Skin tags on the neck are extremely visible, and may get caught in clothing or jewelry and become irritated, so it is natural to want to get rid of them.
Apple cider vinegar is reputed to be a very effective remedy for skin tags.
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.
It is typical to experience some itching when treating your skin with vinegar. If it gets too annoying, dilute the vinegar a bit with water before the next application.
