• intros：{"brand_intro":"LightStim源自美国，是全球最早专注于LED光疗美容的品牌之一，成立于2001年。创始人Dr. David J. Goldberg是皮肤科专家，品牌核心优势在于其专利\"多波长LED阵列\"技术，产品通过FDA 510(k)认证，被美国皮肤科学会推荐。LightStim坚持\"无创、无痛、无药物\"理念，所有产品均在美国家庭医生诊所和皮肤科广泛使用。其蓝光祛痘仪是欧美市场销量冠军，以高性价比和临床验证效果著称。","product_intro":"LightStim for Acne是一款纯蓝光祛痘仪，采用415nm+470nm双波段蓝光，覆盖杀菌和抗炎双重作用。产品定位为\"专业级家用光疗仪\"，无需凝胶，直接照射即可。适用场景包括轻度至中度痤疮、粉刺、毛囊炎。相比雅萌，LightStim功能更专注，价格更低，且无需耗材；但缺少射频功能，无法修复痘坑。其优势在于操作简单、安全性高，适合光疗入门用户。","key_specs":{"光波长":"415nm+470nm双波段蓝光","灯珠数量":"72颗LED灯珠，覆盖面积大","能量密度":"40mW/cm²，符合FDA标准","适用肤质":"油性、痘痘肌、敏感肌可用","使用频率":"每日1次，每次3分钟","电源方式":"插电式，持续使用"}}
