Noticed a new bump on your skin and are wondering what it is? You’re not alone. Every week, people walk into their local aesthetic clinic in Singapore or another country, asking the same question: “Is this a mole or just a skin tag?” Both are common, and both are usually harmless — but they’re not the same. And when it comes to skin tag removal or mole checks, knowing the difference helps you make the right call. Let’s break it down in plain English.
What Is a Skin Tag?
Skin tags are small, soft growths. They usually pop up in places where your skin folds or rubs — like your neck, underarms, eyelids, groin, or under your breasts.
They’re:
- Flesh-coloured or slightly darker
- Soft to the touch
- Connected to the skin by a thin stalk
Skin tags are completely harmless. They won’t turn cancerous, and they don’t usually cause pain. But they can be annoying — especially when they snag on clothes or jewellery. Some people also don’t like how they look.
If you want them gone, there are easy in-clinic treatments available. Options include cryotherapy (freezing), cauterization (burning), or simple removal with sterile tools.
What Is a Mole?
Moles are made up of pigmented cells called melanocytes. They’re common and can appear anywhere on the body. Some people are born with them, while others develop them over time, often due to sun exposure.
You can recognize moles by a few key features:
- Usually round or oval
- Can be flat or slightly raised
- Uniform in color, usually brown, black, or tan
Typically smooth-edged
Most moles are also harmless. But unlike skin tags, some moles can become cancerous — which is why you should keep an eye on them.
So, How Can You Tell the Difference?
Skin tags and moles may seem similar, but they have distinct traits. Skin tags are usually small, soft, and flesh-coloured. They tend to appear in areas where the skin folds or rubs, like the neck, armpits, or underarms. They often dangle slightly from the skin and are connected by a thin stalk.
Moles, on the other hand, are usually more pigmented — ranging from light brown to dark brown or even black. They can be flat or raised, round or oval, and appear almost anywhere on the body. Moles tend to have a more solid structure and sit flush or slightly raised from the skin. The colour of moles is generally uniform, while skin tags usually match your natural skin tone.
When Should You See a Doctor?
While most skin tags and moles are harmless, it’s important to know when to see a doctor. If a mole changes in size, shape, or colour or starts to itch, bleed, or feel tender, it’s time to get it checked. Look out for uneven edges, multiple shades within the same spot, or sudden growth. These could be early signs of skin cancer.
Doctors often use the ABCDE method to evaluate moles — looking at asymmetry, border irregularities, colour changes, diameter, and evolution over time. Even if the change seems small, getting a professional opinion is always the safest route.
Final Thoughts
Skin tags are mostly cosmetic concerns. Moles, while often harmless, can occasionally signal something more serious. If you're unsure what you're dealing with — or just want it removed — talk to a qualified professional. A licensed aesthetic clinic can help you assess the spot, explain your options, and remove it safely if needed. Don’t second-guess your skin. When in doubt, get it checked. Your peace of mind is worth it.
