How many times is the usual recommended dose of Rivicol?

I am leaving an inquiry because I am curious about the recommended frequency for using Rivicol. Lately, my skin has been generally dry and dull, and the tightness on my cheeks lasts a long time after washing my face, so I was looking for a skin booster and came across Rivicol.

At first, I thought changing my moisturizer or ampoule would help, but even after applying multiple layers of basic skincare, I still felt dry from deep within. So I am looking into Revicol, but I am not sure if I can feel a change in my skin condition after just one session, or if I need to receive it consistently for a few sessions.

How many sessions of Livicol are usually recommended during the initial consultation? My skin is thin and sensitive, so getting treatments too frequently is a burden for me, but on the other hand, I feel like it would be a shame to judge the results after just one session.

I have an important event in about two months, and I am wondering when would be the best time to start Revicol to help refine my skin texture before then. I would also like to know if you can determine the recommended number of sessions and treatment frequency if I mention my schedule during the consultation.
