A It can take a week or two for the swelling to completely leave your lips after having a lip augmentation. If you would be dissatisfied with your lips, you can have the hyaluronic acid dissolved with hyaluronidase. This enzyme will dissolve the filler, and reduce the areas of concern. If you wish to augment your lips again, you can be treated with filler in that area after two weeks has passed. You should call your injector to compare your before and after photographs and discuss your results.
