Subcision With Filler: What to Know Before and After

A clinician uses a needle or cannula under the skin to separate fibrous bands that pull a rolling or tethered scar downward. Filler may then be placed in the released space to provide contour support. The exact product, amount and injection depth depend on the scar pattern, skin, and treatment plan.

Before treatment, discuss active acne, cold sores, allergies, medicines that affect bleeding, and any previous filler. Arrange a review of whether subcision alone, filler, or another approach such as Acne Scar Laser Treatment fits your scars.

Follow the clinic's instructions about cleansing, makeup, exercise and medicines. Arrive with clean skin and tell the clinician about every injectable or cosmetic procedure in the area. Afterward, expect tenderness, bruising, swelling or temporary unevenness. Use only the aftercare advised for your product and avoid pressing or massaging the area unless instructed.

Keep the follow-up appointment so the clinician can assess healing and decide whether further treatment is appropriate. Improvement is usually assessed after swelling settles, not immediately after the procedure.

Contact the treating clinic promptly for worsening pain, spreading redness, increasing warmth, drainage, fever, or swelling that continues to intensify. Seek urgent care for sudden vision changes, severe unusual pain, pale or dusky skin, weakness, or trouble speaking after filler, because these symptoms need immediate assessment.

Ask which scars are tethered, why filler is being considered, which product will be used, what normal swelling should look like, how long to avoid strenuous activity, and when results should be reviewed.
