Who would benefit from receiving Livicol? I'm curious about who it would be recommended for.

I've become interested in Revicol because I've been seeing a lot of posts about it on Instagram and in online forums lately. I've heard it's good for improving elasticity since it works by directly nourishing collagen, but I'm curious exactly who would benefit most from it. For instance, is it more suitable for people concerned about fine lines, or for those worried about overall facial sagging?
I am hesitant about procedures that are too excessive, so I am curious whether this treatment is suitable for anyone regardless of skin type, or if there are specific skin conditions that require avoiding Revicol. I am also curious about how many people are getting this treatment these days. I look forward to hearing valuable opinions from those who have experience with the procedure.
