Lip-Lick Cheilitis and Its Connection to the Brain.

An eight-year-old male who habitually licked his lips and presented with dry, flaky, and red skin bordering the outside of his lips was diagnosed with lip-lick cheilitis. This condition is exacerbated or, at times, caused by chronic lip-licking, leading to irritation and discomfort. Treatment included tacrolimus 0.03% topical ointment, which he was instructed to apply twice daily. He was also advised to stop licking his lips, maintain proper hydration, and use a stress ball when tempted to lick the irritated region. Following these interventions, there was a clear reduction in both irritation and redness. This condition frequently reflects psychocutaneous interactions, commonly observed in patients with underlying psychological stress, displaying the connection between the brain and skin.
