Acne is very common skin condition. Most patients with acne will have a degree of scarring as a result of their acne. In patients with darker skin color the scarring can be further complicated by hyperpigmentation. Several treatment options can be used to improve acne scarring, however the problem of post acne hyperpigmentation is not often addressed. This study especially focus on the treatment of pigmented post acne scarring using skin microneedling.
The primary objective is to assess the improvement of pigmentation of acne scarring in patients with dark skin using microneedling. Secondary objectives include evaluation of post acne scarring improvement and the safety of microneedling in pigmented skin.
MATERIALS & METHODS: 39 Patients with darker skin colors (types 3, 4 and 5) completed study. Baseline evaluation for both acne scars and pigmentation scores performed using "post acne hyperpigmentation index" (PAHPI) and Goodman-Baron scales (GB scale). Microneedling treatment done and subsequently patients reviewed at 2 weeks for initial assessment and then after at least 4 weeks from date of initial assessment using same scoring methods for both scars and pigmentation. Baseline photographs were taken and again at final assessment.
Both PAHPI and Goodman-Baron scales showed statistically significant improvement from baseline following microneedling treatment. Side effects were minor and of transient nature. None of our patients showed worsening of pigmentation.
Microneedling is an effective treatment for both acne scars and associated pigmentation in patients with dark skin color. The treatment appears to be safe apart from transient redness, mild dryness, and small hematomas, however additional treatments may be needed in some patients to achieve more improvement in pigmentation.
痤疮是一种非常常见的皮肤疾病。大多数痤疮患者会因痤疮而出现一定程度的瘢痕。对于肤色较深的患者，瘢痕会因色素沉着而进一步复杂化。有几种治疗方法可用于改善痤疮瘢痕，但痤疮后色素沉着问题往往未得到解决。本研究特别关注使用皮肤微针治疗痤疮后色素沉着瘢痕。
主要目的是评估使用微针治疗对深色皮肤患者痤疮瘢痕色素沉着的改善情况。次要目的包括评估痤疮后瘢痕的改善情况以及微针在色素沉着皮肤中的安全性。
39名肤色较深（3型、4型和5型）的患者完成了研究。使用“痤疮后色素沉着指数”（PAHPI）和古德曼-巴伦量表（GB量表）对痤疮瘢痕和色素沉着评分进行基线评估。进行微针治疗，随后在2周时对患者进行初步评估，然后在初次评估日期至少4周后，使用相同的评分方法对瘢痕和色素沉着进行评估。拍摄基线照片，并在最终评估时再次拍摄。
微针治疗后，PAHPI和古德曼-巴伦量表均显示与基线相比有统计学意义的改善。副作用较小且为短暂性。我们的患者均未出现色素沉着加重的情况。
微针是治疗深色皮肤患者痤疮瘢痕及相关色素沉着的有效方法。除了短暂的发红、轻度干燥和小血肿外，该治疗似乎是安全的，然而，一些患者可能需要额外的治疗以在色素沉着方面取得更大改善。
