Blistex Med plus. It's amazing! I got it for my son whose lips were cracked and bleeding (he has ASD and kept picking at them <shudder>) and although he hated having it on a couple of swipes a day and three days later his lips are fine
I tried some today as my lips are dry and cracked in the corners and it feels amazing! It's kind of hot and cinnamony, you can feel it working iyswim.
