I'm really curious about the specific pain and benefits of Livicol, which is said to be popular these days!

Hello! I think the dryness has reached its peak lately, probably because the office heater has been on all day. By the afternoon, I can hear my skin cracking, and I can feel the loss of elasticity clearly in my jawline, so I'm looking into skin boosters as an emergency measure. I used to get Rejuran injections regularly because they are known for their regeneration benefits, but the pain was so intense that tears streamed down my face every time I got them that I just couldn't bring myself to go back. Even if I apply a thick layer of numbing cream that practically paralyzes my face, it hurts so much every time the needle goes in that I'm practically developing a trauma from it.
So, I was desperately searching for an alternative skin booster that is less painful yet still provides good hydration and regenerative effects, and I found out about a product called Revicol recently because it's been trending in online communities! I heard it contains ingredients that help with collagen production, so it strengthens damaged skin barriers and is amazing for improving fine lines, inner radiance, and elasticity.
Most importantly, I've seen many reviews saying that because it has lower viscosity than Rejuran Healer, the stinging sensation from the medication entering is less and it is less painful during the procedure. Since this seems to be the biggest advantage unique to Livicol, I'm easily swayed and really falling for it haha. If anyone has recently received Livicol, could you honestly tell me if the pain is really bearable enough to smile about? Also, I'm curious how long the embossing marks or bruising usually last! I'm a working professional, so I have to get it on the weekend and go to a meeting on Monday; it would be a problem if my face looked too obvious like a frog's ㅠㅠ
Also, besides improving skin texture, I’ve heard that Revicol is also effective for pore tightening and brightening the complexion. I’m curious if you actually experienced those effects. Please share your genuine review—how it compared to the skin boosters I used to use—and what aspects you found more satisfying and what were lacking! I’m also curious if there were any side effects. If the benefits of Revicol are undeniably perfect for me in many ways, I want to book an appointment this weekend and rush over to get some radiance back on my dull face lol. Please leave lots and lots of comments!
