How many syringes of filler do I need for under eyes?

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. For my patients who wish to avoid surgery, we use fillers, lasers, microneedling/PRP and stem cells. I suggest getting a formal evaluation with an expert to discuss your aesthetic goals and develop a treatment plan best suited for you. Best, Dr. Emer

Based on your photo I would start with at least one syringe of a filler, Boletero perhaps. If necessary can add one more.
