Rejuran Healer pain concerns

I am considering the Rejuran Healer procedure to improve skin elasticity.

I've heard a lot of people say it's effective.
I am hesitating because there are many reviews saying the pain is severe.

Even though they say they use anesthesia, I keep seeing reviews saying it still hurts.
I don't have a sense of how much it actually is.

Also, because it is not a one-time procedure that needs to be repeated several times
I am also wondering if it is worth enduring the pain.

I am curious to know the standards of those who have actually experienced it regarding the level of pain relative to the effectiveness.
