Post-acne erythema is described as erythema due to release of inflammatory cytokines, dilatation of microcapillaries within papillary dermis and thinning of epidermis. The erythema usually fades; however, it can persist for months.
In this review, we decided to evaluate efficacy of light and laser treatments in acne-induced erythema.
We searched PUBMED, Embase, Cochrane, and Google Scholar for relevant key words. Inclusion criteria were randomized clinical trials (RCTs) that evaluated efficacy of laser or light in PAE until September 2021.
Twelve RCTs were selected for the final assessment. Light and laser treatments included pulsed dye laser (PDL), intense pulsed light (IPL), Q-switched neodymium-doped yttrium aluminum garnet (QS Nd:YAG), fractional photothermolysis, alexandrite, solid-slate 589-1319 nm, and pro-yellow laser.
Light and laser treatments are effective treatment modalities in reduction of acne-induced erythema along with active acne lesions and atrophic acne scars.
痤疮后红斑被描述为由于炎症细胞因子释放、真皮乳头层微血管扩张和表皮变薄引起的红斑。红斑通常会消退；然而，它可能会持续数月。
在这篇综述中，我们决定评估光和激光治疗在痤疮性红斑中的疗效。
我们在 PUBMED、Embase、Cochrane 和 Google Scholar 上搜索了相关的关键词。纳入标准为评价激光或光在 PAE 中疗效的随机临床试验（RCTs），直到 2021 年 9 月。
最终评估选择了 12 项 RCT。光和激光治疗包括脉冲染料激光（PDL）、强脉冲光（IPL）、Q 开关掺钕钇铝石榴石（QS Nd:YAG）、点阵式光热分解、亚历山大石、固体板 589-1319nm 和 pro-yellow 激光。
光和激光治疗是减少痤疮性红斑以及活动性痤疮病变和萎缩性痤疮瘢痕的有效治疗方法。
