Congenital nevi are moles that are present at birth. Congenital nevi occur in about one in 100 people. These moles are slightly more likely to develop into melanoma (cancer) than are moles that appear after birth. A mole or freckle should be checked if it has a diameter of more than a pencil eraser or any characteristics of the ABCDEs of melanoma (see below).
Tie it off. You can use fishing line, dental floss, or a thin cotton string in this method. Tie the string around the base of your skin tag. Tighten the tie until it is firm, but not painful. Snip off the excess and leave the string in place. Your skin tag should fall off due to lack of circulation. This is a version of what doctors can perform in their office using sterile tools.
Use tea tree oil. Tea tree oil may be helpful for certain skin conditions, such as acne, fungal infections, and bug bites, so you can try it on your mole if you like. Brush tea tree oil on the mole twice daily using a q-tip. At night, you can also soak a cotton ball in tea tree oil and secure it over the mole with a Band-Aid. Repeat this method for a month, or however long it takes the mole to go away. However, keep in mind that applying tea tree oil to your skin daily may cause it to burn. Stop if skin irritation occurs.
