How painful is Rejuran?

I am considering getting Rejuran, but my biggest concern is the pain. I am interested in improving my skin texture and elasticity, but since it is an injection procedure, I am hesitant to make an appointment because I am worried it might be more painful than I expected.

When I look at reviews, some people say it was bearable, while others say it hurt more than expected and brought them to tears, so I am curious about the actual level of pain. In particular, since it involves multiple injections across the entire face, I would like to know if the pain varies depending on the area treated.

I heard that anesthetic cream is applied during the procedure, so I am curious if the pain is significantly reduced if sufficient anesthesia is used. I would also like to hear from those who have actually experienced it about whether it is just a stinging sensation during the procedure, or if it feels quite painful when the injection goes in.
