Radio cautery, also known as radiofrequency (RF) ablation, uses high-frequency radio waves to cut and coagulate tissue. It is a precise, minimally invasive tool used across dermatology and surgery — and a popular choice for removing warts, skin tags and benign skin growths.

How Radio Cautery Works

A radiofrequency generator delivers high-frequency current to a fine electrode tip. When the tip contacts the skin, the radio waves make water molecules in the tissue vibrate and generate heat. That heat is used to cut tissue, coagulate (seal) blood vessels or vaporise unwanted growths with pinpoint control.

Key Advantages

• Precise: Targets tissue accurately while sparing surrounding healthy skin.
• Minimal bleeding: Heat seals blood vessels as it cuts.
• Faster healing: Less collateral damage means quicker recovery and less scarring.
• Versatile: Treats many growth types in a quick, outpatient visit.

What It Treats

• Warts: Effective for common, plantar and other warts. The area is numbed with local anaesthetic, treated with the electrode, then gently removed.
• Skin tags: A precise option for larger or bothersome tags, with minimal bleeding and quick healing.
• Benign growths: Suitable for fibromas, granuloma pyogenicum and some seborrheic keratoses. It is not ideal for lipomas or cysts.

What to Consider

• It is more expensive than some at-home removal methods and requires a clinic visit.
• Suitability depends on the type, size and location of the growth, plus your skin type and medical history.
• It may not be appropriate for everyone, including during pregnancy.

Aftercare

Some scabbing or redness in the treated area is normal and usually settles within a few weeks. Keep the area clean and dry to prevent infection, support healing with a gentle moisturiser, and protect new skin with daily sunscreen.
