Noticing clusters of skin tags on the neck, underarms, or other areas? While skin tags are harmless, they can sometimes signal underlying metabolic changes such as insulin resistance. At City Dermatology Clinic in London, our dermatologists often see this link during routine skin checks, especially in patients managing pre-diabetes, type 2 diabetes, or PCOS.
This guide explains why skin tags are linked to insulin resistance, what to look out for, and the best ways to manage both the skin and underlying health.
The Link Between Skin Tags and Insulin Resistance
Skin tags are common, but when they appear suddenly or in clusters, particularly on the neck, armpits, or chest, they can indicate changes in how the body processes insulin.
Insulin resistance happens when the body’s cells stop responding effectively to insulin, causing higher levels of insulin and glucose in the blood. These elevated levels can stimulate skin growth, increasing the likelihood of developing skin tags.
Areas where skin tags commonly appear
Patients with insulin resistance often notice skin tags forming in:
- The sides or back of the neck
- Underarms or inner thighs
- Beneath the breasts
- Around the groin
Why Insulin Resistance Causes Skin Tags
Insulin plays a role in regulating cell growth. When levels remain consistently high, the skin’s growth factors become overactive, leading to the formation of new skin tags, especially in areas where skin rubs together.
Associated conditions
Insulin resistance is often linked to:
- Type 2 diabetes
- Polycystic ovary syndrome (PCOS)
- Metabolic syndrome
Because of this, clusters of skin tags can sometimes be one of the first external signs of these underlying conditions.
Getting a Proper Diagnosis
If you’re noticing new or multiple skin tags, especially alongside symptoms like weight changes, fatigue, or darkened patches of skin (acanthosis nigricans), it’s worth getting checked.
In-clinic examination for skin tags
At City Dermatology Clinic, our dermatologists can quickly confirm whether the growths are skin tags and rule out other conditions. Many patients opt for same-day removal for comfort or cosmetic reasons.
Blood tests to check insulin and glucose levels
While the tags themselves aren’t harmful, your GP or endocrinologist may recommend blood tests to assess insulin, glucose, and HbA1c levels. Identifying insulin resistance early can help prevent more serious complications.
Treatment Options for Skin Tags
Skin tags don’t pose a health risk, but many patients choose skin tag removal for comfort or cosmetic reasons. At City Dermatology Clinic in Harley Street and Queen Street, London, we offer safe, same-day removal options tailored to the size and location of each tag.
Safe removal methods
- Cryotherapy: Freezing the skin tag with liquid nitrogen until it falls off naturally
- Cautery: Using a fine heated probe to seal and remove the tag instantly
- Minor surgical excision: For larger tags, a tiny surgical procedure under local anaesthetic ensures complete removal
Managing irritation or discomfort
If your tags are rubbing on clothing or jewellery, early removal prevents soreness or bleeding and keeps the skin smooth.
Improving Insulin Sensitivity
Treating the tags alone won’t stop new ones from forming if insulin resistance isn’t addressed. Supporting healthy insulin levels can reduce the likelihood of new tags appearing and improve overall health.
Diet and lifestyle changes
- Reducing refined sugars and processed foods
- Prioritising balanced meals with protein and fibre
- Staying active to improve insulin sensitivity
- Maintaining a healthy weight where possible
Medications and monitoring
For some patients, GPs or endocrinologists may recommend medication like metformin or regular monitoring to manage blood sugar and insulin levels effectively.
When to See a Dermatologist
If you’ve noticed clusters of new skin tags, or tags becoming irritated or bleeding, book an assessment. At City Dermatology Clinic, we combine safe removal with advice on preventing future irritation, and we’ll let you know if a GP check-up for metabolic health would be beneficial.
Appointments are available at both Harley Street and Queen Street clinics, with many patients choosing same-day removal during their consultation.
