My lotion (Lubriderm Advanced Therapy) has, in bold letters on the back, this message:
For external use only.
I guess I can only think of a couple internal uses that people might be contemplating. I wonder what the danger is... overmoisturizing? Whenever I see instructions and warnings like that, I always want to know why. Sometimes it's obvious (do not put Listerine into eyes), but in this case, it's not.
