(Question) What are the actual effects of Rejuran Eye?

My current concerns are fine lines around my eyes and dark circles caused by thin skin underneath, where blood vessels are visible. Dark circles have been a concern since childhood, and I am worried about always looking tired. I have tried diligently with home care using eye creams and patches, but they haven't been effective, so I am considering a procedure. I learned about Rejuran specifically for eyes, so I am curious about reviews from people who have actually used it. Is Rejuran Eye effective for dark circles? I am worried about pain since it is near the eyes; what is the pain level like? Are there any side effects? What is the approximate cost? How many sessions are required? Please share this information.
