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。

References這種疾病可以單獨出現，也可能是某些更廣泛健康問題（例如維生素 B12 或鐵水平低引起的貧血）或局部感染（如 herpes、口腔念珠菌症）的組成部分。唇炎亦可能因對刺激性或過敏性物質的反應而發生，或因陽光（actinic cheilitis）或某些藥物（尤其是類維生素 A）所致。已報告多種唇炎形式，包括 angular、contact（allergic and irritant）、actinic、glandular、granulomatous、exfoliative 以及 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
主要由陽光引起，常見於白種人。長期下來，可能演變為鱗狀細胞癌。
○ 過敏性唇炎
分為內源性（因個體固有特徵）與外源性（因外部因素）。內源性濕疹性唇炎的主要原因是異位性唇炎；外源性濕疹性唇炎則多由刺激性接觸性唇炎（如舔唇習慣）或過敏性接觸性唇炎引起。
過敏性接觸性唇炎最常見的致因是唇部化妝品，包括口紅和潤唇膏，其次是牙膏。即使是輕微接觸，例如親吻塗口紅的人，也足以誘發接觸性唇炎。對金屬、木材或其他成分過敏的患者，常見於音樂家，尤其是木管與銅管樂器演奏者，會出現所謂「單簧管演奏家唇炎」或「長笛演奏家唇炎」。
○ 治療 - 非處方藥
若症狀僅出現在上唇，可能是長期過度曝曬所致。應避免陽光直射，並定期就醫。避免使用含致敏成分的口紅或潤唇膏。使用非處方類固醇乳霜或服用非處方抗組織胺可緩解症狀。
