Is it true that this is the least painful among skin boosters?

My skin is so dry lately that it's a complete mess, so I'm frantically searching online to try a skin booster.

I was thinking about switching to Rejuran because I heard the results are amazing, but when I read the reviews about the pain—saying it feels like your face is being torn apart by needles—I'm such a scaredy-cat that I couldn't even bring myself to start...

Then I saw a post saying that Vitaran has almost the same ingredients but is much less painful because it has a thinner viscosity! I even heard that some versions come mixed with anesthetic ingredients, so it’s a piece of cake compared to Rejuran. Is this really true?

I'm so scared it will still hurt even if I slather on anesthetic cream. If anyone has tried both Rejuran and Vitaran, please honestly share the difference in pain levels.

I would appreciate it if you could let me know (_ _)
