I'm so stressed because my face turns red easily. How effective is Vitaran?

Lately, no matter what skincare products I use, my inner dryness doesn't go away, and my face turns red easily, so I'm really stressed out ㅠㅠ. After looking online and reading reviews, it seems like Vitaran injections are getting the best response these days for improving the skin barrier and replenishing moisture deep inside.

I heard that because it contains salmon extract PN, it replenishes moisture layer by layer from the dermis, making the skin firm and changing its texture after getting Vitaran... It sounds amazing just reading about it. However, I'm hesitating to pay for it because I'm worried about the injection marks or bruising lasting a long time, and I'm afraid the effects might wear off quickly. If anyone has actually tried Vitaran, please share your genuine reviews! Also, please give me some honest tips on how long the effects last.
