2 sessions of Soprano Ice 2018 Diode Laser. 3rd session w/ Soprano Platinum laser. What is the best time between sessions?

Hello I have had 2 sessions of Soprano Ice 2018 Diode Laser and the third session with Soprano Platinum laser since March . Length of time between sessions was equal (1 month). Should I continue taking sessions with the same interval or do I need to lengthen it?
