Cheilitis - 唇炎
口紅可能是個重要原因。
Angular cheilitis ― 大多數情況下，伴隨輕度感染，因此需要抗生素治療。與皰疹感染不同，嘴唇上常會出現濕疹。

這種疾病可以單獨出現，也可以作為某些更廣泛的健康問題（例如維生素 B12 或鐵水平低引起的貧血）或局部感染的一部分（ herpes, oral candidiasis ）。唇炎也可能是由於對刺激性或過敏性物質的反應而發生，或者可能由陽光 (actinic cheilitis) 或某些藥物（尤其是類維生素A）引發。已有多種形式的唇炎報道 (angular, contact (allergic and irritant) , actinic, glandular, granulomatous, exfoliative and plasma cell cheilitis) 。
The disease may appear as an isolated condition or as part of certain systemic diseases/conditions (such as anemia due to vitamin B12 or iron deficiency) or local infections (e.g., herpes and oral candidiasis). Cheilitis can also be a symptom of a contact reaction to an irritant or allergen, or may be provoked by sun exposure (actinic cheilitis) or drug intake, especially retinoids. Generally, the forms most commonly reported in the literature are angular, contact (allergic and irritant), actinic, glandular, granulomatous, exfoliative and plasma cell cheilitis.

○ 光化性唇炎
主要是由陽光引起的，影響白人。從長遠來看，這種情況有可能發展成鱗狀細胞癌。
○ 過敏性唇炎
它分為內源性（由於個體的固有特徵）和外源性（由外部因素引起）。內源性濕疹性唇炎的主要原因是異位性唇炎，外源性濕疹性唇炎的主要原因是刺激性接觸性唇炎（例如舔唇習慣引起的）和過敏性接觸性唇炎。
過敏性接觸性唇炎最常見的原因是唇部化妝品，包括口紅和潤唇膏，其次是牙膏。輕微的接觸，例如親吻塗口紅的人，就足以引起接觸性唇炎。對金屬、木材或其他成分過敏會導致音樂家，尤其是木管樂器和銅管樂器演奏者的唇炎反應，例如所謂的「單簧管演奏家唇炎」或「長笛演奏家唇炎」。
○ 治療 - 非處方藥
如果只出現在上唇，可能是因為長期過度陽光照射造成的。避免陽光照射並定期去看醫生。避免使用口紅或潤唇膏成分，因為它們會引起過敏。使用非處方類固醇乳霜和服用非處方抗組織胺會有幫助。
