Cant really judge on one picture. But it seems your lips are still inflamed. And what I know is that peeling wont stop until inflamtion is gone.
Few months ago i reported that my corners were healed. Because the inflamtion was gone in the corners of my lips, top and bottem. Till this day there are no EC symptom on the corners. And if it peel once a while, the skin underneath is already 'healed'.
