How long does subcision take to work for acne scars?

During subcision, a fine instrument releases fibrous bands that pull a depressed scar downward. Initial swelling or bruising can temporarily make the surface appear smoother, so an early look is not the final assessment. As the area heals, new collagen and tissue support can change the contour. Rolling scars that are tethered may respond more readily than scars with sharply defined edges, and more than one treatment may be considered.

Follow the clinic’s wound-care instructions, keep treated skin clean, and avoid pressing, picking, or strenuous activity for the advised period. Protect the area from strong sun while it heals. Attend the planned review with comparable photographs and report medicines that affect bleeding before any further session. Do not judge the result while bruising, tenderness, or swelling is still changing.

Contact the treating clinic if pain, warmth, redness, drainage, or swelling is increasing rather than settling. Urgent assessment is needed for fever, spreading redness, severe pain, or an allergic reaction with facial swelling or breathing difficulty.

Ask whether your scars are tethered and how long your clinician wants you to wait before judging the contour. Discuss whether a different scar treatment, combination approach, or another session is appropriate for your scar type and skin tone.
