well, I think skin is a great mystery, because I had a slob roommate in college who was lived off of stuff like pop-tarts and pizza (ONLY junk food) and as a result she was grossly overweight, and all she did was skip class and watch TV. Also she never washed her face daily, just a little rinse when she was in the shower, and somehow she had the MOST perfect and beautiful skin! It was like a baby's butt, so smooth and simply gorgeous. How can I explain that?! My guess is that she is SO full of toxins from her 110% unhealthy lifestyle that NO toxins are escaping whatsoever, they are only accumulating, thus no toxins excaping from her skin. Still puzzles me, to this day.
