Because you are operating on cheekbones and mandibular angle, the swelling process may be slower. Generally, the swelling began to decrease in 5-7 days after operation, and basically recovered in half a month, and completely recovered in 1-2 months.
Everyone's physique is different, and the time for detumescence and recovery is also different. You should do a good job of postoperative care first to ensure the final surgical effect.
