Hi! I have that Maxim Labs PCA stuff in spray form-- to be used topically.

Also can be used in your scalp after shampooing. Its' supposed to restore the skin to the moisture balance it had when you were younger. Seems to work for my cheeks, as when I use it- the fine lines are gone for a few days.

I've also sprayed it in my hair (the version with the aloe added) and it seems to make my hair more managable.

I never took it internally though- maybe I have the wrong version.
