What happens if I get Juvederm lip filler when I'm hungover?

Why would you? Alcohol causes bleeding and bruising, which can compromise a good result and add swelling. This is especially true for the lips. Have it done 10 days after your next bender!

Alcohol use prior to surgery or injections, can lead to  more bruising.  Best of luck with your lip injections when you decide to do it.

It won't affect your ultimate results but alcohol will thin your blood somewhat. When the bruises heal, the results should be similar to if you hadn't drunk.  I'd do it on a day you are feeling better.

Alcohol will act to dilate (or open) small blood vessels . This can cause an increase in bruising and bleeding with the procedure. As with any procedure, it is important to go in with a clear head so that you can understand the risks and full informed consent. Best Regards, Dr. Stutman
