Radiofrequency Ablation

We dermatologists use radiofrequency ablation (RFA) primarily for the treatment of skin lesions, cosmetic skin tightening, and scar management. The procedure utilizes radio frequency energy from electric current , to generate heat, which targets and destroys specific skin tissues thereby, promoting healing and regeneration.

Uses of Radiofrequency Ablation in Dermatology:

Skin Lesions and Tumors: RFA is used to treat benign and some malignant skin lesions, such as warts, skin tags, DPNs, freckles, moles, sebaceous hyperplasia, and certain skin cancers like basal cell carcinoma. The heat destroys abnormal tissue with precision while minimizing damage to the surrounding healthy skin. However it is a skilled procedure that needs good energy and depth control.
Skin Tightening and Wrinkle Reduction: Non-ablative radiofrequency treatments are popular for skin tightening. They work on collagen production and enhance the skin elasticity. This method is used for facial rejuvenation, reducing fine lines and wrinkles, and to tighten mild to moderate sagging skin.
Scar Management: RFA improves the appearance of acne scars and surgical scars by resurfacing the skin and promoting collagen remodeling. Fractional radiofrequency devices are often used for this purpose, called MNRF devices. We at Subodha, have one of the world’s finest MNRF devices,( US FDA approved )for management of acne scars and various other scars. It is excellent in improving stretch marks and post pregnancy skin laxity.
Removal of Vascular Lesions: Small vascular lesions, such as spider veins or cherry angiomas, can be treated with RFA by sealing off the blood vessels, causing them to shrink and fade.

Procedure:

Preparation: Firstly, the treatment area will be properly cleaned, followed by a local anesthetic application to minimize discomfort. Typically topical anesthetic cream takes 40 minutes to create numbness.

How is it done?

A handheld RFA device delivers radiofrequency energy through electrodes or needles to the target tissue, generating heat that disrupts the lesion or stimulates collagen production.
Duration: Treatment typically lasts 15-45 minutes, depending on the area and the nature of the condition.

Benefits:

Minimally Invasive procedure: No need for incisions or extensive surgery.
Precise: It targets only the affected areas, preserving healthy tissue.
Quick Recovery: Minimal downtime, with almost all patients resuming normal activities quickly.
Cosmetic Benefits: Quite effective for tightening skin and enhancing the skin texture with better and long-lasting results.

Risks and Side Effects:

Mild swelling, redness or bruising at the treated site.
Temporary pain or discomfort while doing the procedure.
Pigmentation changes or scarring are rare.

Aftercare:

Keep the treated area clean and avoid excessive direct sun exposure.
Use gentle skincare products like cleansers and moisturizers- as recommended by the dermatologist.
Follow specific post-treatment instructions to optimize healing and results.

In conclusion, RFA is a versatile and effective option for managing various skin concerns with minimal risks and downtime. It’s best performed by a dermatologist or trained skincare professional with experience in radiofrequency techniques.
