Even when I apply a generous amount of regenerating cream, it just sits on the surface. Is Celle Diem really effective for improving the skin barrier?

Maybe it's because my skin has become extremely sensitive and thin, but no matter how much hydrating ampoule or regenerating cream I squeeze out and apply, it doesn't absorb deep into my skin and just sits there shiny on the surface. ㅠㅠ Even sitting under the air conditioner for a short while makes my face feel so tight deep inside that it feels like it's going to tear; I feel like my skin barrier has completely collapsed, and I'm so stressed out I could die. Haha. So many people highly recommend the Celle Diem Skin Booster, saying it's the best for building the barrier because it fills the skin with healing substances and moisture deep inside! Even if it suits my super-sensitive, dry skin—which is shiny on the outside but cracks like a desert underneath—will it really soothe that inner tightness without any side effects? ㅠㅠ Please give me some genuine advice on Celle Diem: how long the embossing marks or bruising last, and whether it really strengthens the barrier. Haha.
