For those of you with rough, dry skin, have you tried the Celle Diem treatment?

Lately, no matter what moisturizer I apply, the inner dryness doesn't go away, and my makeup keeps caking, so I'm so stressed out ㅠㅠ It's really upsetting... After looking online and reading reviews, it seems like Celle Diem treatment is getting the best response these days for replenishing moisture deep within the skin! Is that true? They say it fills moisture layer by layer from the dermis, so after receiving Celle Diem, the skin becomes firm and the complexion becomes clear... The cost is a bit steep, and I'm worried that if I get it, the effects might wear off quickly. Still, it's the hottest treatment these days, so I'm curious. If any of you have actually tried Celle Diem, please share your genuine reviews! I'd appreciate some honest tips on whether your inner dryness was completely resolved after the treatment and how long the results last.
