How long after Juvederm lip injections is it safe to have oral sex?

The barriers of the skin and mucosa (if lips were injected) are compromised due to the injection needles and can allow transmission of communicable diseases or STDs as they are surgical wounds (minuscule but they are still wounds). The swelling can cause additional discomfort. Waiting few days is advisable until injection sites have healed. Safe sexual practices are also advisable to all sexually active individuals. 

Thank you for your question. I recommend avoiding this for 1-2 days after your treatment or until all swelling has resolved which can take up to 2 weeks.It is unlikely oral sex has caused displacement of your filler.  I recommend addressing your concerns with your injector. Best of Luck!

Thank you for
your question. It would be safer to wait until 24 hours for the injection sites
to close or until you feel comfortable. Also, you may want to wait until all
bruising and swelling is resolved in 1-2 weeks. If you have any other concerns
please contact your injector. Good Luck!
