I heard that it is recommended by Celre Diem. Has anyone heard of it?

Lately, my skin has been oily on the surface but feels incredibly tight underneath, so I stopped by a clinic on my way home from work for a consultation. I originally went thinking about the most common options like Rejuran or exosomes, but after looking at my skin condition, they recommended Celle Diem.

I heard this is a treatment that's popular these days for barrier care and tackling inner dryness, but honestly, since it's a name I've never heard before, I hesitated to pay and just left. I can't really tell if the Celle Diem treatment actually makes a noticeable difference in deep hydration or skin texture, or if it's just a new package deal they're pushing these days.

Has anyone here personally tried Celle Diem or is receiving regular care? Please share your realistic opinions on whether the procedure was really effective for inner skin tightness or smoothing out uneven skin texture.
