What is this spot in my lip? Does it have anything to do with fillers? (photos)

Thank you for your question and photos. Based on the images, it does appear some additional waiting time may be prudent. If you are still unhappy with your appearance in two weeks, I would schedule a follow-up with your injector. It is possible you might like your result better if you remove a...

You don't have to have the definition of your upper lip area as a result of fillers.  It is due to the technique used by your injector.  Discuss your treatment goals including what you want as well as what you don't want prior to your next injection.

Vomiting is not a symptom that is associated with fillers.  It is likely a coincidence that you had an episode of vomiting after your treatment.  Other countries may have different standards than the US for their products and practices, so it is hard to comment on this without knowing more.

It is not uncommon to feel the filler at this point after treatment.  It is due to swelling which typically resolves within two weeks of treatment.  If you do not notice improvement by then, return to your injector for an evaluation.
