How many doses of Rivicol are recommended?

I was worried because I felt like my skin was losing elasticity lately. Livicol I learned about the procedure. Everyone around me says it's good, so I'm interested, but usually Livicol I am wondering how many sessions are recommended. While it may vary slightly depending on each person's skin condition and degree of sagging, generally speaking, to see results... Livicol I would like to know the minimum number of sessions required to experience satisfactory changes. I am seeking advice from those who have experience, wondering if a single session is enough to feel the difference, or if I need to sign up for a package of multiple sessions regularly. Since the cost is quite substantial, I would like to have accurate information in advance to make a plan. Please reply!
