I have (on more occasions than i care to remember) waxed my nose hair and made feable attempts to wax my ears. As I get older my nose and ears have staged a joint operation to grow crazy amounts of hair that serves no known earthly purpose. There was also a time where my aunt offered to wax my back...that sucked. I should have know it wasn't going to go well when she couldn't contain her giggles as she applied warm wax with a roller and pressed cloth strips to it. She applied the wax/strips to my entire back before initiating what would become a 45 minute cylce of slow ripping, laughter (from her), crying and running away (from me). I won't do that again.
Now the nose is done using a thick hot (microwave) wax applied to a stick and shoved into the nostril. Sounds easy enough but having a mustache makes this a rather delecate event...one made even more difficult by the requisite consumption of liquid courage (bourbon). The last waxing resulted in a large peanut sized portion of my mustache being removed. The combination of strong hold on the intenal crop of nostril hairs, skin and the suction that is created by the airtight seal makes ripping the wax tipped stick quite difficult. And surprisingly painful, particularly when you give that good ole yank only to find you failed to actually rip the wax plug from your nostril. I would welcome a roomtemp option, perhaps one with better precision and maybe a topical anesthetic.
There was also that one time I had a superglue accident that resulted in my goatee and mustache being glued to my face. That wasn't pleasant and resulted in a more patchy removal of hair and skin that you might be looking for.
On a more constructive note. I have been told applying some baby poweder to the skin prior to waxing makes it less painful. I wonder if using medicated (menthol) talc would help?
