Antioxidants in a Nutshell—Pistachio, to be Precise

Researchers from Tufts University in Boston had a nutty idea: What if pistachios could provide skin benefits? As it turns out, this wasn't such a tough nut to crack.

Advanced Methods Measure Skin Penetrants at the Parts-Per-Billion Level

Healthy and intact skin was formerly considered an impermeable barrier designed to shield the living organism from all types of environmental injury, and certainly offering protection from all things chemical. Now skin is recognized as a semi-permeable membrane. Microorganisms cannot penetrate it, but it is pervious to chemicals, selectively allowing molecular passage in and out of the skin.
