If you had stitches, your doctor will recommend that for a few days you keep the area as dry as possible and avoid doing any heavy exercise, Dr. Conrad says. (Both of these factors can throw a wrench into things if you’re super active—be sure to discuss that with your doctor if it worries you.) If you had a pretty quick and easy removal, you should be fine to return to any usual habits like working out the next day, but it’s still smart to run that by your doctor first.
Dr Yip notes that while it’s uncommon to experience an infected skin tag, it’s likely they may become red, inflamed and itchy if they're constantly rubbing against clothing and jewellery. “If there is infection, it is usually red, swollen and painful and may have pus discharge and a malodour [an unpleasant odour].” If this occurs, apply an antiseptic cream to mild irritations or see a dermatologist if the pain is more severe.
A biopsy usually involves taking cells or samples from the mole to be analyzed in a lab, according to the Mayo Clinic. Moles are usually just clusters of pigment cells called melanocytes, according to the Cleveland Clinic, but sometimes they can become cancerous. A biopsy helps determine if there is anything wrong with the mole, like melanoma, the deadliest form of skin cancer.
Make a dermatologist appointment. The majority of skin tags are harmless, but it is best to talk with a dermatologist if you notice that the tag is darker than your skin color, large in size, or unusual in shape. If you remove the tag without consulting a professional you could lose valuable time in the event that it is a sign of a larger problem.
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.
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.
