A 4 MHz current that cuts tissue and seals small blood vessels in a single step.
4 MHz radiofrequency cuts the lesion and simultaneously coagulates small vessels. Clean removal with very little bleeding vs scalpel.
Multiple modes (pure cut, blend, coagulation) adaptable. Loop or fine needle chosen based on the lesion. Surrounding healthy tissue preserved.
4 MHz frequency limits lateral thermal injury vs traditional electrocautery. Clean healing and scar generally discreet.
Six types of benign raised lesions the physician can remove in clinic after confirming they are benign.
Skin growths (skin tags) on the eyelids that become bothersome or inflamed due to eyeglass friction.
Yellowish patches (xanthelasmas) on the eyelids that are not reduced by creams or dietary changes.
Thick brown or black rough patches (seborrheic keratoses) that rub against the lashes or frames of eyeglasses.
Yellowish bumps (sebaceous hyperplasia) around the eyes that increase in size and become visible.
Raised mole (dermal nevus) on the eyelid, stable and benign, that rubs against the eyelids or glasses.
Three situations where radiofrequency is not used, and three where another method is preferred.
Pacemaker, defibrillator, or other implanted electronic device — risk of electromagnetic interference from radiofrequency.
Active infection in the treatment area — including stye, skin herpes, or open wound.
Lesion that changes rapidly, bleeds, or has irregular borders — referral to dermatologist before any removal.
Dark skin (skin types IV to VI) — higher risk of post-inflammatory hyperpigmentation.
Anticoagulant medication use or known bleeding disorder — greater risk of bleeding during the procedure.
A short appointment: examination, local anesthesia, simultaneous cutting and coagulation, and home care instructions.
Lesion examination and confirmation that it is benign. Check for pacemaker absence. Anesthetic cream 30-45 min prior and local lidocaine injection.
A 4 MHz loop or fine needle that simultaneously cuts and coagulates. Actual procedure 1 to 3 min per lesion. The eyelid margin is avoided.
You can leave immediately. Scab falls off naturally within 5 to 10 days. No makeup for 7 days. Antibiotic ointment for 5 to 7 days. SPF 50+ for 8 weeks.
THE CARE EXPERIENCE
Family doctor and graduate of the Université de Montréal, in good standing with the Collège des médecins du Québec (CMQ), Dr. Karen Dzolang serves as medical director for the CARE network. For eyelid lesions and skin plaques near the eye, she helps frame the evaluation, possible indications, treatment limits and situations where another medical opinion is preferable.
