Can smoking a cigarette 5 hours after lip injections cause you to get a bump?

Thank you for sharing your question.  Though unlikely I would reach out to your injector to be seen.  Perhaps the product can still be manipulated to avoid a lump from forming.  Hope this helps.

Having a cigarette after lip augmentation should not cause a lip bump. One should give approximately 10 to 14 days after the treatment. If the bump does not disappear, one should have a follow up with their treating physician.

No relation, your bump is either product placed too superficially, too much product in the one area, or a bruise, your specialist physician can advise you on what it is via an examination. Most cases self resolve. Dr Isobel Walker. Brisbane. Australia.
