Scars sustained following injury in patients with darker skin types can present a treatment challenge. These scars often hyperpigment and may remain refractory to first line treatments such as topical retinoids and hydroquinone. Additionally, more aggressive treatment interventions such as ablative resurfacing, chemical peels, and Q-switched laser therapy may actually worsen the pigmentation. We describe a 22-year female with a hyperpigmented scar and Fitzpatrick type IV skin that improved markedly following treatment with a fractionated erbium doped fiber laser. The improvement was maintained at least 1 year following the last procedure.
肤色较深的患者受伤后留下的疤痕可能带来治疗挑战。这些疤痕常常会出现色素沉着，对于诸如外用维甲酸和氢醌等一线治疗可能仍无反应。此外，诸如剥脱性皮肤磨削术、化学剥脱术和调Q激光治疗等更激进的治疗干预实际上可能会使色素沉着恶化。我们描述了一名22岁女性，她有一处色素沉着疤痕且皮肤属于 Fitzpatrick IV型，在接受分次掺铒光纤激光治疗后有明显改善。最后一次治疗后，改善情况至少维持了1年。
