No one wants cracked lips and I know for sure that your partner don't enjoy it either. Everything needs to be exfoliated and moisturize and lips are included. I heard of those honey and sugar remedy but why not double the duty when you brush your teeth? Yes, put your tooth brush and toothpaste to another use. Once a week, exfoliate these babies and moisturize EVERYDAY.
Wet lips with water just a little. Slab on a thin layer of toothpaste and let it sit for 30 seconds to a minute.
Wet tooth brush and gently scrub your lips until the toothpaste work a lather. Scrubbing for at least a minute and wash off. Pat dry and don't forget to moisturize.
***Save on those expensive tube of lip balms and buy yourself a tub of Vaseline. A small $2 tub totally last me a long time, I'm not even half way and it's been 2 years since I bought it. Just dab some on and you're good to go. use vaseline twice a day to keep your lips hydrated and don't forget lots of water.***
