Is Rejuran Healer definitely effective for treating inner dryness and dullness of the skin?

Perhaps because the seasons have changed, my skin's internal dryness has become much worse lately; it feels so tight it feels like it's going to tear after washing my face. No matter how much moisturizer I apply before bed, my skin looks rough and dull in the morning. Since I've lost elasticity, my makeup just sits on the surface and cakes, so I get incredibly stressed every time I look in the mirror. Just then, I saw that the community was running various events as a check-in, so I decided to leave a post to ask for other members' opinions and gather some information regarding skincare that I've been keeping an eye on.

I am seriously considering the procedure because Rejuran Healer is so famous for improving the skin barrier and restoring inner elasticity, and everyone recommends it. I heard that since it uses PN ingredients extracted from salmon, it regenerates the skin itself to be healthy, so I am curious to know how satisfied those who have actually received the treatment at a clinic were with the changes in their skin. I am a bit scared because I’ve heard it has a notorious reputation for being one of the most painful skin boosters ever; is it manageable without applying numbing cream for a long time or needing general anesthesia?

I would also like to know how many sessions are typically recommended to experience the noticeable firming and long-lasting effects of achieving radiant skin. I am curious how long the downtime—such as uneven texture, bruising, or redness immediately after the procedure—usually lasts, and whether it would be feasible to get treatments over a weekend while working. Although prices may vary from person to person, I would be grateful if you could generously share any approximate cost information or helpful tips on how to get the treatment painlessly in the comments.
