Between Rejuran and Juvelook, what criteria should someone using a skin booster for the first time use to make a choice?

All I've done so far is get toning treatments occasionally, so I've never tried any direct facial treatments using injections. However, since the beginning of this year, I've felt like my skin suddenly looks thin and lacks firmness, so I started looking into skin boosters.

It's a bit difficult to pick just one skin concern.

It’s not like I have huge pores or deep wrinkles, but overall, my skin looks less vibrant than before, and fine lines under my eyes become more visible after I smile. When I’m barefaced, my skin texture also looks a bit rough. I just feel like I want to improve my overall skin condition by one level.

So I started searching, but Rejuran comes up, Juvelook, and the types just keep popping up, so I have absolutely no idea what to do haha.

I've seen a lot of discussions about Rejuran and Juvelook, and it seems quite a few people are debating between the two. Some people say they received Rejuran for their skin texture, while others chose Juvelook for pores or elasticity, so I'm wondering what criteria I should use to make a decision as someone with ambiguous skin like mine.

Do you choose a specific product before you go for your first skin booster consultation? Or is it a process where you simply discuss your skin concerns and receive recommendations tailored to your current condition?

Also, if anyone has tried both, I'm curious if the tactile sensations are very different. I'd like to know if there is a clear distinction, like how one makes the skin feel moisturized and smooth, while the other makes it feel firm.

What I value most is naturalness. Rather than my face looking suddenly different, it would be perfect if one day people around me could say something like, "Your skin looks better?"

I've seen mentions that three sessions of skin boosters are generally considered the standard, so I'm wondering if it's a good idea to plan accordingly from the start. Would it be okay to try one session first to see my skin's reaction and satisfaction, and then get additional sessions later?

I'm also realistically curious about the level of pain. I've heard a lot of people say Rejuran is quite painful, so I'm a little scared. I'm wondering if it hurts a lot even with numbing cream, and if it's bearable since the procedure itself is short.

Please also let me know about the condition of my face immediately after the procedure. I am curious if the embossing or redness will subside in a day or two, and if I have an important schedule, I should leave a gap of a few days.

I'd appreciate it if those of you with actual experience could share your thoughts on which one you chose when you first started using skin boosters, and whether you would choose the same one again if you could go back to the beginning.
