Does the skin booster work?

Maybe it's because I haven't been getting enough sleep lately and I'm so tired, but every time I look in the mirror, I can really feel how dull and rough my skin looks. I feel like home care just doing face masks and applying cosmetics has its limits, so I'm thinking of biting the bullet and getting some dermatological treatment.

I've seen a lot of people recommending skin boosters in beauty communities and forums. I tried Rejuran once before but didn't really feel any effect... Honestly, are skin boosters effective?

I am really curious if there are noticeable changes worth the money in improving my recently worsened internal dryness, fine lines around my eyes, and drastically reduced elasticity. I would also like to know how many sessions I need to receive consistently to see the proper effects of the skin booster.

For those of you who bought these products with your own money (not advertisements), which product were you most satisfied with? Since I'm visiting the dermatologist anyway, I want to see proper results, so please share some genuine reviews!
