Noticing a new bump on your skin can be confusing, especially when you’re trying to figure out whether it’s a skin tag vs mole or another type of skin lesion that looks similar. In many cases, both are common and often harmless, yet they develop for different reasons and can behave differently over time. Because of these differences, understanding what sets them apart can make a big difference. As a result, you gain more confidence in recognising what’s normal for your skin, when to keep an eye on a change, and when it might be helpful to get a professional assessment.
What are skin tags?
Skin tags, medically known as acrochordons, are small, soft, benign growths that sit on the skin’s surface. They often hang from a thin stalk and are usually flesh-coloured or slightly darker. Their texture is soft and movable when touched.
They tend to appear in places where skin rubs against skin or clothing, and as a result, they are most commonly found in areas such as:
- The neck
- Underarms
- Eyelids
- Under the breasts
- The groin
Skin tags are not infectious. They are more common in adults, especially those experiencing hormonal shifts, insulin resistance, or weight changes.
Skin tags vs moles: what are moles?
Moles, or melanocytic naevi, are pigmented lesions formed when melanocytes cluster in one area. Unlike skin tags, moles can be either flat or raised. Their colour ranges from pink to brown, dark brown, or even black.
Moles may appear at birth or develop over time. Most adults have between 10 and 40 moles. Many remain unchanged for years, while others may evolve gradually. Although most are harmless, certain types can develop into melanoma, a serious form of skin cancer.

Why do skin tags vs moles appear?
Skin tags
Skin tags often develop due to friction, weight changes, hormones, or metabolic conditions. Some people are also genetically prone to developing them.
Moles
Moles form when melanocytes grow together in clusters. Sun exposure, genetics, puberty, and pregnancy can all influence their appearance. Frequent sunburns may increase the number of moles and raise the risk of melanoma in some individuals.
When should you be concerned?
Both skin tags and moles are usually harmless. However, any noticeable change in a mole should be assessed by a professional. Look for:
- Changes in colour, shape, or size
- Multiple colours within one mole
- Bleeding, itching, or sudden irritation
- Rapid growth
The ABCDE rule for mole monitoring
A – Asymmetry
B – Border irregularity
C – Colour variation
D – Diameter larger than 6mm
E – Evolving over time
Skin tags never turn into cancer, but they may become irritated or bleed if caught on jewellery or clothing.

Skin tag removal
- Common options include:
- Cryotherapy
- Cauterisation
- Ligation

These procedures are quick and generally considered cosmetic.
