Introduction

Electrosurgery is a cornerstone in dermatology, offering a precise way to cut, coagulate or ablate tissue using high-frequency electrical energy. The Surtron® system provides exceptional control, enabling our consultant dermatologist to treat lesions with accuracy and reduced trauma to surrounding skin.

At Skinhorizon Clinic, we use Surtron® for safe, minor surgical procedures — whether cosmetic or medical — under CQC-regulated conditions.

How the technology works (technical detail)

The Surtron® electrosurgical unit generates high-frequency alternating current, applied via fine electrodes. Depending on the mode (cut, coagulate, blend), the current vaporises targeted cells or coagulates small vessels, ensuring precision and haemostasis.

Key benefits include:

  • Ability to cut and coagulate simultaneously — minimal bleeding.
  • Controlled thermal spread — preserving healthy tissue.
  • Adjustable power and waveform for different lesion types.
  • Use of fine tips and loops for delicate dermatological procedures.
Treatment process step-by-step
  1. Consultation & diagnosis – lesion examined via dermoscopy, malignancy ruled out before removal.
  2. Anaesthesia – local numbing injected for patient comfort.
  3. Electrosurgical removal – lesion excised, shaved, or coagulated with Surtron® device.
  4. Haemostasis – simultaneous coagulation reduces bleeding.
  5. Aftercare – antiseptic dressing, written wound-care guidance, optional histology if clinically required.

Applications of Surtron® Electrosurgery

  • Mole removal (if benign or for cosmetic reasons, pending dermatology clearance).
  • Warts and verrucae.
  • Seborrhoeic keratoses (“age spots” or “barnacles”).
  • Skin tags in friction zones.
  • Small precancerous lesions such as actinic keratoses (where clinically indicated).
  • Superficial vascular lesions and small benign growths.
Recovery & downtime

Most patients experience only mild redness or scabbing. Healing typically takes 5–14 days depending on size/site. Sun protection and simple wound care are essential for best cosmetic outcome. Makeup may be worn after healing is complete.

Safety & side effects

Risks include mild discomfort, temporary redness, swelling, scarring or pigment changes. Rare risks include infection or recurrence. All procedures are performed by trained dermatology clinicians with sterile technique. Suspicious lesions are not treated electrosurgically without histology.

Before & After Results

Patients notice immediate removal of the targeted lesion. The treated area typically heals with minimal scarring, leaving smoother, clearer skin. Where histology is requested, the sample is processed and results communicated at follow-up.

Frequently Asked Questions

Is Surtron® safe for mole removal?
Yes — if a mole is confirmed benign by dermoscopy. Suspicious moles require biopsy/histology instead.
Does it hurt?
A local anaesthetic is used. The procedure itself is painless.
Will I have a scar?
Most sites heal with minimal scarring, but outcome depends on lesion size, depth, and your skin type.
How long is recovery?
Typically 5–14 days, with scabs falling off naturally. Sun care is essential during healing.
Can Surtron® be used for cancerous lesions?
No — suspected cancerous lesions must be biopsied and managed appropriately. Surtron® is only for benign or precancerous lesions as advised by a consultant.
