Fillers like Belotero, Volbella, and Restylane Silk are good for improving under the eyes, but keep in mind that a combination approach will give the most improvement. My patients try to get non-surgical treatments to avoid surgery, so we use fillers, lasers, microneedling/PRP and stem cells. I suggest consulting with an expert to develop a treatment plan best suited for you. Best, Dr. Emer
Ligaments do not contract like muscles and therefore are not affected by Botox. There are many other treatments for the undereye area including PRP injections and dermal fillers. Filler placed in the cheek area can often improve the undereye area without directly treating it too.
