When do you usually get your 3rd Rejuran session?

I received my first session in late May and my second in early July, and it has been about eight weeks since the second. I originally planned to get up to the third session around August, but it kept getting postponed because I was busy with work. Still, after the first two sessions, I definitely feel like my skin texture, internal dryness, and makeup flaking have improved, so I am thinking of getting the third one. However, I am wondering if it is okay to have a gap of about two months, and what the typical interval is for the third session. I’m worried that I might have put it off for too long!
