What are the effects of Livicol, the collagen injection?

Lately, I’ve been really worried because it feels like my skin isn't just temporarily dry on the surface, but is sinking deep inside and losing nutrients. In particular, the volume around my nasolabial folds and cheekbones has dropped drastically, making me look much older than my actual age. I’m afraid that regular fillers might slide down or feel foreign later on, so while looking for a procedure that fills in naturally like my own skin, I discovered a skin booster called Revicol.

I think the biggest appeal of Revicol is that it doesn't look unnatural because it works on the principle of directly replenishing the collagen deep within the skin, rather than using artificial substances. I heard that it is similar to the trendy Juvelook, but with real collagen ingredients injected directly; is my understanding correct? Revicol is quite famous for improving sunken cheeks and fine lines that appear with aging, so I am really curious to see if the skin actually feels firm and plump after the injection.

Also, although it may vary from hospital to hospital, I would like to know the approximate price range per 1cc of Livicol, and how long the volume lasts after a single injection.

I want to achieve a naturally youthful face. Please give me some tips!
