I'm wondering if Celle Diem is suitable for inner dryness and skin barrier care.

As the seasons change, my skin feels severely tight after washing my face, and even after applying basic skincare products multiple times, it dries out again by the afternoon, so I am looking into skincare. Recently, the area around my cheeks easily turns red, and there have been many days where my makeup looks patchy, leading me to suspect that my skin barrier might have weakened. While searching online, I came across Celle Diem, and I am wondering if this treatment is suitable for skin like mine, which is both dry from within and sensitive. I would like to know the main features of Celle Diem, the effects I can expect, and whether it can help improve skin texture or hydration. How many sessions are usually recommended, and what is the treatment cycle, when effects appear, and how long do they last? I am also curious about the pain level, treatment time, post-treatment symptoms such as redness or stinging, and the recovery period. If I have an important event coming up, I would like to know if it is best to allow a few days of buffer time. I would like to receive a consultation regarding the price per session, the total cost for all recommended sessions, and maintenance methods. I am also curious about reviews from people with sensitive skin who have received this treatment.
