Question) Is the Rejuran procedure very painful?

Lately, I feel like my skin texture and elasticity have decreased, so I am considering getting a Rejuran treatment. However, I am hesitating because I heard the pain is very severe. I am even more conflicted because I heard the results are good.

I heard that they apply anesthetic cream, but I'm wondering if it will still be unbearable, or if it's manageable compared to what I expected. I'm especially worried because it's a procedure that covers the entire face, so I think it will be more painful.

For those who have actually received this treatment, I would like to know how much pain you experienced and how long the swelling and bruising last. Please also honestly share whether the satisfaction is high enough to justify enduring the pain compared to the benefits.
