I am curious how long the subtle glow and hydration on the skin surface usually last immediately after the procedure.

I’ve been doing a lot of research lately, and I’d like to try the Celle Diem treatment, which is said to replenish moisture and vitality from deep within the skin. My skin is usually dry and dull, so I’m drawn to the Celle Diem procedure because it is known to be effective for internal dryness and improving skin tone. I’m curious how long the subtle glow and hydration on the skin surface typically last immediately after the procedure. I’m hesitant to pay if it reverts to its original state within a week or two. I want to know if I need to receive it regularly to maintain the condition, or if it feels like it helps build the skin's natural regenerative abilities. Also, I have one more question: please let me know if it is safe for sensitive skin without worsening breakouts.
