Nope: Don’t cringe away from your friends or family affected with skin tags; they pose no threat to you whatsoever. Even though some skin tags may be caused by a virus (HPV), once the virus has embedded itself, it’s not going anywhere. “Viruses land on your skin all the time and the virus itself is minimally contagious because the skin is not a great habitat on its own,” notes Dr. Johnson. “It takes a special environment to give the virus a chance to infect our skin cell DNA. Once it has survived and embedded itself, the skin keeps it isolated so that the only result is the skin tag itself.” Here are the 37 worst pieces of advice dermatologists have heard.
Skin tags themselves have a core of fibers and ducts, nerve cells, fat cells and a layer of skin surrounding it. They may have a stalk and generally look like a small piece of hanging skin. Skin tags may have a smooth surface or an irregular surface. They are often raised and either slightly brown or flesh colored. They generally start quite small and flat, like the bump on a pinhead. Sizes vary, and they can grow up to 5 cm in size. (2)
The cause of acrochordons is unknown, however there are several theories. Irritation or friction to the skin, as occurs with skin rubbing on skin in body folds, may play a role in their formation. Acrochordons are found more commonly in people who are overweight or have diabetes. This may be due to body habitus (more skin folds), but some people think insulin resistance may somehow contribute to the development of these harmless tumors. A study of 49 patients with acrochordons showed that the human papilloma virus (HPV) was present in a high percentage of growths, suggesting the virus plays a role in development. It is also possible that acrochordons are genetic or simply due to normal aging and loss of elastic tissue. There is a genetic disorder called Birt-Hogg-Dube Syndrome that is characterized by numerous skin tags along with other skin and systemic findings.
Shaving: A combination treatment that uses electrocautery and shaving to reduce the appearance of protruding moles. Mole shaving does not remove the root of the mole, so there is no excision scar, however there is a chance it will grow back over time. This procedure is most commonly used on protruding moles in areas that do not heal well with excision (nose).  
These benign growths often appear on the folds of the skin where moisture and friction are common. This includes under arms and in the armpit region, on the neck, under the breast, near the genitals, on eyelids, or on the torso. While they can be irritated by clothing or jewelry, they typically are painless. Rarely, if a skin tag is twisted, a small blood clot can develop, which may make it tender or painful.
Hormone elevations, such as those seen during pregnancy, may cause an increase in the formation of skin tags, as skin tags are more frequent in pregnant women. Tags are essentially harmless and do not have to be treated unless they are bothersome. Skin tags that are bothersome may be easily removed during or after pregnancy, typically by a dermatologist.
Skin tags, medically termed as acrochordons or fibroepithelial polyps (FEP), are just a tiny benign bit of flesh that is typically connected to the underlying skin by a thin stalk. Yeah, gross. On the exterior, they look like minuscule bits of “hanging” skin that are typically taller than wide. These growths are seen in approximately half of all people and can form for a variety of reasons. However, they turn up more often during pregnancy, in diabetics, obese individuals, and those that have a family history of skin tags. They are also more common as you age—and men and women suffer them at about the same rate.
Avoid using mole removal creams. These creams are often sold online, marketed as a cheap, noninvasive alternative to surgical removal. In fact, mole removal creams can end up leaving deep pockets in your skin, since they go beyond the mole and dig into the skin underneath, causing irreparable damage. The small scar left behind by surgical removal is minimal in comparison.[6]
Dr. Lam performs careful mole removal based on the type of mole one has. If the mole is relatively flat and not very unsightly, he may elect to cauterize it off to minimize the cost and recovery compared to a surgically incised mole removal. However, if the mole is elevated and/or unsightly, he may excise the mole to ensure that it is properly eradicated since cautery can lead to recurrence. As seen in the Figure, elevated moles have a portion that remains under the skin that will lead to recurrence if not excised, so cauterization of raised moles most oftentimes fails.
It’s not quite a mole, pretty sure it’s not a wart. What on earth are those fleshy little bumps hanging off your skin? Allow us to introduce you to your skin tags. Don’t freak out - they are completely harmless. Just more of an annoyance than anything. And while there’s no need to rush off and get them removed (we repeat, they are not a medical emergency), we get that you’d rather not have them in your life. In which case, this is what you can do - and everything else you need to know about these weird and not-so-wonderful things called skin tags.
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.
