My skin is very dry; are there any advantages to Elavie Rituo?

I have extremely dry skin that feels like it’s going to tear apart as soon as I wash my face, no matter how hot or humid the weather is ㅠㅠ😢😢😢 I’ve tried the 7-skin method and slathered on expensive moisturizers, but it just looks shiny on the surface while my skin feels like it’s cracking deep inside, so I just can't stand it anymore. I heard that skin boosters are the surefire way to tackle inner dryness, so while researching, I discovered the Ellavie Rituo treatment. Compared to other famous "water glow" injections or skin boosters packed with hyaluronic acid, if I had to pick just one or two distinct advantages that only Ellavie Rituo possesses, what would they be? If the effects of Ellavie Rituo—filling my skin with moisture from deep within and strengthening the skin barrier—are truly proven, I am 200% willing to pay for it right away. Those of you who have experienced this, please help me!😭
