Drink plenty of fluids. Having 8-10 glasses of water per day is ideal. When your body is dehydrated, it often shows first in your lips. T
Don't lick or pick at your lips.
Reapply lip balm or ointment after drinking or rinsing out your mouth.
Exfoliate your lips. Before applying any sort of ointment, remove the dead skin using an exfoliation method.
Apply an ointment. Be careful which over-the-counter ointment or lip balm (e.g. Chapstick) you use to heal
your cracked lips. Many contain ingredients (e.g. Camphor
or petroleum jelly) that make lips feel better temporarily, but which may actually dry out your lips even more, forcing you to reapply them again and again.
Look for a lip balm that contains beeswax, shea butter, coconut butter, almond oil, or other natural moisturizers - and not much else. A vitamin E or glycerin-based ointment containing other natural ingredients could also be helpful.
Consider your diet
. Increase the amount of needed vitamins in your diet by eating better or taking supplements like vitamin pills.
Refrain from eating salty foods, which increase the urge to lick your lips.
Use a fluoride
free toothpaste. Avoid smoking
and tobacco chewing.
