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.
Because of this, it is vital that you mix it with a carrier oil, like coconut oil or almond oil, before applying to the skin. Mix 2 drops of a carrier oil with 4 drops of a high-quality oil of oregano and apply three times a day to skin tags. You do not need to cover it with a bandage; allow it to soak into the skin naturally. Do not apply it to broken or irritated skin.
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. 
The best method for mole removal depends on different characteristics of the mole including size, shape, and color. With most moles (pigmented areas) we are either born with them, or they appear over time as we exose our skin to the sun. For flat moles, skin tags, or protruding moles that have been relatively stable since birth (with no rapid growing, shape changing, etc.) treatment with laser or excision can remove them easily. Other moles that have changed in color or contour should be removed for biopsy to determine if they are associated with skin cancer.
Use tea tree oil. Tea tree oil may be helpful for certain skin conditions, such as acne, fungal infections, and bug bites, so you can try it on your mole if you like. Brush tea tree oil on the mole twice daily using a q-tip. At night, you can also soak a cotton ball in tea tree oil and secure it over the mole with a Band-Aid. Repeat this method for a month, or however long it takes the mole to go away. However, keep in mind that applying tea tree oil to your skin daily may cause it to burn. Stop if skin irritation occurs.
