Under-Eye Rejuvenation With Hyaluronic Acid Filler: New Insights and the Role of Imaging
Hyaluronic acid (HA) fillers are now very popular for improving the appearance and restoring lost volume under the eyes. However, treating this area presents unique challenges, as the aging process creates anatomical changes that make the region especially sensitive and demand careful technique.
Key findings and highlights:
-
With aging, changes such as reduced skin elasticity, fat and muscle atrophy, and ligament laxity can result in puffiness, dark circles, and other esthetic concerns under the eyes.
-
Main complications include: migration or displacement of the filler (seen as puffiness, malar mounds, or discoloration), formation of granulomas, overfilling, and negative effects from excessive hyaluronidase use.
-
Recent studies using MRI and ultrasound imaging have shown that HA fillers can remain in the tissue for several years—highlighting the need for caution with frequent reinjections.
-
Injections should be performed carefully, using appropriate technique (in the preperiosteal plane with a cannula) and with low volume (maximum 0.5 ml per eye per session).
-
Appropriate patient selection (individuals with mild to moderate volume loss and healthy skin) leads to the best under-eye results.
-
Imaging, especially MRI and ultrasound, helps physicians detect residual filler or potential complications before any additional treatments or surgery.
-
Alternative methods such as PRP, laser, and radiofrequency also provide effective, noninvasive under-eye rejuvenation.
Summary:
Under-eye filler treatment with hyaluronic acid demands up-to-date knowledge, experience, proper patient selection, and the use of imaging tools to minimize complications and achieve optimal results.
