What should I do if one side of my face is larger than the other?

Facial asymmetry, such as one side of the face appearing larger than the other, can generally be corrected with botulinum toxin injections for facial slimming. Perfect facial symmetry is rare and quite normal. The asymmetry may result from insufficient sleep causing swelling, or from overdeveloped masseter muscles. If it's due to swelling, it's recommended to go to bed earlier, ensure adequate sleep, drink plenty of water upon waking, and regularly consume barley porridge to reduce puffiness. If you have a habit of chewing on one side, make sure to correct it promptly.
