I heard it's the ultimate solution for inner dryness. What are the features of Elavie Rituo?

I have extremely dehydrated skin that feels tight even in the summer...!!! The surface is shiny with excess oil, but after washing my face, it feels like it's going to crack. I use a 7-step skincare routine, but nothing works, so I decided to look into getting injections. I found so many recommendations saying there is nothing better than Elavie Rituo for inner dryness. Does anyone know what distinguishes Elavie Rituo compared to water-glow injections or other hyaluronic acid-based boosters? I heard that its biggest feature is that it strengthens the skin barrier, and I am really curious if, after getting the injection, my skin becomes so moisturized that it doesn't feel tight even when I just apply a cream.

I heard that it involves directly injecting collagen, so I'm curious to hear comparison reviews from those who have received both Rejuran and Rituo lol. I'll be waiting for your genuine reviews to see if it's worth enduring the pain!
