How long does it take to recover from the pain and embossing marks after Rejuran Healer?

Hello! With the recent change of seasons in autumn, my skin has become very dry from within and seems to be losing elasticity, so I am considering a skin booster treatment. People around me have strongly recommended Rejuran Healer, saying it is very effective for skin regeneration and deep hydration, so I am planning to get it. However, I have a few concerns before the procedure, so I am posting this question to ask for advice from those who have experienced it.

My biggest concern is definitely the pain. I’ve heard that Rejuran is notoriously painful among injection procedures; is it unbearably painful even with anesthetic cream applied? I am also wondering if undergoing general anesthesia or receiving pain-relieving laser treatment along with the procedure would be helpful in reducing the pain.

Secondly, I would like to discuss the embossing (bumped marks) that appear after the procedure and the recovery period. I have heard that the skin becomes raised along the injection marks immediately after the procedure; how many days does it usually take for these embossing marks to completely subside so that I can resume my daily life? As a working professional who needs to go to work, I am curious to hear firsthand accounts from those who have actually experienced how long bruising, swelling, and marks last.

Lastly, please share any tips you have regarding the procedure, such as how many cc is typically needed to see overall effects and how often the treatment should be repeated to maintain the best results! I will make sure to reply to every comment you leave. Thank you!
