Can I kiss or suck some one lips after the lip filling with Juvederm?

Once the lips are injected with juvederm it is best to avoid passionate kissing for at least a week to avoid shifting of product.

It is best to avoid hard or harsh manipulation for a few days after Juvederm is injected. That doesn't mean you can't kiss your partner, but just do it gently for a bit. "This answer has been solicited without seeing this patient and
