Subcision Before and After: What to Expect

Subcision uses a small needle or blade beneath the skin to loosen fibrous strands pulling an indented scar downward. A clinician first examines the depth, edges, and movement of the scar and may photograph the area for comparison. The procedure commonly involves local anaesthetic, so you can feel pressure or movement even when sharp sensation is reduced.

Immediately afterward, small entry points, tenderness, swelling, bruising, or a temporary uneven appearance can occur. The early view is not the final result: inflammation and healing can make the treated area look different from day to day. Improvement is usually judged after the skin has had time to settle, and some scars need more than one approach or session.

Tell the clinician about medicines and supplements that affect bleeding, a history of raised scars, active acne, cold sores, allergies, and previous procedures in the same area. Follow the clinic’s instructions about cleansing, shaving, makeup, and whether to pause any product; do not stop a prescribed medicine without medical advice.

After treatment, keep the area clean and follow the dressing instructions. Avoid rubbing, picking, strenuous activity, heat exposure, and unapproved active products until your clinician says they are suitable. Use gentle skincare and sun protection once the skin allows it. Keep review appointments so the clinician can assess scar release and plan any complementary treatment, such as [Acne Scar Laser Treatment](/treatments/laser-and-energy/acne-scar-laser-treatment/).

Contact the treating clinic promptly if pain, redness, warmth, swelling, or drainage is increasing rather than easing, or if the wound opens. Seek urgent medical help for heavy bleeding, rapidly spreading swelling, breathing difficulty, faintness, or a severe allergic reaction. New marked colour change, worsening numbness, or fever also deserves prompt assessment.

Ask which scars are being treated, what change is realistic for their depth, how many appointments may be considered, and which aftercare products are appropriate. Clarify when you may exercise, wear makeup, return to work, and restart prescription or cosmetic skincare. Ask how photographs will be compared and who to contact if bruising, pain, or swelling concerns you.
