How do you usually schedule the treatments for the Juvelook 3-session package?

I am thinking of purchasing the 3-session Juvelook package to improve my pores and fine lines.

Is it usually most effective to get 3 consecutive injections at intervals of 3 to 4 weeks and then stop?

I am wondering how many months after I finish all 3 sessions I should wait for the next maintenance treatment (touch-up).

I understand that it might be difficult to stick to the schedule strictly due to my work schedule, so I would like to know if there is a significant difference in effectiveness even if I slightly miss the interval (e.g., every 5-6 weeks)!
