One of the frequently asked questions about dermal fillers is why they would need to be dissolved. It is important to note that there are several reasons why this may be necessary. These include if the patient is not satisfied with the treatment outcome, if the product has migrated to an undesired area, or if there is a Tyndall effect (blue appearance) that the patient is not happy with. Additionally, dissolving the filler would be required in emergency situations such as a vascular occlusion.
