Skin tags are generally not a cause of concern as they're extremely common and are noncancerous. You'll mostly find them where your skin has folds such as eyelids, armpits etc. While in most cases skin tags are painless, but in some cases they can end up becoming painful due to constant friction. Most people want to get rid of skin tags due to cosmetic reasons only and they want to try a home remedy such as apple cider vinegar due to its proven effectiveness in other skin conditions and countless health benefits.
Apple cider vinegar contains acetic acid and the acidic properties that it has can be helpful in breaking down the skin tissue that surrounds the skin tag. This eventually causes the skin tag to fall off. Although many people use apple cider vinegar for various purposes but there's not much scientific evidence that shows that it can remove skin tags. However there are some studies that show that apple cider vinegar may cause chemical burn. Basically, you may get rid of the skin tag but you may end up with scarring and hyperpigmentation which in reality will be way harder to take care of than skin tags.
Using apple cider vinegar to treat skin tags may not be worth it because the benefits don't actually outweigh the risks. While getting rid of the skin tag may entice you to use it but being left with a chemical burn and scarring is not a good idea either.
