摘要炎症后色素沉着是皮肤炎症后过量色素沉积导致的结果,是临床常见的症状之一,尤其好发于深色皮肤的人.它是一种获得性色素增加疾病,在黑素生成过程中,任何一步发生改变都能够导致其发生.国内外一直在进行其发病机制的研究,目前尚不完全清楚.外用维A酸、氢醌、壬二酸、曲酸和化学剥脱术可一定程度地改善病情.近来有报道证实,某些激光可以加速色素的去除,这或许是未来研究热点之一.

abstractsAs a result of excessive pigment deposition secondary to an inflammatory dermatosis, postinflammatory hyperpigmentation (PIH) is a common clinical entity and has a predilection for dark skin phenotypes. It is an acquired hyperpigmentation that can be caused by alterations occurring at any level in melanogenesis. Although studies have been carried out at home and abroad, litde is known about its pathogenesis. Topical tretinoin,hydroquinone, azelaic acid, kojic acid and various types of epidermal peels have shown some therapeutic effect. Recent reports also have demonstrated the efficacy of some lasers in accelerating the pigment removal, which may serve as a hot topic in future research.
