What is the duration and maintenance of Vitaran?

I am writing to inquire about the duration of VitaRan's effects and how to maintain them. I am looking into skin boosters due to skin texture issues, internal dryness, and enlarged pores around my nose, and I would like to know how long the effects last after the initial few treatments.

I am curious whether the effects of Vitaran appear immediately and disappear quickly, or if it is a method where skin condition gradually improves over time and is maintained for a certain period.

Does the duration of Vitaran's effects vary significantly depending on skin type, lifestyle, and the recommended frequency?

I would like to know if I need to continue receiving treatments every month after the initial intensive care, or if it is possible to receive Vitaran treatments every few months as a maintenance routine. My skin is sensitive, so I find frequent treatments burdensome, and I want to consistently manage my skin texture and hydration without overexerting myself.

During the consultation, can I receive guidance on a long-term plan that includes not only the initial recommended frequency but also the subsequent maintenance cycle????? Really?!!!!!!!!!!!!!!!!!!!!!!
