I'm curious about the reviews for Livicol. Who is it recommended for?

My skin looks drier and less vibrant than before, so while looking into various treatments, I came across a lot of talk about Revicol. I am interested in Revicol, but I am curious about who receives it and who is most satisfied. My skin tone is dull, and I often experience dryness, so I would like to know if it is helpful in this case. I became even more interested after reading reviews from people who have received Revicol, as some mentioned their skin looked much clearer and their overall condition improved naturally. However, since everyone's skin condition is different, I would like to hear actual experiences regarding who it is recommended for. I am also curious whether it is a treatment that first-timers can start without feeling overwhelmed, or if it requires multiple sessions to see results. Since I don't usually spend a lot of time on skincare, I would like a treatment that is manageable for me. If anyone has experience with Revicol, it would be very helpful if you could share what kind of skin it is recommended for, the reasons for your satisfaction, and any aspects you found lacking.
