It is recommended to avoid exercise for at least 24 hours after lip filler treatment. Due to the swelling and tenderness that may occur in the lip area after the procedure, excessive physical activity or exercise may have negative effects on the healing process. Therefore, exercise should generally not be done for 1 week following lip filler injection in order for the filler injection to have the best results and for the lips to relax. Light exercises can be started once the swelling and tenderness have subsided. A doctor’s approval should definitely be obtained before moving on to heavy exercises.
