Skin Tags vs Moles: What You Need to Know

When it comes to small skin growths like moles or skin tags, many people wonder whether they are harmless, cosmetic, or something that needs medical attention. At Skinoza Clinic in London, we regularly see clients who are unsure whether they have a skin tag or a mole, and what the safest way to remove it is. Understanding the difference between these two types of lesions is essential before deciding on any form of skin removal treatment.

In this guide, we’ll explain what skin tags and moles are, how to tell them apart, when you should consider removal, and the safest and most effective skin removal treatments available in London.

What Are Skin Tags?

Skin tags, medically known as acrochordons, are soft, small, flesh-coloured growths that hang off the skin. They are completely benign and usually cause no pain or discomfort. However, they can be irritating when rubbed by clothing, jewellery, or during shaving.

Common causes of skin tags

Skin tags tend to appear in areas where the skin folds or experiences friction, such as:

Neck
Armpits
Groin
Under the breasts
Eyelids

They are more common in people who are overweight, pregnant, or have diabetes, although anyone can develop them. Genetics can also play a role.

Appearance

Skin tags are:

Soft and moveable
Attached to the skin by a small stalk (peduncle)
Usually the same colour as your skin or slightly darker

Because of their harmless nature, skin tags don’t need to be removed for medical reasons, but many people choose removal for cosmetic or comfort purposes.

What Are Moles?

Moles, or naevi, are clusters of pigment-producing cells (melanocytes) that form visible spots on the skin. Most moles appear in childhood or adolescence and are generally harmless. However, unlike skin tags, moles have the potential to develop into melanoma, a type of skin cancer. This makes proper assessment by a medical professional important.

Appearance

Moles can be:

Flat or slightly raised
Round or oval in shape
Brown, tan, pink, or black in colour
Sometimes hairy

Moles can occur anywhere on the body, including areas not exposed to the sun.

When to be cautious

You should have a mole checked if it:

Changes shape, size, or colour
Develops irregular borders
Starts bleeding, itching, or crusting
Appears after the age of 30

If you notice these features, it’s best to consult a GP or dermatologist before considering removal.

Skin Tag vs Mole: How to Tell the Difference

Many people confuse moles and skin tags, especially when they appear in similar areas such as the neck or underarms. However, a few key differences can help distinguish them.

Feature	Skin Tag	Mole
Texture	Soft, smooth, hangs off skin	Flat or slightly raised
Colour	Flesh-coloured or light brown	Tan, brown, or black
Shape	Irregular, stalked	Round or oval
Growth	Caused by friction	Cluster of pigment cells
Cancer risk	Harmless	Rarely, can become cancerous

If you are uncertain, it’s always best to book a skin assessment at a professional clinic before attempting removal.

Can Skin Tags and Moles Be Removed Safely?

Yes — both skin tags and moles can be safely removed using medical or cosmetic procedures performed by trained specialists. The best method depends on the type, size, and location of the lesion.

At Skinoza Clinic in London, we offer advanced skin removal treatments designed to remove unwanted growths with precision and minimal discomfort.

Popular skin removal treatments include:

1. Cryotherapy

Cryotherapy uses liquid nitrogen to freeze and destroy unwanted tissue. It’s commonly used for skin tags and some superficial moles. The treated area may form a small scab and heal within a week or two.

2. Electrolysis (Thermo-coagulation)

Electrolysis is a highly effective method that uses a fine probe to apply controlled heat energy to the lesion, causing it to dry up and fall off naturally. It’s particularly effective for skin tags, thread veins, and milia.

3. Laser skin removal

Laser treatment targets pigmented lesions without damaging the surrounding skin. It’s ideal for small moles and pigmented marks that don’t require surgical excision.

4. Surgical excision

For deeper or larger moles, a minor surgical excision may be recommended. This is performed under local anaesthetic by a trained medical professional. The mole is removed entirely, and the tissue can be sent for histology if needed.

Why You Should Avoid DIY Skin Tag or Mole Removal

Although there are many home removal kits and online remedies available, removing skin tags or moles yourself is not recommended. Doing so can lead to:

Infection
Bleeding
Scarring
Incomplete removal
Missed diagnosis of a cancerous mole

Only a qualified clinician can confirm whether a lesion is safe to remove and which method is most suitable.

At Skinoza Clinic, every client is first assessed by an experienced practitioner to ensure that the growth is benign and suitable for cosmetic treatment.
