Is Rejuran a more painful procedure than expected?

I want to try skin care, so I'm looking into Rejuran.
Whenever I read reviews, I always find stories about pain.

I'm not really a fan of getting injections, so...
Even if the effect is good, I think I would hesitate a little if the pain were too severe.

Even if you use anesthetic cream
I can't quite get a sense of what it will feel like when I actually receive it.

Is it just a stinging sensation?
I am curious to hear from those who have experienced whether it is unbearable.

Are there others like me who are hesitating because of the pain? 🤔
