Filler dissolving refers to the process of using an enzyme or injectable solution to break down hyaluronic acid-based dermal fillers, which are commonly used for facial rejuvenation. This procedure can be used to correct overfilled areas or to reverse the effects of fillers if the patient is not satisfied with the results.The filler will be broken down and will disappear in a matter of minutes. However, the results of the treatment are usually only apparent after 24 hours (once any swelling has gone down).
