Postinflammatory hyperpigmentation - 發炎後的皮膚色素增生https://en.wikipedia.org/wiki/Hyperpigmentation
發炎後的皮膚色素增生 (Postinflammatory hyperpigmentation) 是一種皮膚病,其特徵是皮膚發炎後皮膚色素增加。 發炎後的皮膚色素增生 (postinflammatory hyperpigmentation) 可能是由長期日曬、發炎或其他皮膚損傷(包括與痤瘡相關的損傷)引起的。膚色較深的人通常更容易因過度日曬而出現色素沉著。

      Postinflammatory hyperpigmentation (PIH) 是皮膚發炎或受傷後常見的皮膚問題。它往往會持續很長時間,並且對於膚色較深的人來說情況更糟 (Fitzpatrick skin types III–VI) 。儘管它通常會自行好轉,但這可能需要一段時間,因此通常需要長時間的治療。結合不同的治療效果最佳。
      Postinflammatory hyperpigmentation (PIH) is a common acquired cutaneous disorder occurring after skin inflammation or injury. It is chronic and is more common and severe in darker-skinned individuals (Fitzpatrick skin types III–VI). While the condition typically improves spontaneously, this process can take months to years, necessitating prolonged treatment. Combination therapy is the most effective.

      Postinflammatory hyperpigmentation 是皮膚發炎常見的後遺症。它往往對深色皮膚的人產生更嚴重和更頻繁的影響。研究表明,諸如 postinflammatory hyperpigmentation 這樣的問題是膚色較深的人尋求皮膚科護理的主要原因之一。早期治療對於解決 postinflammatory hyperpigmentation 至關重要,通常從控制最初的發炎狀況開始。第一線治療通常涉及使用美白皮膚的外用製劑以及防曬霜進行保護。這些藥劑和 hydroquinone, azelaic acid, kojic acid, arbutin, licorice extracts 一樣,可以有效減少過度色素沉澱。此外, retinoids, mequinol, ascorbic acid, niacinamide, N-acetyl glucosamine, soy 也被用作脫色劑,新的治療方法不斷湧現。雖然局部治療通常對錶面色素沉著過度有效,但對於頑固病例可能需要手術( laser, chemical peel )。重要的是要謹慎對待這些治療,以避免 postinflammatory hyperpigmentation 受到刺激和惡化。
      Postinflammatory hyperpigmentation is a common sequelae of inflammatory dermatoses that tends to affect darker skinned patients with greater frequency and severity. Epidemiological studies show that dyschromias, including postinflammatory hyperpigmentation, are among the most common reasons darker racial/ethnic groups seek the care of a dermatologist. The treatment of postinflammatory hyperpigmentation should be started early to help hasten its resolution and begins with management of the initial inflammatory condition. First-line therapy typically consists of topical depigmenting agents in addition to photoprotection including a sunscreen. Topical tyrosinase inhibitors, such as hydroquinone, azelaic acid, kojic acid, arbutin, and certain licorice extracts, can effectively lighten areas of hypermelanosis. Other depigmenting agents include retinoids, mequinol, ascorbic acid, niacinamide, N-acetyl glucosamine, and soy with a number of emerging therapies on the horizon. Topical therapy is typically effective for epidermal postinflammatory hyperpigmentation; however, certain procedures, such as chemical peeling and laser therapy, may help treat recalcitrant hyperpigmentation. It is also important to use caution with all of the above treatments to prevent irritation and worsening of postinflammatory hyperpigmentation.
