Postinflammatory hyperpigmentation
Postinflammatory hyperpigmentation は、皮膚の炎症後に皮膚の色素が増加することを特徴とする皮膚の状態です。 postinflammatory hyperpigmentation は、長時間の日光曝露、炎症、または座瘡に関連するものを含むその他の皮膚損傷によって引き起こされる可能性があります。肌の色が濃い人は、通常、過度の日光にさらされると色素沈着過剰になる傾向があります。

Postinflammatory hyperpigmentation (PIH) は、皮膚の炎症や怪我の後に起こる頻繁な皮膚の問題です。この症状は長期間続く傾向があり、肌の色が濃い人ではさらに悪化します (Fitzpatrick skin types III–VI) 。自然に改善することも多いですが、時間がかかるため、長期にわたる治療が必要になることもよくあります。さまざまな治療法を組み合わせることが最も効果的です。
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 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.
