Even when I apply a generous amount of hydrating essence, it just sits on the surface. How about Celle Diem, which replenishes the skin barrier?

Lately, I feel like my skin barrier has completely thinned out and broken down. No matter how much ampoule or hydrating gel essence I squeeze onto my skin, it doesn't absorb and just sits there shiny on the surface. ㅠㅠ Even sitting in an air-conditioned room for just a short while makes the dryness in my cheeks feel like it's going to tear apart so severely that my face turns red quickly and my makeup cracks. I'm so stressed out I could die lol. I need something that delivers moisture deep into the cell layers and builds a firm barrier... Seldiem I'm really intrigued because I've heard the injection treatments are incredibly effective! If I get this, will my super-sensitive, dry skin—oily on the outside yet parched underneath—gain a subtle glow from deep within and make my makeup apply flawlessly? Do the side effects, pain, or embossed bruising fade quickly? Please, beauty veterans who have tried this before, share some real-life tips!
