Skin Tag Removal by Cauterization: What You Need to Know
Skin tags—those small, soft growths that often appear on the neck, armpits, eyelids, or other areas of friction—are completely harmless but can be annoying or unsightly. While there are several ways to remove them, cauterization is one of the most effective methods for permanent removal.
But how does it work, is it painful, and what should you expect during the procedure? Let’s take a closer look.
What is Cauterization for Skin Tag Removal?
Cauterization is a medical procedure that uses heat to burn off the skin tag. This is typically done with a cautery pen or an electrocautery device, which delivers a small electrical current to remove the skin tag while sealing the wound to prevent bleeding.
This method is quick, minimally invasive, and prevents regrowth in most cases.
How Does the Procedure Work?
1. Cleansing & Numbing – The area is disinfected, and a local anesthetic may be applied to reduce discomfort.
2. Burning the Skin Tag – A heated cautery tool is used to burn away the skin tag at its base.
3. Sealing the Skin – The heat also seals blood vessels, reducing bleeding and lowering the risk of infection.
4. Healing & Aftercare – A scab forms over the treated area, which falls off naturally within a few days to a couple of weeks.
The whole process usually takes only a few minutes.
Is Cauterization Painful?
Most people feel a mild burning sensation or warmth, but numbing cream or local anesthesia helps reduce discomfort. After the procedure, there might be some tenderness or redness, but it’s usually mild.
What Are the Benefits of Cauterizing Skin Tags?
Quick Procedure – Usually takes just a few minutes per skin tag.
Minimal Bleeding – Since the heat seals blood vessels, there’s little to no bleeding.
Low Risk of Infection – Cauterization destroys bacteria, lowering infection risks.
Prevents Regrowth – Unlike some removal methods, cauterization typically prevents skin tags from coming back in the same spot.
Possible Side Effects and Risks
Mild discomfort or burning sensation after the procedure.
Temporary redness or slight scarring, especially on sensitive skin.
Skin discoloration (rare, but more common in darker skin tones).
Infection (very rare) if aftercare instructions aren’t followed properly.
Aftercare Tips for Faster Healing
Keep the area clean and dry to prevent infection.
Avoid picking at the scab—let it fall off naturally.
Apply an antibacterial ointment if recommended by your doctor.
Avoid sun exposure on the treated area to prevent hyperpigmentation.
Most people heal within one to two weeks with minimal scarring.
Is Cauterization the Best Method for Skin Tag Removal?
Cauterization is one of the best methods for permanent removal, but alternatives like cryotherapy (freezing), cutting, or laser removal are also available. If you’re unsure which option is best for you, consult a dermatologist to determine the most suitable method for your skin type and location of the skin tag.
