Lip fillers are safe, when they're properly injected by an experienced provider. There's a common misconception that filler will stretch out your lips and leave them misshapen, but that's not the case with HA-based fillers. Your skin is elastic enough that it won't be stretched to the point where it becomes lax. As your body metabolizes the filler, your lips will gradually return to their original shape.

Your provider should mention potential side effects during your initial consultation. The most common side effects are temporary swelling, bruising, and soreness at the injection site.
As we mentioned, more serious potential side effects include infection, allergic reaction, or scarring, as well as blindness or tissue death if the filler is accidentally injected into a blood vessel and not quickly dissolved.Â
Because of these risks, it’s vitally important to make sure you're visiting a board-certified plastic surgeon, dermatologist, nurse injector, or another qualified medical provider who understands safe technique and is equipped to handle any problems that might occur post-treatment.
If you experience intense pain or drastic discoloration of the skin after your appointment, call your provider right away.
RealSelf Tip: Most providers recommend avoiding lip fillers while you’re pregnant or breastfeeding. As with most cosmetic treatments, very little testing has been done on patients who are pregnant, so it’s safest to err on the side of caution.
