Does the improvement in skin elasticity appear immediately after getting a Rivicol injection?

Lately, it feels like fine wrinkles are deepening all over my face, and I am particularly worried about severe internal dryness where my skin cracks deep down after washing it. Even when I apply a generous amount of highly moisturizing cream that is supposed to be good for elasticity, it only makes the surface look shiny without restoring firmness from within, so I am looking into cosmetic procedures. I saw on the Maypure review board that a collagen injection called Revicol is getting very good reviews these days.

I heard that since it contains highly concentrated collagen extracted from pig placenta, it strengthens and restores the skin barrier and brightens the complexion. Is this true? I am wondering if there will be any irritation or side effects if someone like me, with thin, sensitive skin that turns red easily, receives Rivicol.

For those who have actually received the treatment, I would like to know at which session you began to clearly feel the effects of Revicol. I am looking forward to honest answers from those with experience regarding whether you feel a tightening sensation after just one session, or if you usually need to proceed with a package of at least three sessions to prolong the results.
