What are the advantages of Livicol?

Perhaps due to the weather lately, my skin has become so dry from within that my makeup looks cakey and is a total mess. No matter how generously I apply my basic skincare products, they feel like they are just sitting on the surface, so I think I will eventually need the help of a dermatological procedure. While searching for various things on online forums, I often saw posts about Revicol, which contains collagen. Has anyone here tried this treatment? There are so many types of skin boosters these days that I'm having trouble deciding which procedure to choose. I'm wondering if Revicol is suitable for a skin type like mine that is severely dry from within and looks dull. I'm also concerned about whether it would be safe to receive it alongside other firming treatments. If anyone has personally experienced Revicol, I would be very grateful if you could share the honest benefits!
