Although skin tags are primarily a cosmetic problem, that doesn’t mean they’re not significant enough to consult a doctor. For starters, they can still bleed when they come off, so dermatologists stress never trying to cut or pull off a skin tag on your own. One theory on skin tag removal is that tying it off with dental floss will remove it—a bad idea, according to Tanya Kormeili, MD, “This may remove the small ones, but some of the bigger ones have a larger blood supply and may become very painful as you strangulate the skin tag. They are easily removed in the office by a dermatologist.”
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.
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.
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
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. 
As far as other DIY methods for skin tag removal at home, such as applying apple cider vinegar, coconut oil, tea tree oil, etc., Geraghty notes that there's no compelling evidence to show that those therapies are effective. "You can't make tissue disappear by putting a little vinegar on it. It just doesn’t work... You really need that to physically be removed."
