This will decrease in 48-72 hours, depending on the area and the amount of filler required to dissolve, however, it will take up to two weeks for the entire fill to completely dissolve and settle naturally. The filling takes 2 to 3 weeks for the product to settle and the swelling to subside. I would try to wait and if at that point you still don't like the results, inject the hyaluronidase to dissolve the product. Most dermal fillers settle down or show their full results after 2 to 3 weeks, although there are a few exceptions.
It takes time for the filler to break down, integrate with the tissue in the surrounding area, and begin to moisturize the skin. Hyaluronic acid fillers, such as juvederm, can be dissolved with the enzyme hyaluronidase, which starts working almost immediately. Most hyaluronic acid fillers used on the lips, jaw and cheeks, including Juvederm and Restylane, are metabolized after 6 months to a year. There is no period of time during which hyaluronidase, an enzyme that can be injected to dissolve a hyaluronic acid filler (Juvederm, Restylane, Belotero), can be used.
