How do you usually schedule your revicalls?

My skin condition has been deteriorating, so I am planning to get Revicol to properly take care of it. I’ve heard that treatments like this are usually divided into multiple sessions at set intervals rather than just a single one. I’m wondering what the ideal schedule is for Revicol to see real changes. I’m not sure if many people get it three times at 2 or 3-week intervals, or if it’s better to leave at least a month between sessions. Also, I’d like to know approximately how long the effects last once the cycle is followed. I would appreciate it if those with experience could share their recommended schedules.
