i think u can get it overseas but in Australia...lucas paw paw ointment works WONDERS for dry/crackd lips, this can also be used for many other things burns/cracked skin/insect bites etc. i swear by this stuff.
What works best for me and I have been using this since 2000 is good old Palmers Coco Butter Stick it's the cheapest at walmart then any place else for about like 1.80 or so. I really keeps my lips moisturized for a long time you rarely have to keep applying it like carmex that useless yellow tube of junk.
my grandma told my mom, and my mom told me.
Good ol' fashion vaseline is the best moisturizor!
put an excess amount of carmex on at night. like a nice thick slab over your lips and in the morning your lips will be good as new because they have been absorbing the menthol, camphor, and phenol which helps bring back norm to your lips.
