If you're OK with animal products, I like plain old lanolin -- I keep a big tub at the house and use the little tubes marketed to nursing parents when I'm on the go (the tubes do say "for chapped nipples" in kind of big print, which is I guess a bit awkward ... but the stuff works!). Jars are normally with the health food stuff at the supermarket, and tubes in the aisle with the baby food.

I recommend that something on your lips has SPF in it. Balm, lipstick, etc. My grandmother had a cancerous growth removed from her lip.

Bite Beauty Agave Lip mask. I got it at Sephora, stupidly expensive but I put it on at night.

Also seconding paw paw, but I don't know where to find it in the US

Well, I started with the lanolin (thanks, Beck) and the petroleum jelly, because I had those on hand. The lanolin worked pretty well, but it tasted horrible (I put it on right before lunch, lol...let's just say it doesn't go well with watermelon). The petroleum jelly was too sticky and goopy for my taste.

Annagybe, I was just at Sephora today but hadn't read your comment yet! I'll keep the mask in mind. I like the Bite Beauty products.

I bought the Evan Healy lip balm (thanks, La Pedestrienne!)--saw it at the co-op tonight on sale by the cash registers. It's a nice consistency--not quite as thick as the lanolin, but still really substantial. I'll try this for a couple of days and see how it goes.

Thanks again, everyone!

Every single winter I struggle with chapped lips and spend a fortune on different lip balms none of which work for long. My current routine is lush lip scrub a couple of times a week, twice a day I wipe them with rosewater on a cotton pad, smooth on some melvita extraordinary water, give it a couple of seconds to dry and top that with Hydraluron, give that a couple of seconds to dry then put on some palmers concentrated cream. I try to remember everytime I go out to put on something that is thick to protect from the cold and wind. At night I add nuxe rev de miel on top. If they become cracked and bleeding I use Blistex relief cream. Hope you find some relief x

Personally I find that any lip balm with sunscreen makes my lips worse. Also sadly lipstick. Burt's Beeswax is my personal best lip balm. If you haven't tried it yet, give it a try. I also like Cold cream lip balm from Avene. It actually gives me a nice neutral color. But Burt's Bees is the absolute best from a healing and protection standpoint.

Pure Lanolin also worth a try.
