My skin's internal dryness has become so severe.

I am very worried because my skin's internal dryness has become so severe. It feels tight after washing my face, and even when I apply a generous amount of moisturizer, only the surface looks shiny while my skin underneath feels constantly parched, as if it is about to tear. My makeup also keeps flaking and looking rough, so I looked it up and heard that Vitaran injections are good for treating internal dryness, which is why I am asking for your advice.

People often get water-glow injections or other skin boosters for inner dryness, right? Does Vitaran have any unique advantages? I wonder if getting Vitaran will really fill my skin with moisture from deep within, even for severe inner tightness that hasn't been resolved for a long time like mine... It looks so good just from the reviews. Also, I'm worried it might get bumpy afterward... Even if it does, it should go down after a while, right?

Either way, I hope the dryness gets resolved.
