin Irritation
Areas of the body where skin frequently rubs against skin or clothing are prone to developing skin tags. This is why they often appear on the neck, underarms, and groin.
Genetics
A family history of skin tags can increase the likelihood of developing them. Some people may be more predisposed to these growths due to inherited skin traits.
Hormonal Changes
Hormonal fluctuations, particularly during pregnancy or conditions like insulin resistance, can contribute to skin tag formation.
Age and Weight
Skin tags are more common in middle-aged and older adults, and people who are overweight are more likely to develop them due to increased skin folds and friction.
Medical Conditions
Certain health conditions, including type 2 diabetes, metabolic syndrome, and obesity, have been linked to a higher incidence of skin tags.
How to Prevent Skin Tags
While not all skin tags can be prevented, there are several steps you can take to reduce the risk:
Maintain a Healthy Weight
Since friction plays a significant role in skin tag formation, maintaining a healthy weight can reduce skin folds and rubbing.
Keep Skin Dry and Clean
Moist, sweaty areas are more prone to friction-related skin tags. Using powder or keeping folds dry can help minimise growths.
Wear Comfortable Clothing
Loose-fitting clothing can reduce skin friction, especially in areas like the underarms, waist, and thighs.
Monitor Hormonal Health
Managing conditions like insulin resistance and maintaining hormonal balance can help reduce the risk of skin tag development.
Safe Removal Options
While some people attempt to remove skin tags at home using over-the-counter remedies or DIY methods, these can lead to infection, bleeding, or scarring. Consulting a professional ensures safe and effective removal.
Medical Procedures
Professional skin tag removal can involve various methods, including:
- Cryotherapy: Freezing the skin tag off with liquid nitrogen.
- Excision: Cutting the skin tag off with a sterile scalpel or scissors.
- Electrocautery: Using heat to burn off the skin tag.
- Ligation: Tying off the skin tag at the base to cut off blood flow, causing it to fall off.
When considering removal, it’s important to know who can remove skin tags, such as dermatologists or trained healthcare professionals, to ensure the procedure is done safely.
Aftercare Tips
Post-removal care is crucial to prevent infection and promote healing. Keep the area clean, avoid picking at scabs, and monitor for any signs of infection such as redness, swelling, or pus.
When to See a Doctor
Most skin tags are harmless, but you should consult a doctor if:
- A growth changes colour, size, or shape
- It bleeds, itches, or becomes painful
- You have multiple skin tags appearing rapidly
Professional evaluation ensures that a suspicious growth is not a more serious skin condition.
Final Thoughts
Skin tags are a common skin concern that can be caused by friction, genetics, hormonal changes, and age. While they are typically harmless, preventing them through good skin care and healthy lifestyle choices can reduce their occurrence. If removal is desired, professional treatment is the safest approach, minimising the risk of infection or scarring. Understanding skin tags, their causes, and safe removal methods empowers you to maintain both the health and appearance of your skin.
