Is Rejuran okay even if I have a history of other skin treatments?

I am looking into Rejuran to improve my skin texture, but I am hesitant because I have previously received other skin treatments.

I am concerned that past treatments might affect my current skin condition, and I am also wondering what information I need to disclose in advance.

To what extent do they check treatment history or the timing of procedures? If I cannot accurately remember past treatments during the consultation, how should I explain it?
