I'd like to know reviews or care tips for Vitaran.

I would like to inquire about the Vitaran procedure, a regenerative injection containing salmon extract. As I age, my pores have widened and I feel my skin barrier has significantly weakened, so after much consideration, I am planning to receive a skin booster treatment. After searching for reviews online, I saw many posts stating that Vitaran is relatively less painful and provides high satisfaction for skin regeneration and hydration.

I am wondering if the pain is tolerable with just the anesthetic cream during the procedure. Is redness or swelling severe immediately after the injection? I am seeking advice from hospital staff or those with experience regarding the satisfaction level of the before-and-after results when receiving the Vitaran procedure in one's late 20s or early 30s.
