What is the treatment cycle for Livicol?

I am worried because my skin elasticity has dropped rapidly recently, and fine lines under my eyes and on my cheeks have increased noticeably.

An acquaintance recently recommended a procedure called Revicol that replenishes collagen. It seems a bit different from the skin boosters or fillers I commonly hear about, so I became curious and am posting this on the Q&A board.
I heard that Revicol provides an immediate volume effect even right after the procedure, while simultaneously inducing self-collagen production.
For those who have actually received it, I am curious whether it feels like fillers that plump up naturally without an artificial look, or if the texture is similar to regular skin boosters.
I've heard it's usually recommended to do it about 3 times at one-month intervals, so I'm curious about your personal experience regarding how long the results typically last after completing the entire course.
I am also worried about the pain during the procedure or the extent of the embossing.
It would be very helpful if you could let me know whether severe redness or embossing remains immediately after the procedure to the point where it cannot be covered even with a mask, and when I can resume daily activities or light makeup.
Since the price range isn't exactly cheap, I want to do thorough research before making a decision. I'm curious if I can actually feel the effects of improved elasticity or texture refinement on my thin, firm skin!
