Abstract: 点阵CO2激光作为一种基于选择性光热作用的微创治疗技术，近年来在多模态治疗领域展现出显著优势。其通过诱导微热损伤区(MTZ)激活组织修复、增强局部药物渗透和调节免疫微环境，在瘢痕重塑、色素病变、脱发、白癜风及私密医学等多个适应症中拓展了临床应用边界。联合微针射频、脉冲染料激光、PRP、生长因子及局部药物治疗，不仅可提升疗效，还能缩短恢复周期，尤其适用于顽固性病灶。在机制层面，点阵CO2激光可促进胶原新生、改善皮肤屏障功能、上调claudin-1并抑制TGF-β1、IL-6等炎性因子表达，具有良好的组织再生潜力，其形成的微通道也为药物透皮吸收提供了理想路径。随着双波长系统、Er:YAG-CO2混合激光、图像导航及AI参数调控等新兴技术的应用，其治疗精准度和安全性进一步提升，结合生物标志物监测有望实现个体化干预。总体而言，点阵CO2激光作为多模态治疗平台，已在多个复杂性皮肤与黏膜疾病的管理中展现出良好的疗效、安全性与可持续性，未来研究应重点关注点阵CO2激光在“病灶分型–参数匹配–组合优化”路径下的精确应用，同时，可联合生物标志物、AI参数调控与智能递药系统，建立推广性强、可连续复制的个体化干预模式，从而达到提高疗效，增强临床指导价值的目的。As a minimally invasive technology based on the principle of selective photothermolysis, fractional CO2 laser has demonstrated remarkable advantages in the field of multimodal therapy in recent years. By inducing microscopic thermal zones (MTZs), it activates tissue repair, enhances local drug penetration, and modulates the immune microenvironment, thereby expanding its clinical applications in scar remodeling, pigmentary disorders, alopecia, vitiligo, and aesthetic gynecology. When combined with microneedle radiofrequency, pulsed dye laser, platelet-rich plasma (PRP), growth factors, and topical medications, fractional CO2 laser not only improves therapeutic outcomes but also shortens the recovery period, especially for recalcitrant lesions. Mechanistically, the fractional CO2 laser promotes collagen neogenesis, improves skin barrier function, upregulates claudin-1, and inhibits pro-inflammatory cytokines such as TGF-β1 and IL-6, demonstrating strong potential for tissue regeneration. The microchannels it creates offer an ideal pathway for transdermal drug delivery. With the integration of emerging technologies such as dual-wavelength systems, Er:YAG-CO2 hybrid lasers, image-guided navigation, and AI-based parameter optimization, both precision and safety have been further enhanced. The incorporation of biomarker monitoring holds promise for personalized treatment strategies. Overall, as a versatile platform for multimodal therapy, fractional CO2 laser has shown excellent efficacy, safety, and sustainability in managing a wide range of complex cutaneous and mucosal disorders. Future research should focus on its precise application under the framework of “lesion classification-parameter matching-combination optimization”. Furthermore, integrating biomarkers, AI-controlled protocols, and intelligent drug delivery systems may help establish replicable, scalable, and personalized intervention models, ultimately improving efficacy and clinical decision-making.
