It's just part of collagen or some type of protein or interstitial fluid that helps the skin slide over the muscle tissue....and since FF is very high in amino acids, I'd say the collagen is more abundant in animals fed on FF. Just a guess, not a fact, mind you.

So would this collagen be good to smear all over my face?
It IS like an addiction, isn't it? I've seen people who never do anything with technology get one of those phones and pretty soon they cannot leave their hands off of it. Even when they don't get cell service they will keep bringing it out of their pocket and caress it, fondle it, look at it, turn it on, off, back on.....I expect to hear them say, at any moment, "My precioussssssssssss!"
