I just found this thread and had a thought.
A person's hydration/dehydration levels could definitely alter the appearance of the lips. Am not meaning to pick on Dixie but if you look at her comparison pics, I would say the one with more vertical lines was at a more dehydrated point. I also believe Dixie is correct when she restated the rep comment she received. The mouth tends to become dryer as excitement builds. Just my 2¢ and thanks to those who posted pics.
