Hello! My name is Jessica, I am a physician assistant, and one of the providers at Aesthetic Skin in Winnetka and Chicago. This is a great question. After receiving your second treatment with EZ gel, noticing hard lumps under your eyes is not uncommon, but it is something that should be monitored closely. These lumps may be a result of localized swelling or the gel settling unevenly. While it's not unusual for temporary lumps or nodules to occur after dermal filler treatments, they often resolve on their own as the filler integrates with the surrounding tissue and any initial swelling subsides. However, it’s essential to keep an eye on these lumps. If they persist beyond a few weeks, or if they become painful, you should contact your injector or healthcare provider. They can assess whether the lumps are due to a minor issue with the filler placement or if there's a more significant concern. Sometimes, adjustments such as gentle massage by your provider or additional treatments might be needed to address unevenness or ensure the gel settles properly. I hope this helps and best of luck!
