Hi there!
It is good that you have read about Rejuran and Ellanse. However, my short answer is that neither were created for the purpose of improving dark eye circles, and saggy skin/wrinkles under the eyes.
I agree with Dr. Pang's opinion on use of energy-based devices such as monopolar radiofrequency (RF) and high-intensity ultrasound (HIFU) for skin tightening and collagen stimulation as a first-line for mild-moderate cases of saggy skin and wrinkles.
As for dark eye circles, those due to volume loss such as “tear trough” deformities are best treated with a “soft” undereye filler. There are many brands available, but in general hyaluronic acid based fillers e.g. Teosyal Redensity II are preferred for this delicate area for a natural-looking appearance. For this reason, ellanse is not commonly used for under eye fillers.
As for rejuran, rejuran healer and rejuran for eye can be used in the area. However, the major benefit of a PDRN/PN treatment is for biorevitalization (e.g stimulating collagen) and not to treat areas of volume loss such as a tear trough deformity.
In addition, there are other conditions associated with dark eye circles and eye bags such as hypertrophic tarsal muscles and venous congestion around the eyes, which are not treated with rejuran or ellanse. Do seek out a consult with a trusted doctor for more information!
Regards,
Dr. Joanna Chan
