A coworker recommended this to me, saying it’s a must-have for Celé Diem. Does it really fix inner dryness?

I noticed my team member's skin texture had improved significantly lately, so I discreetly asked them about it, and they told me they have been consistently receiving Celle Diem treatments. I am always struggling because I have the typical dehydrated-oily skin type; after washing my face, my whole face feels dry and tight, but my T-zone gets oily.

I’ve heard that Celle Diem is incredibly effective for replenishing moisture deep within the skin and restoring the skin barrier, but since everyone has different skin types, I’m a bit hesitant to just blindly follow suit and stop taking it. I’m also worried about the injection marks and the long downtime, wondering if I’ll be able to cover them up with makeup the next day when I go to work. Are there any people with combination or sensitive skin like me who have received Celle Diem treatments and seen their inner dryness completely gone or their skin become firmer?
