Lip filler causing other lines to worsen?
Getting your lips filled can cause your nasolabial folds (the lines from the nose to the corners of the mouth) to look more prominent sometimes. Usually this is due to post-procedure swellin. You can have some residual swelling for a full 10-14 days, so I usually ask a patient to wait 10 days after lip fill to address this. It is likely to get a little better every day. If you still notice this effect after that wait, it can be corrected by your injector and you should book a follow up exam to get it touched up if you need it! Good luck!
Smile Lines from Juvederm
Juvederm lip cosmetic injections have possible side effects that may range from mild to moderate. So, yes it could possibly be the cause. However wait up to two weeks to allow the fillers to even out and soften to truly evaluate results.
