If the skin tag is very small, the first thing Geraghty does is spray the bump with cold liquid nitrogen, a non-toxic substance. It's sprayed out of a can and is approximately -320 degrees Fahrenheit. “We direct this very cold spray of gas onto the spot for a few seconds, then we take a break and then we do a few seconds more and usually that’s enough to make the skin tag fall off within a few days,” said Geraghty.
While definitely the smelliest choice on this list, crushed garlic has been used for generations to treat warts and skin tags. Simply crush a large clove of garlic with a knife to release the potent oils of the garlic, and then secure with a bandage over the skin tag. Best results will come with repeated overnight applications; in the morning, wash and dry the area well.
Certain endocrine syndromes, metabolic syndrome, and hormonal imbalances. Researchers have found that certain hormone-related syndromes, including polycystic ovarian syndrome and metabolic syndrome, may be related to skin tags. In fact, a small study of 110 patients with skin tags found 70 had diabetes. Additionally, researchers noted that patients with skin tags also had higher blood pressure. (4)
The punch biopsy has been done, and now the area has the mole in the middle but not yet removed. It will be taken out with forceps (a tweezer-like instrument) and put in a specimen bottle to be sent to the lab for analysis. It is important that every mole be sent for analysis in order to make sure that no atypical cells remain or that it isn't a precancerous type of mole.

A biopsy usually involves taking cells or samples from the mole to be analyzed in a lab, according to the Mayo Clinic. Moles are usually just clusters of pigment cells called melanocytes, according to the Cleveland Clinic, but sometimes they can become cancerous. A biopsy helps determine if there is anything wrong with the mole, like melanoma, the deadliest form of skin cancer.
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.
Cindy Crawford has a mole, and Marilyn Monroe had one. In the Renaissance era, they were thought of as beauty enhancers, but if a mole is unsightly or bothersome, it is worth having it removed. Madonna had a mole and didn’t like the way it looked, so she had it removed. Benign moles can be removed easily with minimal risk of scarring thanks to modern techniques.
Dermatologists say nay: The tags are almost never cancerous and don’t need to be removed; in fact, they’re (almost!) always benign. And while many people opt to remove them due to discomfort or for cosmetic reasons, there is no harm in leaving them be. There are extremely rare exceptions to this rule: In one study, two patients with known basal cell nevus syndrome (BCNS) were found to have multiple basal cell carcinomas that resembled ordinary skin tags. “There are rare cases where skin cancers, such as basal cell carcinoma, squamous cell carcinoma, and even melanoma, can mimic a skin tag,” says dermatologist Avnee Shah, MD. “Going to a board-certified dermatologist assures a trained eye is examining the lesion and determining the risk of a more harmful condition masquerading as a skin tag.” To be safe, if any tag is growing, changing color, or bleeding and itching, it’s definitely time to see an expert.

Treat with apple cider vinegar. Get a cotton ball and soak it in apple cider vinegar until it is totally saturated. Place the cotton ball on your skin tag and hold for a few minutes. You can move the ball in a circular motion on the skin to increase absorption if you like. Repeat this process three times per day until your skin tag falls off. This method is usually quite effective. Depending on your skin the vinegar may not be as effective so you can try using apple cider by itself. 
"If the skin tags are a little bigger or they have more of a thicker stalk at the bottom, then I like to just do a miniature injection of lidocaine to numb the skin and just snip them right off with some very sharp sterile scissors. It only takes a second to do," says Geraghty. "Even with that method I usually do a little bit of cautery after to burn the base because these skin tags have their own blood vessel supply. Burning the base also puts a little scab on it."
I went on my way after my doctor’s appointment, relieved. But maybe I shouldn’t have been. Many doctors I've spoken to say people with obesity are more likely to get skin tags due to the increase in skin friction. I probably weighed 120 pounds (lbs) booted out in snow gear. But there are other risk factors for skin tags — factors that, if you’re suffering from them, may be worth investigating.
