Skin concerns in my 30s… How are the effects and pain levels of Rejuran?

My skin texture looks so dry and rough, so I'm considering Rejuran. I'm wondering if it's really effective.

People around me say that Rejuran is better for fundamental skin improvement than water-glow injections, but I've heard a lot of stories about it being painful, so I'm hesitating...

For those who have received it, how painful is it? Is it quite painful even with anesthetic cream applied? I am also curious if it is effective after just one session, or if I need to receive it consistently over several sessions!

I would like to know if it was okay even for someone with sensitive skin like me, and if there were any side effects such as breakouts or redness.

Please share an honest review of your satisfaction with Rejuran, based on skin in your 30s.
