摘要

雀斑，是一種臉上常見的色素斑，有家族遺傳性，顏色會隨日曬而加重，且好發在日光曝曬的部位。利用Q開關波長532nm的釹雅各雷射、紫翠玉雷射、或紅寶石雷射已經能完全、而且快速地治療雀斑。亞洲人的皮膚類型多半是第三型以上，以第四、五型為最多。雷射關於誕一方面的治療最大的考量，就是術後色素的變化，即術後色素缺失、或炎症後色素沈芺的現象。我譬嘗試以波長550至590nm的過濾器，能量密度25至35 J/cm2,單一脈衝，脈衝寬4.0 msec的脈光治療亞洲人臉上的雀斑；並利用臨床皮膚科醫師、病人自身滿意度、彩色照片、黑白照片、和紫外光偵測相機與照片，來評估脈衝光治療雀斑的臨床效果。結果顯示，臨床的評估有75%的病人達到”卓越”和”良好”的改善程度；而病人自身的評估，病人滿意程度在很滿意以上約佔87.5%。結論是，脈衝光不失為一種快速、安全、副作用少、滿高又有效的方式，用來治療亞洲人臉上雀斑。

Freckles or ephelides are cutaneous pigmented lesions that have familial inheritance, increase
degree of pigmentation by sun-exposure, and frequently seen on face and other sun-exposure areas.
Freckles (ephelides) have been reported to respond completely and quickly to the Q-switched 532nm
Nd:YAG, alexandrite or ruby lasers. The skin types of Asian patients are above type III, and mostly
are type IV or V. The most important consideration for laser therapy on Asian skin is post-therapy
hypo-pigmentation or post-inflammatory hyper-pigmentation. We try to treat facial freckles of Asian
patients with intense pulsed light and with the following parameters: cut-off filters of 550-590nm,
fluences of 25-35 J/cm2,single pulse, and pulse width of 4.0 msec. The response results are evaluat-
ed by dermatologist, patients themselves, color photography, ultraviolet detect camera and ultraviolet
photography. The results reveal: in clinical evaluation, about 75% patients had “excellent” or “good”
results. About 87.5% patients had “Extremely” or “very” satisfied in patient-self evaluation. In con-
clusion, facial freckles of Asian skin treated with intense pulsed light is a quick, safe, satisfied, and
effective method with little side effects.
