There are certainly options for improving lower eyelid hollows. First of all, a thorough examination in person by a qualified oculoplastic surgeon would be necessary to fully evaluate the area to see if there's anything specifically contributing to the hollow appearance. Hollows can be addressed by lower lid blepharoplasty with fat repositioning, hyaluronic acid fillers, or fat injections. There are pros and cons to each procedure and depending on your specific exam, one option may be more appropriate for you than another. However, an evaluation would be necessary to be more specific.
