How long prior to pregnancy can I get lip fillers?

There are no studies that I am aware of that can answer that question. Restylane and other fillers are not recommended during pregnancy, but there is no information on injections prior to a planned pregnancy. Most likely it is completely safe, but in the absence of data to prove that, it may be best to just wait until after you have delivered. Best of luck!

Thank you for sharing your question. There have been no problems seen with the injection of fillers 4 months prior to pregnancy. Discuss with your doctor before receiving the treatment.Good luck.

Fillers have not been studied during pregnancy for obvious reasons.  There have been no reports of systemic effects from fillers that are used in the lips.   Hyaluronic acid fillers are analogs to components of our natural collagen and get degraded naturally by the body with no short term or long term side-effects other than risk related to the injections themselves.  Theoretically, you could get a lip filler done the day before you are pregnant without any adverse risk.
