Hi Velvetee
I understand and sympathise but please dont use a petroleum based lipsalve of anysort again. For the reasons you have alreday discovered for yourself. Dryness, irritation, crusty lips, less moisture than before you started and so on.
Mineral oil or petroleum based balms and glosses, coat your lips like cling film. This effectively suffocates the skin and creates a catch 22 situation as you have already discovered. Lips get dryer so more balm applied and on it goes...
I broke the cycle with a petrochemical free balm from Innocent Oils
http://www.innocentoils.com/index4prod.html and now reguarly use their LITTLE GREEN BALM which is amazing, and can be used as a face moisturiser too!!! Belive me once you leave behind the chemicals you will never look back. :D
Best of luck and I hope you find a lip saviour soon. x
