Congenital nevi are moles that are present at birth. Congenital nevi occur in about one in 100 people. These moles are slightly more likely to develop into melanoma (cancer) than are moles that appear after birth. A mole or freckle should be checked if it has a diameter of more than a pencil eraser or any characteristics of the ABCDEs of melanoma (see below).

While it is true that skin tags often show up in the armpit or neck creases, the skin-on-skin friction is not what’s to blame. Rather, it’s the creases and skin folds that produce a friendly environment for a virus that may cause some skin tags. According to Ben Johnson, MD, founder of holistic beauty brand Osmosis Skincare, “Viruses are much more commonly spread through contact than people realize, but they don’t find the skin an easy place to survive. Creases improve their chances, and on rare occasions, one makes it into the follicle and infects local skin DNA to create skin tags.”
Soak a clean cotton ball in water and then add three drops of tea tree oil or castor oil to it. Thoroughly clean the skin tag and the surrounding area with soap and water and then completely dry the area. Use the cotton swab that has water and tea tree oil on it and gently massages the skin tag and the surrounding area three times a day. It is important to use the water because tea tree oil should always be diluted or else you are at risk for skin irritation.
Cutting the skin tag off. Most doctors prefer to remove a skin tag by cutting it off quickly in office. The procedure will begin with cleaning the area with an antiseptic solution. Depending on the size and location of the skin tag, the doctor may rub a numbing solution on your skin. Then, the doctor will use a very sharp tool to simply slice the tag away. The area will be cleaned again and a bandage will be applied. You can expect to feel very little pain during the procedure. Most only feel a pinprick sensation. Occasionally. tag removal may require the doctor to stitch the resulting wound.  (5)
If you notice a growth on your skin, don't assume it's a skin tag right away. Check with a doctor first, as it can signify a more severe condition. If the growth is confirmed to be a skin tag and you want to remove it manually, sterilize your tools and check for any allergic reactions first, particularly if applying essential oils. If home remedies don't work, you may visit a dermatologist as a last resort.

There are no currently medically approved creams for the removal of skin tags. Skin tags are typically removed by physical methods like cutting off or tying off with dental floss. It is not advisable to use unapproved products like Dermasil, wart removers, tea tree oil, nail polish, toothpaste, or hair-removal creams like Neet or Nair. Trial uses of unapproved creams may cause irritation and possible secondary complications.
The causes of skin tags are not entirely clear but their presence in skin fold areas suggests that friction or frequent irritation is a potential cause. The condition appears to have a genetic component (there is a tendency for skin tags to occur in families) but other potential causes include hormonal imbalances. For example, skin tags are associated with agromegaly, the growth hormone disorder.
Doctors remove many moles every day, but there is always one recurring theme that dermatologists tell people: Be aware of your body and any moles that have changed over time. This is especially true for moles that are dark or flat. Invariably, people will see doctors and be extremely concerned about raised, lightly colored moles, but they are not concerned about the dark, black melanoma (skin cancer) next to the mole. This is truly important.

Your mole removal treatment will depend on the technique used for removal. However, it may take a few weeks to notice the full results from treatment. If your mole is being removed by excision, we will use a topical anesthetic to minimize discomfort during your treatment. You may also have some discomfort, swelling, and scarring following your treatment.
Like moles, removal of skin tags poses a threat of exacerbation of the tumorous site. Though rare, it is possible to develop a malignant tumor by removal. If removal is desired or warranted, it can be achieved using a home treatment kit eg Skin Tag Zap™, dermatologist, general practitioner or similarly trained professional who may use cauterisation, cryosurgery, excision, laser,[10] or surgical ligation to remove the acrochorda.[2]
Be aware that home remedies are not supported by medical evidence. Most home remedies are based on anecdotal evidence, meaning that some people have tried these remedies and reported that they had success. However, treating a mole at home can be unsafe and high risk. The mole may be cancerous and this requires medical treatment. Make sure to talk with your doctor about your moles before trying any home remedies.
I’ve actually used 3 of the methods mentioned, 1 was by accident! I actually tied a hair around one and after a few failed attempts I tied it so tight it almost hurt, a few days later it was gone. Also tried using wart remover but it was painful. And lastly, I accidentally scratched one off… I wouldn’t recommend this as it bleeds A LOT and it’s obviously painful. All work but I’d suggest tying thread or string!

Recognize the benefits of professional medical care. It is very tempting to treat skin tags at home, but your doctor’s care offers some unique benefits. They will use sterile instruments to prevent infection. They will also rub on numbing cream to reduce your pain during and after the procedure. In addition, some of the methods, such as cauterization, are so advanced that they rarely leave a noticeable scar.[7]
The internet, of course, is full of interesting suggestions, including tying the stalk of a skin tag with dental floss or thread in an attempt to strangulate it and make it fall off. This, too, is a recipe for traumatizing your skin. Don't fall for sites hocking skin tag removal products. The right way to remove a skin tag is at the dermatologist's office. If you've been Googling "how to remove skin tags at home," you might as well stop.
There are a few methods that can be used in removing a mole. Factors such as depth, size and location will help determine the most effective removal method. Moles that are flush to the skin may be able to be removed using a simple shaving technique or a laser treatment. For deep-seated moles, excision is the only way to remove it safely and effectively. During this process, the doctor will cut away the mole along with a small border of skin that surrounds it. Sutures are placed deep within the excision so that a clean, thin scar will be all that remains. 
During the one month using this oil, at times I had my doubts. I was using it for a new small round mole near my smile line. I had mild inflammation up to the size of a quarter surrounding the target area. That area peeled constantly, even though I was careful to keep the oil off of it. I had very minor bleeding around 2 1/2 weeks, after washing my face one time, and so the mole then had a scab appearance. Finally at one month it departed. I have a very faint, slightly brown circle at the site, with no pitting or scarring. I would use it again. I liked what I learned about this company, which is why I gave it a try. * - Sharon

Cauterization. Burning off a skin tag should never be attempted at home. This is a procedure that must be conducted by an experienced medical professional. Electrocauterization requires a special tool that is heated and then carefully applied to the skin tag; the skin tag may not come off immediately. It may fall off in the hours or days following the procedure.
And I was getting them exactly where I was expected to. Michele Farber, MD, of Schweiger Dermatology Group in New York City, says they can happen anywhere, but “they are normally on the neck, underarms, [and] underneath the breasts and the groin folds.” Cynthia Abbott, MD, who works with Dermatology Affiliates in Marietta, Georgia, says that while “skin tags are an outgrowth of skin most commonly occurring due to constant rubbing and irritation,” that they “can form anywhere, but the waistline, underarms, groin, neck, and other areas of friction with necklaces and clothes are the most common locations.”
