I'm looking into the price of Rivicol; would it be too expensive?

I have recently become interested in skincare and am comparing various treatments, and I am most curious about the price of Revicol. When I look up Revicol, it seems there is a significant price difference between clinics, so I don't have a sense of what a reasonable price is. Since this is my first time trying Revicol, I hesitate to choose a place that is too expensive, but conversely, I am also worried about places that are too cheap. I am also curious whether the price difference is due to the volume used or the treatment package. I would like to know if there are any promotional events, and I would appreciate it if you could share your experiences to get an idea of ​​the average cost for a first-time treatment. It would be a great help if those who have actually received the treatment could honestly share whether the satisfaction was good relative to the price and whether they would be willing to get it again.
