When it comes to dermal fillers, it's important to understand how long it takes for the product to settle and the swelling to subside. Depending on the area and the amount of filler required, it can take up to 48-72 hours for the product to decrease. However, it may take up to two weeks for the entire fill to completely dissolve and settle naturally. 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 can be used. If you're not satisfied with the results after two to three weeks, you can inject hyaluronidase to dissolve the product. It takes time for the filler to break down, integrate with the tissue in the surrounding area, and begin to moisturize the skin.
It's important to note that there are a few exceptions when it comes to dermal fillers settling down or showing their full results. In some cases, it may take longer than two to three weeks for the filler to settle and show its full effects.
