Before the procedure, your doctor may use a numbing cream or local anesthetic on your lip and mouth area. Also, many lip fillers contain lidocaine, a numbing agent, so getting lip filler is not painful. There may be some pressure or pinching from the needle injector during the procedure, and you may experience some pain or tenderness immediately after the procedure. However, most patients find the procedure itself nearly painless and the recovery fairly quick and easy.
There is virtually no downtime after lip filler injection and you can resume normal activity right away. However, there may be some temporary soreness, redness, bruising, or swelling in the area immediately after injection. Gently apply ice to the lip area to reduce swelling. Avoid applying any lip or skincare products to the area until the swelling goes down. Any redness or undesired swelling around the injection site should subside within a day.
There are also very few side effects from lip filler injections. However, your doctor may test you in advance to determine if you are allergic to any of the ingredients in lip filler.
