What to expect from punch excision for acne scars

A clinician cleans and numbs the skin before using a small circular instrument to remove the scarred core. The opening is usually closed with a suture or allowed to heal according to the technique chosen. The aim is to replace a deep, sharply defined depression with a finer healing line that may be easier to blend with later scar treatment. Punch excision is usually considered for individual scars rather than broad uneven texture, and the exact approach depends on scar depth, location, skin type, and the condition of nearby skin.

Tell the clinician about medicines, supplements, allergies, previous raised scars, cold sores, and any tendency to heal slowly. Follow instructions for keeping the dressing clean and dry, applying prescribed ointment, and avoiding picking or rubbing. Protect the healing site from sun exposure after the wound has closed; sunscreen can help reduce lingering discoloration. Attend the planned review so a suture can be removed when appropriate and the scar can be assessed. Redness, tenderness, mild swelling, or a small amount of spotting can occur early in healing.

Contact the clinic promptly if pain, warmth, swelling, or redness is increasing rather than settling, or if thick drainage, fever, wound separation, or bleeding that does not stop with gentle pressure develops. Seek urgent help for facial swelling with trouble breathing, or for a rapidly spreading reaction. A new firm or enlarging scar should also be reviewed, because additional treatment may be needed.

Ask which scar is suitable, whether stitches will be used, how long the dressing should stay on, when normal skincare can resume, and whether later resurfacing or another scar treatment may improve the healed area.
