Vitaran, a skin booster specifically for the eye area, pain

My fine lines and dark circles under my eyes are getting worse, so I am seriously considering Vitaran, a salmon injection specifically for children.
The skin around the eyes is the thinnest and most sensitive part of our face, so I'm scared that the pain will be tremendous when the needle goes in.
Even if I apply a generous amount of numbing cream, I'm worried if I'll be able to endure the pain of the needle going in.
If there are any brave members out there who endured the pain of VitaRan at Maypure without general anesthesia and got tighter eyelids, please share your vivid reviews of the procedure!!

Please give me lots of information regarding pain with Vitaran, such as tips on how to tolerate the pain better during the procedure or how long the embossing lasts!!!
