Instead of running ions through metal casings full of toxic and corrosive substances like lithium and alkaline, Enfucell uses a thin paper sheet as a conduit.

Yet recurrent bouts of diarrhea not only disrupt a child's schooling, but also retard physical development as vital nutrients are continually flushed out of the body.

The Food and Drug Administration has not yet approved a UVA rating system but has approved some ingredients that protect against UVA rays. Look for broad-spectrum sunscreens that contain Parsol 1789, zinc oxide, titanium dioxide or the newly approved Mexoryl. And reapply often, even on cloudy days...
