There is really very little to no downtime with the injectable hyaluronic-acid based dermal fillers, such as Restylane, Juvederm and Belotero. You can return to work right after your treatment, if that's what you desire. You may indeed have some swelling or bruising that can last for a day to up to a week or so, but you can control this by icing the area. If you develop a bruise, we invite our patients to come back to the office as soon as the day after the injection so that we can use a pulse dye laser at no charge to accelerate the resolution of the bruise. Some fillers, like Restylane Silk, swell more than other fillers, so it is important to discuss the choice of a filler with your physician. Also, feel free to mask the bruising with makeup; you can begin using that as soon as you receive your treatment. Be sure to consult a board-certified dermatologist about your lip injections so you will have the opportunity to have all your questions answered and your augmentation performed professionally.
