Lip augmentation procedures, whether using fillers or another method, can cause some discomfort or pain during the procedure. However, most procedures use a local anesthetic or numbing cream to minimize any discomfort. After the procedure, there may be some swelling, tenderness, and redness, which should subside within a few days. Generally, people report that the experience of getting lip augmentation is relatively quick, with little downtime afterwards. It's important to discuss any concerns or questions about the procedure with your doctor beforehand to ensure a comfortable and successful experience.
