I umm waxed my upper lip for the first time in my entire life 6 years ago and pretty much ripped off the entire epidermis. (I usually thread).
Anyhow so I had this dry scaley layer forming overnight, i couldn't smile or eat because of how dry it was. Had to slather on major amount of vaseline to keep it moist. To make matters worse, it was my cousins college graduation next morning, which I tried getting out of but his wife gave me such a guilt trip about his immediate family not being there. So I went. With vaseline running down the sides of my mouth. Sigh.
Needless to say waxing the upper lip is now out of question.
