What if I were injected with an exosome injector?

I am considering an exosome skin booster to improve skin redness, loss of elasticity, and fine lines. I am most concerned about pain, so I am looking into it. While manual injections are available, I have noticed there are also various machine-assisted injections designed to reduce pain; I am curious to hear the experiences of those who have tried them. Is there a difference in pain and effectiveness when receiving exosomes via an injector (such as DermaShine, Hycoque, or Bellashine) compared to manual injections? Also, is there a significant difference in cost between the two?
