4 weeks post op Upper Lip Lift, the incision isn't closing and there is stiffness. Is this normal? (photo)

Hi, I had an upper lip lift performed 4 weeks ago with internal & external sutures. The external sutures were removed 5 days post-op. Unfortunately, the incision isn't closed in places around the nostril (see attached pic). I have been alternating keeping it moist with Neosporin/Aquafor, & keeping it dry for a few hours every day. I fear that talking & eating keep stretching the incision. Could you please tell me if this & stiffness/inability to smile properly are normal at 4 weeks? Thank you!
