Abstract

INTRODUCTION: It has been well established that patients with darker skin types (Fitzpatrick skin types IV-VI) have an increased incidence of thermal induced side effects from laser and radio frequency (RF) treatments. Complications include a higher risk of post-inflammatory hyperpigmentation, hypopigmentation, and scarring, leading to unsatisfactory clinical outcomes. Fractional technologies improve the safety when treating patients with skin of color by treating only fractions of the skin while leaving a healing reservoir of untreated skin that improves the healing process. Fractional RF tips with coated pins may offer a more advantageous safety profile, particularly in the skin-of-color population (Fitzpatrick skin types IV-VI) by increasing the protection of the epidermal layer by minimizing epidermal heating The current study was intended to evaluate the safety and efficacy of fractional RF technology for the treatment of patients with Fitzpatrick skin type VI. METHODS: 35 subjects with skin type VI received 3 sessions of facial treatments, 4 weeks apart using a fractional RF device with 24 pin coated tip. The treatment's safety and efficacy were evaluated at 2 follow-up visits, 6 and 12 weeks after the last treatment. RESULTS: Skin characteristics evaluations, including Fitzpatrick Wrinkles Classification, acne scars, and overall facial appearance demonstrated improvement in follow-up visits comparing to baseline. No significant unexpected adverse events were detected. CONCLUSION: The current study proves the safety and efficacy of the fractional RF treatment modality with coated pins tips for skin rejuvenation treatments resulting in improved wrinkles, acne scars, and overall skin appearance, in patients with skin type VI.

摘要

引言:众所周知,肤色较深的患者(菲茨帕特里克皮肤分型IV - VI型)在接受激光和射频(RF)治疗时,热诱导副作用的发生率会增加。并发症包括炎症后色素沉着、色素减退和瘢痕形成的风险更高,导致临床效果不理想。分次治疗技术通过仅治疗部分皮肤,同时保留未治疗皮肤的愈合储备来改善愈合过程,从而提高了治疗有色人种皮肤患者时的安全性。带有涂层针的分次射频尖端可能提供更有利的安全概况,特别是在有色人种皮肤人群(菲茨帕特里克皮肤分型IV - VI型)中,通过最小化表皮加热来增加对表皮层的保护。本研究旨在评估分次射频技术治疗菲茨帕特里克VI型皮肤患者的安全性和有效性。方法:35名VI型皮肤受试者接受了3次面部治疗,每次治疗间隔4周,使用带有24针涂层尖端的分次射频设备。在最后一次治疗后的6周和12周的2次随访中评估治疗的安全性和有效性。结果:与基线相比,包括菲茨帕特里克皱纹分类、痤疮瘢痕和整体面部外观在内的皮肤特征评估在随访中显示出改善。未检测到明显的意外不良事件。结论:本研究证明了带有涂层针尖端的分次射频治疗方式用于皮肤年轻化治疗的安全性和有效性,可改善VI型皮肤患者的皱纹、痤疮瘢痕和整体皮肤外观。《药物皮肤病学杂志》。2018;17(
