I'm curious about the effects of Rivicol!

I’ve been keeping an eye on Revicol because I heard it’s very popular these days for skin elasticity management. I heard that since it’s a procedure that helps stimulate collagen production, it’s especially recommended for those losing elasticity as they age. Lately, the firmness in my cheeks and jawline isn't what it used to be, so I’m curious to see if Revicol is really effective.
I heard that the effects of Revicol aren't immediately obvious but rather develop gradually over time. I would like to know how long it actually takes to feel the effects. I am also curious whether the effects appear naturally or if they are noticeable.
I am also wondering if a single session is sufficient to maintain the effects of Rivicol, or if I need to receive it periodically. Since the cost is not insignificant, I am considering continuing the treatment if the effects are proven, but I am also curious about the satisfaction levels of those who have experienced Rivicol.
