When does the Elavie Rituo effect begin to appear?

My skin elasticity has dropped significantly lately, so I'm looking into skin boosters, and I've seen many reviews saying that Elavie Rituo is effective.

I've heard it's particularly excellent for regeneration. How many treatments are typically required to see the actual effects of Elavie Rituo?

Whether you can feel the effects of Elavie Rituo with just 1 to 2 uses,

Alternatively, I am wondering if I need to get injections consistently for the true effects of Elavie Rituo to appear. I would also appreciate it if you could let me know the duration of the results after the procedure.

Have a great holiday.
