A mole is a skin abnormality that develops when skin grows in a cluster instead of spreading out. These are usually dark, small patches of skin no larger than the size of an eraser head. Although they are most often harmless, some moles can develop into melanoma skin cancer. If you are concerned about a mole that may be cancerous, please refer to our skin cancer treatment page.
While it is true that skin tags often show up in the armpit or neck creases, the skin-on-skin friction is not what’s to blame. Rather, it’s the creases and skin folds that produce a friendly environment for a virus that may cause some skin tags. According to Ben Johnson, MD, founder of holistic beauty brand Osmosis Skincare, “Viruses are much more commonly spread through contact than people realize, but they don’t find the skin an easy place to survive. Creases improve their chances, and on rare occasions, one makes it into the follicle and infects local skin DNA to create skin tags.”
Those who are concerned about scarring should consider seeking out a plastic surgeon as they understand the cosmetic approach to take. This is recommended especially to those who have larger moles. A plastic surgeon will focus on minimizing scarring as much as possible. Post-surgery care is especially important to create a natural, attractive outcome.
Don’t impulsively deem any protruding bump as a skin tag; after all, there is an overwhelming number of things it could be—moles and seborrheic keratoses can closely resemble skin tags. Even worse, it could be something that requires medical treatment such as genital warts (possible indication of a sexually transmitted disease). Some growths could also be an extension of glands on the skin, and they can get infected if you’re poking at them at home. As a rule of thumb, if the tag is pigmented, see a dermatologist to get it evaluated. And here are 11 other skin mysteries you should know about.
Recognize the benefits of professional medical care. It is very tempting to treat skin tags at home, but your doctor’s care offers some unique benefits. They will use sterile instruments to prevent infection. They will also rub on numbing cream to reduce your pain during and after the procedure. In addition, some of the methods, such as cauterization, are so advanced that they rarely leave a noticeable scar.[7]
While the majority of skin tags are simply destroyed, sometimes tissue is sent for microscopic exam by a health care specialist known as a pathologist, who will determine the exact diagnosis and determine whether an abnormality such as skin cancer is present. Irregular skin growths that are larger, bleed, or have an unusual presentation may require pathology examination to make sure there are no irregular cells or skin cancers.
Like moles, removal of skin tags poses a threat of exacerbation of the tumorous site. Though rare, it is possible to develop a malignant tumor by removal. If removal is desired or warranted, it can be achieved using a home treatment kit eg Skin Tag Zap™, dermatologist, general practitioner or similarly trained professional who may use cauterisation, cryosurgery, excision, laser,[10] or surgical ligation to remove the acrochorda.[2]

Most people choose to remove them for cosmetic reasons, especially skin tags that surface on the neck, eyelid, or face. In rare cases, a skin tag can get irritated and infected. In that case, skin tag removal is the best course of action to prevent infection from reoccurring. But, what causes them? And once you have them, you need to know how to get rid of skin tags. We’ll explain it all.

These small (often) flesh-colored benign growths can develop anywhere on the face or body. And both men and women (of all ethnicities) are vulnerable to the condition. You may not even be aware that you have skin tags. The problems begin when they’re easy to see, form in a cluster or they grow in size. They can also become irritated, infected or blood-filled.

More than half if not all of the general population has been reported to have skin tags at some time in their lives. Although tags are generally acquired (not present at birth) and may occur in anyone, more often they arise in adulthood. They are much more common in middle age, and they tend to increase in prevalence up to age 60. Children and toddlers may also develop skin tags, particularly in the underarm and neck areas. Skin tags are more common in overweight people.

Experts don't know the exact cause of skin tags, but they believe that these growths appear when skin rubs against skin. As such, skin tags are often found in armpits, or on the neck and groin.9 In other cases, your skin tag may be confused with a condition known as the Birt-Hogg-Dube (BHD) syndrome, a condition that produces growths on the skin that look exactly like  skin tags.10

Repetitive friction and wearing tight clothes may contribute to skin tags in people who are overweight. According to a medical paper written by dermatologists in Spain, an obese patient, whose job required repeating lifting of her arms, developed a pattern of skin tags along her bra straps from the constant friction. Avoiding tight clothing if you are overweight is suggested.
Lemon juice is a powerful antiseptic, and it also contains citric acid which helps to dry out skin tags by decomposing the cells. Take a half of fresh lemon and apply the juice to a cotton ball. Apply this directly to the skin tag and leave it on without washing it off. You can apply this up to three times a day and continue the routine until the skin tag falls off.
Apply tea tree oil. This oil is well known for its anti-fungal properties. Get out a clean cotton ball. Dip it into clean water and then place three drops of tea tree oil onto the ball. Wash the area of the skin tag and the skin 1” around it using the cotton ball. Repeat three times a day. This is an effective way to dry up your tag as long as you are consistent with oil applications.[11]
Moles, medically known as nevi (nevus, in singular), are benign conditions of the skin that can be raised or flat, pigmented or flesh colored. Mole removals should only be undertaken after considerable deliberation and thought. Since they oftentimes occur in highly conspicuous areas like the central face, the recovery following a mole removal may be several months before they are not immediately obvious to an observer that you had surgery. Mole removal techniques are graduated and adjusted depending on the type of mole, location of mole, and how unsightly it is aesthetically. Dr. Lam believes that excellent mole removal is predicated not only on superior surgery but also on meticulous and frequent follow-up care to ensure the incision heals well.
The Staff was AWESOME!!!!! I finally found a business that knows what it takes to keep customers happy. On my first visit the staff had every thing set up and ready to go. The paper work was very easy to fill out and my wait time was less then 10 min now that alone is 5 stars compared to other places that made me wait over a hour. They gave me great service and helped with every problem I requested. Florida Skin Center is #1 in my book a customer for life.
And I was getting them exactly where I was expected to. Michele Farber, MD, of Schweiger Dermatology Group in New York City, says they can happen anywhere, but “they are normally on the neck, underarms, [and] underneath the breasts and the groin folds.” Cynthia Abbott, MD, who works with Dermatology Affiliates in Marietta, Georgia, says that while “skin tags are an outgrowth of skin most commonly occurring due to constant rubbing and irritation,” that they “can form anywhere, but the waistline, underarms, groin, neck, and other areas of friction with necklaces and clothes are the most common locations.”
