What is the treatment cycle and duration of the effects of the Maypure Elavie Rituo injection?

Hello. I am a member in my 30s seriously considering a skin booster treatment to regenerate my facial skin barrier and address my severe internal dryness. My skin is naturally sensitive, so I am afraid of laser treatments causing irritation. However, I became very interested in the Elavie Rituo treatment because I heard it enhances the skin's natural regenerative power by directly injecting nutrients. But I have heard from others that while the injection itself is convenient, the results are not permanent, so periodic maintenance is essential.

So, I have a question: on average, how long do the effects of Ellavie Rituo typically last after a single treatment? I am curious if the duration of the effects varies significantly depending on an individual's original skin condition or daily home care habits. Also, to maintain the initial clear and hydrated skin condition beautifully for a long time, I would like to know roughly how much time needs to pass before I go back for a follow-up treatment before the effects completely wear off. I have heard that with skin booster treatments like Ellavie Rituo, you need to receive about three consecutive treatments at one-month intervals initially to build up the cell regeneration effect and extend the duration; is this really true?
