What are the characteristics of Vitaran as a skin booster?

I am curious about the unique features of the Vitaran Skin Booster. I would like to know what distinguishes Vitaran from other skin boosters. I am particularly interested in its ingredients and effectiveness; I would like to know what role the main ingredient, PN, plays in skin regeneration. I have also heard that Vitaran is specialized for thin skin and improving fine lines, so I am curious to know which skin types or concerns it is most suitable for. Furthermore, I would like to know about the pain level of the Vitaran procedure and the extent of post-treatment reactions, such as swelling or unevenness. I am also curious if the product is certified by the Ministry of Food and Drug Safety and which areas have been clinically proven effective. If anyone knows, please answer these questions.
