Hyaluronic Acid Face Cream Can The Main Ingredient Of Restylane (hyaluronic Acid) Cross The Blood Brain Barrier?

Can the main ingredient of restylane (hyaluronic acid) cross the blood brain barrier? - hyaluronic acid face cream

I am a sensitive person and would like to fill out a face and Restylane. I feel much happier with a filling that I know he will not cross the blood-brain barrier. Does anyone know where you can prove in any case, when the hyaluronic acid may / may not be exceeded? I know from studies is the importance of a molecule of hyaluronic acid, but many prefer to see written specifically on the block. Thank you.

Of course I could get a collagen filler, since there is no possibility that the collagen of the blood-brain barrier to happen.
