Please give me your honest opinion on Vitaran for dry skin.

As I get older, my skin loses moisture, becomes rough, and looks completely lifeless. Since applying cosmetics alone isn't enough to address internal dryness, I am considering the Vitaran procedure, which contains salmon extract. I heard it has similar ingredients to Rejuran but is slightly less painful, so it seems perfect for someone like me who is a bit of a wimp. Still, since it is an injection, I expect it will be painful, but I am curious how long the embossing marks last and when I can comfortably apply makeup or resume daily activities after the Vitaran treatment. Most importantly, I would like to know how long the improvement in internal tightness lasts after the injection. I would really appreciate it if those who have undergone this procedure could share their valuable experiences.
