After 12 to 24 hours, your pain should go away. Your swelling should go away after 24 to 48 hours, but it may take up to a week. If you want your lips filled before a big event, like a wedding, you should schedule the procedure at least two weeks ahead of time to make sure you’ve completely recovered.

It’s best to wait to eat until after the topical anesthetic or nerve block injection has worn off so you don’t accidentally bite your lips and disturb the filler. You should also avoid eating any messy foods that may cause you to wipe your face or lips for at least 24 hours.

Avoid drinking straws or smoking for at least 24 hours, as well. Puckering or contracting your lips may disturb the lip filler, too.

You should also avoid drinking alcohol for at least 24 hours, as alcohol thins your blood, which can make bruising on your lips worse.
