Will Rejuran be extremely painful? Will it be bearable?

As I get older, signs of aging seem to be getting worse. I am debating whether to get procedures like Rejuran or Jubarek because of internal dryness and fine lines that even makeup can't cover. I've read reviews of Rejuran saying the results are 확실 (certain/definite), but I'm scared by the description that it feels like having holes pierced in my face. Is the pain bearable for an average person? I tend to be a bit of a crybaby, so I'm already terrified. I'm also curious how long the raised marks on the face last. If I get the procedure on Friday afternoon, will they be barely noticeable by the time I go to work on Monday? I'm also wondering if there are any ways to alleviate the pain.
