For those who have received the Revicol procedure, how long do you feel the effects last?

Lately, my skin has become increasingly dry from within and seems to be losing elasticity, so I am looking into skin booster treatments. I happened to see a new event currently running in the community, so I am posting this to ask for other members' opinions and gather information regarding a treatment I have been keeping an eye on. Among the various products, the Revicol treatment appealed to me the most because it claims to directly replenish collagen and seems to be very popular these days with great reviews.

I have high expectations because I heard it provides firming elasticity from deep within the skin, but I am curious about the satisfaction levels of those who have actually received the treatment at the clinic. Since I am enduring the cost and pain to get this, the most crucial factor is how long the effects of Rivicol last. I would like to know how many of the recommended sessions I typically need to receive after the first treatment to experience the proper effects of Rivicol for a long time.

I am curious to see if there are any noticeable changes in skin texture or fine lines, and I would also like to know the pros and cons compared to other skin boosters. I plan to take this opportunity to properly take care of my skin, so I would be grateful if you could generously share any vivid reviews or tips from those who have actually used this product.
