How many sessions do I need to get the full effects of Rivicol?

Lately, as I've become more interested in skincare, I started looking into various things and came across a procedure called Revicol. At first, I thought Revicol was an ingestible product or a topical cosmetic, but after doing some research, I learned that it is a procedure involving the direct injection of collagen-based ingredients into the skin, which made me even more curious.

I've heard that Rivicol is particularly helpful for improving skin volume and elasticity, but I'm not sure if this is just temporary or if it's a natural improvement that develops over time. Looking at reviews from people who claim to have seen results, some mention their skin becoming more hydrated and firmer. I'm curious if this varies greatly from person to person or if it's a change that many people actually experience.

Also, I’ve heard that the application area and dosage of Rivicol vary depending on individual skin condition or problem areas. If so, I would like to know if the effects of Rivicol also differ significantly from person to person. I am particularly concerned whether this procedure is better suited for dry or skin lacking elasticity, or if it is also suitable as a preventative measure for relatively young skin.

I am also curious if there is a difference in the effects of Revicol when performed alone versus when combined with other skin treatments. I would like to know if there is a synergistic effect when combined, or if it is not strictly necessary to do so.

Above all, since it is a procedure, I am concerned about the pain and recovery period. I would also like to hear from people who have actually experienced it about how many sessions are needed to see the full effects of Revicol and how long the results last.
