Acne scars carry a huge physical and psychological impact on people. This article aims to evaluate the role of fractional radiotherapy in treatment of atrophic acne scars. The main objective includes providing an up-to-date review of existing literature, presenting the most significant studies conducted in this field.
In order to study the impact of fractional radiotherapy on the appearance of atrophic acne scars, we conducted a search on Pubmed using the keywords "fractional radiotherapy", combined with/or "acne", "atrophic acne scars" and "acne scars" and found 75 papers, from which we selected 39.
There are several therapeutic approaches for the improvement of acne scars with variable results and possible side effects. Fractional radiofrequency system has been used widely in the last years, as it turned out to be an effective treatment method, either in combination with other modalities, or alone.
There are no generalized clinical guidelines adopted to standardize atrophic acne scar treatment. The multiple therapeutic options available create a dilemma in choosing the proper method in order to enhance its efficacy and to minimize its risks. The accumulated experience in nonablative collagen stimulating devices like fractional radiofrequency has proven that thickening of interstitial fibers in the dermis is possible with a controlled thermal injury, without epidermal damage and development of side effects.
痤疮瘢痕对人们的身体和心理造成巨大影响。本文旨在评估分次放射治疗在萎缩性痤疮瘢痕治疗中的作用。主要目的包括对现有文献进行最新综述，介绍该领域进行的最重要研究。
为研究分次放射治疗对萎缩性痤疮瘢痕外观的影响，我们在PubMed上使用关键词“分次放射治疗”，结合/或“痤疮”“萎缩性痤疮瘢痕”和“痤疮瘢痕”进行搜索，共找到75篇论文，从中选取了39篇。
改善痤疮瘢痕有多种治疗方法，效果各异且可能有副作用。近年来，分次射频系统已被广泛应用，因为它已被证明是一种有效的治疗方法，可与其他方式联合使用，也可单独使用。
目前尚无用于规范萎缩性痤疮瘢痕治疗的通用临床指南。现有的多种治疗选择在选择合适方法以提高疗效并将风险降至最低时造成了两难局面。在诸如分次射频等非剥脱性胶原刺激设备方面积累的经验已证明，通过可控的热损伤可使真皮间质纤维增厚，而不会造成表皮损伤和产生副作用。
