I was told to use a straw to drink after my Juvederm lip filler. How long should I use a straw for?

This is certainly not standard post-treatment advice, and I cannot think of a scenario as to why this would be recommended. I would advise you to drink as you wish straight away. 

Thanks for the question. I have never told any of my patients to use a straw after lip fillers and I cannot see the benefit of this. I would suggest getting in touch with your injector and asking them.

Hello,
We've never suggested this for any of our lip filler patients. Try giving your injector a call about this. I can't think of a reason why it might be necessary. 
Best of luck!

Thanks for the question.
