Spotting a new mark on your skin can bring up a mix of questions. Is it a mole, or is it a skin tag? The two often look similar, yet they form for very different reasons and carry very different implications for your health. While skin tags are harmless overgrowths of skin, some moles need close attention because they may change over time. Knowing how to tell a skin tag from a mole is important for both health and peace of mind.
Many patients visit Lumine Dermatology & Laser Clinic asking the same question: “Do I have a skin tag or mole?” This confusion is understandable, since both are common and can appear in areas that are difficult to monitor closely. While most moles are harmless, some can carry risks, which is why distinguishing between the two is important. This guide explores the differences, explains the health implications, and outlines the treatment options available when you want clarity and care from a specialist.
Moles are clusters of pigment-producing cells known as melanocytes. These cells normally spread across the skin, but when they group together, they form a visible spot. Moles may be flat or slightly raised and their colour ranges from light brown to very dark. Some appear during childhood, while others develop later in life due to hormonal shifts or sun exposure.
Most moles remain stable and harmless throughout life. However, because they are linked to pigment, they need to be monitored for signs of change. An evolving mole that grows, changes colour, or bleeds should always be checked by a dermatologist. While the majority are benign, some can develop into melanoma, a serious type of skin cancer.
Skin tags are small, harmless pieces of tissue that develop on the surface of the skin. They often resemble tiny bumps or flaps that dangle slightly, which distinguishes them from moles that sit flat or raised against the skin. Most skin tags are the same shade as the surrounding skin, although in some cases, they can appear slightly darker. Because a thin stem of tissue connects them, they tend to move more freely when touched.
They commonly appear in spots where the skin creases or experiences friction, such as around the neck, under the arms, beneath the breasts, or on the eyelids. While they are not dangerous, skin tags can sometimes snag on clothing, jewellery, or razors, causing discomfort. Many people also decide to remove them when they feel self-conscious about their appearance, especially if the tags are in a visible location.
When comparing skin tag vs mole, the difference becomes clearer once you know what to look for. Moles are typically uniform in colour and either flat or raised within the skin. They do not dangle or move when touched. In contrast, a skin tag protrudes from the surface and is usually connected by a thin stalk, giving it a soft and mobile feel.
Moles can vary in size and shade, sometimes darkening after sun exposure. Skin tags remain relatively consistent in colour and are almost always small and flesh-toned. These differences in shape, texture, and colour are key when deciding if you are looking at a skin tag or a mole.
Moles form due to the clustering of melanocytes. Genetics, sun exposure, and hormonal changes all play a role. Individuals with lighter skin tones or a family history of melanoma often have more moles. They may also darken or become more prominent during pregnancy or adolescence when hormones fluctuate.
Skin tags, by contrast, are linked to friction and are more common in people who have a family history, are overweight or have diabetes. They tend to appear later in life and may increase with age. Hormonal shifts, such as during pregnancy, can also encourage their development. Unlike moles, skin tags are not tied to pigment and do not carry a risk of cancer.
Because moles can sometimes develop into melanoma, they need careful monitoring. Dermatologists often refer to the ABCDE rule for warning signs: Asymmetry, Border irregularity, Colour changes, Diameter larger than six millimetres, and Evolution over time. Any mole showing one or more of these features should be examined by a specialist.
Other symptoms that require attention include itching, bleeding, or sudden growth. Early detection of melanoma is critical, as treatment is most effective when the condition is identified quickly. For this reason, patients are encouraged to schedule routine skin checks with a dermatologist, especially if they have many moles or a family history of skin cancer.
Skin tags do not carry the same risks as moles. They are benign and not linked to skin cancer. The main concerns are irritation, discomfort, or cosmetic visibility. For example, a tag on the neck may rub against a necklace, while one under the arm may catch during shaving. Sometimes, in larger skin tags, the skin tag may twist on it’s stalk leading to a compromise in it’s blood supply. This causes pain and the skin tag to often turn dark and “bruised”.
Occasionally, the sudden development of multiple skin tags can signal underlying health conditions such as insulin resistance. In such cases, a dermatologist may suggest further medical evaluation by performing certain blood tests. While the tags themselves are harmless, they can serve as markers of overall health, and professional advice is helpful.
Treatment depends on whether the mole is benign or suspicious. If it is harmless, patients may choose to leave it alone or have it removed for cosmetic reasons. Removal techniques include surgical excision or shave removal, both of which are carried out under local anaesthetic.
When a mole is suspicious, complete removal is necessary for both diagnosis and safety. The sample is sent for laboratory analysis to confirm whether it is cancerous. At Lumine Dermatology, mole removal is performed with precision to ensure safety while minimising scarring. Patients receive tailored aftercare to support healing and ongoing monitoring to maintain long-term skin health.
Skin tags are simple to remove. Common methods include snipping with sterile instruments, freezing with liquid nitrogen, or cauterising with heat. These procedures are quick, safe, and usually carried out in a clinic setting without the need for stitches.
At Lumine Dermatology, removal is performed with attention to cosmetic outcomes. This is particularly important for skin tags on the face, neck, or eyelids, where even small marks can affect confidence. Because they are benign, skin tags do not need laboratory testing unless they look unusual.
If you are uncertain whether a growth is a skin tag or mole, a dermatologist can provide clarity. Professional evaluation ensures that no suspicious mole is overlooked. Self-diagnosis is often unreliable and can delay important treatment if changes are missed.
It is advisable to seek medical attention if a mole shows any signs of change, causes discomfort, or looks different from your other moles. Skin tags that grow quickly, change colour, or bleed should also be assessed, even though most are harmless. At Lumine Dermatology, patients receive not only expert diagnosis but also personalised guidance for treatment and follow-up.
Skin growths are not only a physical concern but also an emotional one. A visible mole or skin tag can affect self-esteem, especially when located on the face or other noticeable areas. Patients often describe feeling self-conscious or anxious about how others perceive them.
Addressing these concerns with a dermatologist provides more than medical reassurance. It helps restore confidence and comfort. At Lumine Dermatology, care extends beyond treatment to include education and emotional support, ensuring patients feel informed and at ease with their choices.

Skin tags and moles may seem alike at first glance, but they differ in origin, appearance, and risk. Moles arise from pigment cells and can sometimes develop into skin cancer, making them important to monitor. Skin tags are harmless growths that occur due to friction. They can be removed if they cause irritation or affect confidence.
When in doubt, seeking professional evaluation is the best choice. At Lumine Dermatology, patients receive accurate diagnosis, safe treatment, and compassionate care. With expert guidance, you can protect your skin, reduce worry, and feel more confident in your appearance.
