Very Effective Medically
As a PhD in biochemistry I know this biochemical is normally present in our blood. I did not realize that taking extra doses of it could have beneficial effects on the skin. I am not the one using but a family member reports a big decrease in acne and bumpy arms as a result of taking it. Also some dark spots are clearing up.
