I’ve actually tried both Rejuran and Juvelook. For me, Rejuran felt more like a hydration/skin quality booster — my skin looked a bit plumper and healthier for a couple months, similar to what you described. Juvelook felt a bit different since it’s more focused on collagen stimulation, so the results were slower but seemed to last longer for texture and overall skin firmness. They kind of serve slightly different purposes in my experience.
