The Mayo Clinic reports that skin tags become more common as you age. A tag is a benign tumor composed of core fibers, ducts and various cell types covered by skin. It is unclear why they develop or the correlation a skin tag has with the aging process. While a skin tag is relatively harmless, it can become uncomfortable under clothing or during everyday activities. There are many home remedies that claim to remove skin tags. Among these is the application of clear nail polish. This treatment may not remove skin tags for you. It has no scientific backing, but is inexpensive and straightforward.
Wash the area with a mild soap and warm water. Pat dry the clean area with a towel. The skin tag must be dry before you apply the polish.
Dab the clear nail polish onto the skin tag, coating the tag thoroughly. Allow the polish to dry on the skin before touching it against clothing or rubbing it.
Repeat the process twice a day. According to Home Remedy Haven, this will cause the tag to shrink in size and eventually disappear.
