Is there a big difference in pain and effectiveness among Juvelook, Sonjusarang, and Mirajet (Potenza)?

I'm currently looking into dermatology clinics to get Juvelook injections!

After looking at reviews, I found that some places administer the injections manually, while others use equipment like MiraJet or Potenza.

I heard that hand injections are injected directly into the dermis layer, so there is less loss and the effect is better. Is that true?

I tend to be a real drama queen, so is the hand injection very painful? I'm curious if MiraJet or Potenza are much less painful.

I'm also curious about the difference in downtime (embossing vs. bruising). As an office worker, I'm concerned about going to work, so which one would be better for me to get?
