"If lip balm doesn't do the trick, you should consult a doctor"
Chapped lips can not only
be a sign of vitamin deficiencies, but also more serious conditions
particularly in children. Pellagra which results from a niacin or B3
deficiency is something that you shouldn't mess around with. It can lead
to death if not dealt with properly. Another issue that isn't very well
known is Kawasaki disease that primarily affects children under five
and can cause heart problems if untreated. Both of these disorders have
chapped lips as side affects although if you do more research there are
of course other side effects that accompany them. (source)
If you have chapped lips
constantly, make sure to check your chapstick for eucalyptus or
camphor, both of which actually dry out your lips instead moisturizing. (source)
If you can't get your chapped lips to go away, it would be best to
bring it up with a doctor and to not take it lightly. It may be an easy
fix such as a multivitamin, or something more serious if you have other
symptoms.
If
you want a great chapstick I live and die by Burt's Bees chapstick,
it's the only thing that makes my lips feel happy. I swear I have at
least one in each purse, my backpack, and my car. Do you have a solution
you use for chapped lips?
