Has anyone actually experienced the effects of Rejuran?

I've been seeing a lot of reviews lately saying that Rejuran is effective, so I've become interested.
I looked it up and it says that it helps the skin recover from within and naturally makes it more elastic. I'm curious to know how much of a change people who have actually had the procedure have felt.

In particular, I would like to know how long the effects of Rejuran last and whether there are differences depending on the number of treatments.
I have sensitive skin, so I'm worried about whether I'll be able to see results without irritation.

I'm also curious about whether I can return to my daily life right after the procedure and what management tips or precautions I should take.
If you have any honest reviews from people who have experienced the effects of Rejuran, please share them.
I'm contacting you because I want to experience the natural skin recovery process myself.
