My skin tags, of course — like the skin tags of millions of people — were fine. They didn’t irritate or bother me, though some doctors mentioned them getting twisted in necklace or irritated by rubbing on clothing. When that happens, or for cosmetic reasons, skin tags are easily removed. “There are several methods of removal — clip them with sharp scissors; freeze them with liquid nitrogen; or burn them off with heat,” meaning cauterize them, Dr. Besser says. (All of this should be performed by a medical professional, not at home.)
According to Live Science, a skin tag is basically just a skin growth that can be smooth or irregular. It may attach to the skin by a stalk. But Katy Burris, MD, an assistant professor of dermatology at Columbia University and board-certified dermatologist practicing at Columbia University Medical Center in New York City, puts it simply: “A skin tag is a soft growth of normal skin that appears like a small tag. They tend to appear in areas of high friction, where skin may rub clothing or other skin.”

Skin tags are thought to be caused by collagen and blood vessels that bunch together and get caught inside thicker skin. As skin tags more commonly occur in skin creases or fold, it is believed they are mainly caused by skin rubbing against skin. However, no one knows for sure. Skin tags affect all people of any gender. However, some people are at a higher risk for developing skin tags. You may be more likely to develop skin tags if any of the following applies to you:
After-care is vital to achieve excellent outcomes. Dr. Lam does not charge extra for this care but believes it is important for you to return several times throughout the year to ensure proper healing. It may be only 1 to 2 times but typically 4 to 6 times over a year about every 1 to 2 months depending on how the wound heals. Dr. Lam uses KTP laser (no downtime) to manage any raised or red scars and injectable scar dissolvers also as needed. He may also further refine the incision with dermabrasion or micro silicone injections to ultimately finesse the result, again only as needed and without charge.
Hormone elevations, such as those seen during pregnancy, may cause an increase in the formation of skin tags, as skin tags are more frequent in pregnant women. Tags are essentially harmless and do not have to be treated unless they are bothersome. Skin tags that are bothersome may be easily removed during or after pregnancy, typically by a dermatologist.
Not sure if your skin lesion is actually a wart? Dr Yip explains how to tell the two apart: “A skin tag is usually soft and hangs off the skin with a narrow base. Warts are rough, scaly and raised bumps on the skin surface caused by viruses, therefore they can spread easily to other body areas and may be contagious to others.” If you can’t figure out which one has taken up residence on your body, it’s best to see your GP or dermatologist. Moles can also look similar to skin tags, so when in doubt (as some moles can be cancerous), it’s always best to get them checked by a skin professional. 
Some essential oils are quite useful in treating skin issues, including skin tags. Well known for its antiseptic and antibacterial properties, tea tree oil is particularly beneficial for skin issues including skin tags. Tea tree oil comes from the Southeast Australian coast. The oil has many health and beauty benefits including skin benefits, treating fungal infections, and clearing coughs and congestion. (4)

Cutting the skin tag off. Most doctors prefer to remove a skin tag by cutting it off quickly in office. The procedure will begin with cleaning the area with an antiseptic solution. Depending on the size and location of the skin tag, the doctor may rub a numbing solution on your skin. Then, the doctor will use a very sharp tool to simply slice the tag away. The area will be cleaned again and a bandage will be applied. You can expect to feel very little pain during the procedure. Most only feel a pinprick sensation. Occasionally. tag removal may require the doctor to stitch the resulting wound.  (5)
Skin tags are small, usually measured in millimeters, but can grow to a half-inch in length. A skin tag may start to develop without you’re even noticing. Once formed, they typically don’t get any bigger. They can show up virtually anywhere on the body, but are most often on the eyelids, the neck, the groin area, and in the armpits — basically on areas of the body with folds. You may have just one or two or many, and they might be in isolated spots or in a group with many skin tags.

Insulin resistance, which may lead to type 2 diabetes and prediabetes, may also play a role in the development of skin tags. People with insulin resistance don’t absorb glucose effectively from the bloodstream. According to a 2010 study, the presence of multiple skin tags was associated with insulin resistance, a high body mass index, and high triglycerides.
