Susan Besser, MD, a family medicine specialist with Mercy Medical Center in Baltimore, says that if skin tags “get large, change color, or become infected or ulcerated, you need to see your doctor. In those cases, it may not be a simple skin tag and further evaluation is needed.” By and large, Todd Minars, MD, of MINARS Dermatology in Hollywood, Florida, states, “Skin tags are harmless. If they do not bother you, then there is no need to treat them.”
Your skin is the heaviest organ in the body and takes up about 16 percent of your total weight.1 It serves many purposes, such as protecting your internal organs from microbes and environmental heat, as well as regulating body temperature.2 But due to its size and breadth, there's a chance that growths can unexpectedly form. One common example found among adults is skin tags.
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. 
Don’t impulsively deem any protruding bump as a skin tag; after all, there is an overwhelming number of things it could be—moles and seborrheic keratoses can closely resemble skin tags. Even worse, it could be something that requires medical treatment such as genital warts (possible indication of a sexually transmitted disease). Some growths could also be an extension of glands on the skin, and they can get infected if you’re poking at them at home. As a rule of thumb, if the tag is pigmented, see a dermatologist to get it evaluated. And here are 11 other skin mysteries you should know about.
I never knew what skin tags were until about 10 years ago. They’re annoying more than anything, but I know some people who are very concerned when they have them (even if they’ve gone to the doctor and been cleared). Good to see there are a number of home remedies. Not surprised to see apple cider vinegar listed as a possible solution. If ever nature produced a universal elixir, that would be it.
While the majority of skin tags are simply destroyed, sometimes tissue is sent for microscopic exam by a health care specialist known as a pathologist, who will determine the exact diagnosis and determine whether an abnormality such as skin cancer is present. Irregular skin growths that are larger, bleed, or have an unusual presentation may require pathology examination to make sure there are no irregular cells or skin cancers.
I've applied the oil at least 3 dimes daily for the past 2 weeks, but there has been no change in the size of the 5mm mole below my left lower lip nor the 2mm size mole on my right nostril. I have noticed skin peeling from the surface of the moles on a few occasions when I wash my face. And, maybe a slight color change. I plan to keep applying it and see what happens. I'm hoping for the best! * - Emma
Insulin resistance, which may lead to type 2 diabetes and prediabetes, may also play a role in the development of skin tags. People with insulin resistance don’t absorb glucose effectively from the bloodstream. According to a 2010 study, the presence of multiple skin tags was associated with insulin resistance, a high body mass index, and high triglycerides.
