I've been getting a lot of inquiries about skin boosters lately. How effective are they?

Lately, my skin feels generally dry and dull, and my makeup doesn't apply well, so I've been looking into skin boosters a lot.
I originally tried to manage with just home care, but I gradually started to feel inner dryness and a subtle loss of elasticity, so I realized I needed to take better care of it.

I became interested because I heard a lot of people around me saying their skin texture improved after getting Rejuran, exosomes, or water-glow skin boosters, but I am having trouble deciding because there are so many types.
I inquired about skin boosters, and since the treatments recommended vary from clinic to clinic and there is a significant price difference, I don't know what criteria to use to choose.

What I'm curious about is whether I can actually feel the improvement in skin texture or internal dryness, and how long the effects last.
Also, when I see people inquiring about skin boosters, I'm very curious about how long the pain, swelling, or bumps last.....

If anyone has received this, please share a review telling me which product you received and how satisfied you were!!
I would especially like to hear recommendations for skin boosters that are suitable for dry and thin skin types...!!!
