I tried Rejuran, but honestly I did not feel a big effect. I did not notice my skin texture improving dramatically or my pores shrinking a lot, and even when I compared photos I could not really tell a dramatic difference.
The procedure itself was fairly painful, and I got a little bruising too, but considering that, my satisfaction was just so-so. I know they say you need several sessions for the effect to show, but even after a few treatments I still did not see the kind of change I was expecting. It is not exactly cheap either, so that made it feel even more disappointing.
It probably suits some people well, but at least for me I do not think I would do it again. Personally, it was a procedure I had too high expectations for.
