In brief: Many things

Classically vitamin B12 or iron deficiency is the text book answer, but in the us today, this type of inflammation is more often caused by topical trauma, such as wind, cosmetics, or mouth pieces used in some sports.
Some medicines cause the mouth and lips to become dry, and occasional allergic reactions to meds or foods have been reported.

In brief: Angular cheilitis

Angular cheilitis, or cheilitis of the angles of the lips, is usually associated with dental procedures, flossing, change in bony structure/bite, reactions to oral hygiene products and secondary yeast infections.
Retinoids, wind-burns, and allergies may aggravate the condition. Chronic lip licking is a common cause of cheilitis in young children as the saliva causes a repeated irritant dermatitis.

In brief: Several possiblities

The most common cause is simply dry skin or some irritation followed by constant lip licking.
Denture wearers with an over-closed bite is another common cause. Fungal infections, vitamin deficiency, stretching the lips during dental treatment are among some other causative factors. If this is a recurrent problem see a dentist and or physician.
