Radiofrequency Cautery Treatment
Radiofrequency cautery (RF cauterization) is a modern dermatological procedure that removes unwanted skin growths using high-frequency radio waves.
It is safe, effective, and minimally invasive, making it a preferred choice for patients seeking precise removal of skin lesions with minimal downtime and excellent cosmetic results.
What is Radiofrequency Cautery?
Radiofrequency cautery works by delivering high-frequency alternating current (0.5–4 MHz) through a fine electrode tip.
When the electrode touches the skin, the energy generates controlled heat within the tissue, allowing the dermatologist to cut, coagulate, or vaporize the targeted lesion without damaging surrounding healthy skin.
Because the heat is generated directly inside the tissue, RF cautery provides:
• High precision
• Minimal bleeding
• Faster healing
• Low risk of scarring
Skin Conditions Treated with RF Cautery
RF cautery is effective for the safe and quick removal of:
• Skin tags
• Moles (non-cancerous)
• Warts (including plantar and periungual)
• Seborrheic keratosis
• Syringomas
• Xanthelasma (yellow patches on eyelids)
• Cherry angiomas (red spots)
• Dermatosis Papulosa Nigra (DPN)
• Small cysts
Step-by-Step Procedure:
1. Consultation & Skin Assessment
The dermatologist examines the lesion to confirm it is benign and suitable for RF removal.
2. Cleansing & Anesthesia
The treatment area is cleaned with an antiseptic solution, and local anesthesia (cream or injection) is given to ensure comfort.
3. Precise Lesion Removal
Using a fine RF probe, the lesion is removed or coagulated with controlled radiofrequency energy.
4. Post-Procedure Care
An antibiotic ointment is applied, and you will be given aftercare instructions to ensure smooth healing.
Advantages of Radiofrequency Cautery
Post-Treatment Care Tips
• Keep the treated area clean and dry for the first 24 hours
• Apply prescribed ointment as directed
• Avoid scratching, rubbing, or applying makeup until healed
• Use a broad-spectrum sunscreen daily to protect from UV damage
• Avoid swimming pools and saunas for a few days
Possible Side Effects
While RF cautery is considered very safe, some temporary side effects may occur:
• Mild redness or swelling
• Small scab formation
• Temporary pigmentation changes
• Rare chance of infection if aftercare is not followed
These effects usually resolve naturally within a few days to weeks.
FAQ's

If you have skin tags, moles, warts, or other benign lesions, consult a qualified dermatologist for a professional RF cautery treatment.
FAQ's
With local anesthesia, most people feel only a gentle warmth or a light prick during the procedure. Any discomfort is mild, brief, and usually over within seconds.
Yes, when done by an experienced dermatologist, RF cautery is safe for all skin types, including sensitive and darker skin.
Most patients resume daily activities immediately after treatment.
Most procedures take 10–30 minutes, depending on the size and number of lesions.
Once removed, the same lesion generally does not recur, but new lesions may develop due to genetics or other factors.
