Who is Quadsay recommended for? Can I also consult about skin troubles?

I came across information about Maypure's Quad Say while looking for ways to manage my back acne and skin troubles. Since I haven't tried it yet, I would like to know first what specific skin concerns this treatment addresses. When listening to the description of who is recommended for Quad Say, I am curious if consultations are possible even if the treatment area is different, such as the face or back, and if there is a defined scope of application.

Since it is difficult to examine the back area in detail, I would like to have my condition assessed through a medical consultation rather than choosing a treatment based solely on appearance. I would also like to ask if the treatment approach differs depending on whether there are breakouts or remaining skin marks. If the Quadsay consultation does not address my specific concerns, could you please explain which areas I should check first?

I would like to know if I can receive a consultation first without deciding to proceed immediately. I would appreciate it if you could let me know if I can use products on my back as usual before the visit, and if there are any treatments I should avoid to check my skin condition. If it is possible to proceed, I would like to hear about the scope of treatment and post-treatment precautions before making a decision.
