I'm going crazy because my skin feels so parched deep down.

I have tried layering everything from highly moisturizing toners and ampoules to ceramide creams that are said to be good for dryness, and even mixing in a drop or two of face oil. However, the oil film on the surface only makes my skin look shiny immediately after application; deep down, my skin still feels tight and as if it is about to tear, like it is on dry land. Even when I apply makeup, it looks dry, flaky, and cakes around my chin and mouth, so my complexion looks incredibly dull every time I look in the mirror.

No matter how much makeup I slather on the surface, it feels like moisture isn't reaching the dermis layer.

People around me say that skin boosters like water-glow injections or Rejuran are the most effective for tackling inner dryness. For chronically dry skin like mine, where the surface is oily but the inside is cracked and peeling, which treatment with which ingredients would best strengthen the skin barrier and resolve inner tightness?
