Inquiry regarding skin booster treatment for improving elasticity in dry and sensitive skin

Hello, seniors! I've always just been lurking and getting good information, but this time I'm facing a dilemma that I simply can't decide on my own, so I've mustered the courage to post a question.

I am an office worker in my 30s. My skin type is very typical dry and ultra-sensitive. Lately, every time I look in the mirror, I notice fine lines around my eyes and mouth, and I feel like my skin has lost a lot of elasticity, which makes me feel very depressed. Should I say that I suddenly look much older?

I simply can't manage it with home care alone, so I'm planning to get a dermatological procedure. After searching various communities and YouTube, I found many reviews stating that for combination or dry skin like mine, skin booster treatments like Rejuran Healer are a game changer for improving internal dryness and elasticity.

I have made up my mind and am trying to make a reservation, but on the other hand, I am so timid that I am losing sleep worrying about side effects. In particular, since my skin is very thin and prone to redness, I am most concerned about the following points.

Potential side effects for sensitive skin: For someone like me with a weak and sensitive skin barrier, would getting a skin booster (injection treatment) cause irritation that leads to breakouts or side effects like contact dermatitis? Is there anyone with sensitive skin who actually found their skin barrier strengthened after receiving the treatment?

Downtime and Embossing: How long do the bumpy embossing, needle marks, and bruising on the face usually last after the procedure? As a working professional, I am wondering if getting the procedure after work on Friday will result in them being covered by makeup by Monday.

Pain Level and Tips: I’ve heard so many rumors that the pain is excruciating that my hands are already sweating. Is it bearable with just regular anesthetic cream without general anesthesia, or are there any tips for choosing a hospital or specific procedure methods to make it less painful?

I desperately need honest advice from those with real experience. Even the smallest review or tip would be greatly appreciated, so I would be truly grateful if you could leave some advice in the comments! I hope everyone gets beautiful skin!
