I am curious about the features of the Vitaran procedure for improving the skin barrier :-)

I am worried because my skin has become sensitive and severely dry from within, possibly due to fine dust and the changing seasons. In particular, it feels like my skin is breaking out constantly. I am looking for information on Vitaran, a treatment said to aid in skin regeneration and replenish moisture, as I wish to regain a healthy skin condition :-)

I have heard that Vitaran, with PN extracted from salmon as its main ingredient, is excellent for improving the skin's internal environment. I am curious about how it differs from general hydration treatments, and when I can expect to feel my skin becoming firmer after the Vitaran procedure. Is it effective?

I want to improve my skin texture to make it look naturally healthy rather than having an artificial glow. For those who have actually received the treatment, how satisfied were you? I would appreciate advice from those who have experienced Vita-ran on whether this is a procedure that is burdensome to receive regularly while working.
