I like EOS in the warmer months, but it's original Blistex all the way during the frigid winters where I live. Both also work well as a base for my lipstick, so that's always a plus.
EOS is my favorite because it's very soft and smells good, but when my lips are REALLY chapped I put petroleum jelly on them, they sell little tubes of it. I also like tinted lip balms but not always because sometimes the area above my lips is also dry and I don't want it to look red haha
Theres this brand that uses the metal against your lips, the cream flows out slowly from the small cracks in the metal. IT FEELS AMAZING, plus the one I had smelled like cinnamon buns, so thats a good thing.
Something i learned the hard way: be careful of lip balm with menthol or mint in it. While it feels cool to put something on and it tingles, over the long haul it causes irritation on your skin, so over time, it makes your lips drier. Which of course requires you to put on more lip balm. Its a vicious cycle. Also true for high contents of alcohol.
