How many times is recommended to get the full effect from Elavie Rituo Skin Booster?

Lately, my skin has been thinning, losing elasticity, and developing fine lines, so I am planning to get skin regeneration injections. I heard that Rejuran is very painful, so I was recommended Elavie Rituo, which is relatively less painful and contains a high concentration of salmon DNA (PDRN). I heard it is very effective for achieving a dewy glow and repairing the skin barrier.

I’ve heard that since this treatment fundamentally improves the skin's internal environment, you need to receive it multiple times rather than just once to achieve truly flawless skin. How many sessions do clinics typically recommend for Ellavie Rituo to see noticeable results? I’m wondering if the standard approach is to get at least three sessions at intervals of 2 to 3 weeks. For those of you with thin, dry skin like mine who have received Ellavie Rituo, I would appreciate it if you could let me know at which session it took for your face to start glowing from within and regain elasticity!
