What should you know about radiofrequency subcision?

Subcision uses a needle or cannula beneath the skin to loosen strands that pull a depressed scar downward. Radiofrequency may add heat to the planned treatment area, depending on the device and protocol. This approach is most relevant to scars with a tethered, rolling depression; raised or deep narrow scars may need a different strategy.

Bruising, swelling, tenderness, and temporary unevenness can follow because tissue has been mechanically released. The final appearance changes as inflammation settles and collagen remodels, so early swelling is not the final result.

At consultation, show the clinician how the scar behaves when the surrounding skin is stretched and disclose active acne, infection, medicines that increase bleeding, cold sores, allergies, and any tendency to form raised scars. Ask whether radiofrequency is actually part of the planned procedure.

Keep treated skin clean and avoid pressure, vigorous rubbing, heat, and unapproved products while it heals. Follow dressing and medication instructions. Sun protection helps reduce the chance that inflammation leaves a darker mark. Additional scar treatment may be considered after assessment of the response.

Contact the clinic if bleeding does not settle with the instructed pressure, swelling or pain is increasing, or the area becomes hot and progressively red. Pus, fever, wound separation, blistering, or a rapidly worsening colour change requires prompt medical review. Sudden severe pain or visual symptoms after facial treatment needs urgent assessment.

Ask whether your scar is tethered, which instrument and energy will be used, what bruising and downtime to expect, and whether another treatment will be paired with subcision. Clarify wound care, pain relief, sun protection, follow-up timing, and signs of infection.
