　　——皮肤晒伤紧急护理

　　晒后1~3小时：毛细血管扩张，出现红、热、刺痛等皮肤灼伤反应，可用常温纯净水、补水保湿喷雾进行湿敷。

　　晒后3~6小时：皮肤处于缺水状态，敷一张补水面膜或舒缓面膜，给皮肤补水。

　　晒后1~2天：晒伤的皮肤细胞开始脱落，补水保湿后使用修复屏障的护肤品，加入舒缓修复屏障的护肤品。

　　晒后3天以上：皮肤屏障修复的同时，为了避免过度的黑素沉积，可选择修复美白类护肤品。

　　晒后7天以上：皮肤暴露部位出现明显的黑素沉积，此时应做好清洁、补水、保湿和舒缓皮肤，缓慢促使皮肤黑素沉积淡化。

　　脱皮：千万勿撕剥。外涂低敏保湿乳有助于损伤表皮的新生。尽量穿宽松衣服减少摩擦。

　　水疱：尽量保持小水疱疱壁的完整。较大的水疱可用无菌注射器抽吸出疱液，并用无菌纱布覆盖、包扎。已破溃的水疱可用无菌生理盐水湿敷或外敷莫匹罗星盐水纱条，并进行简单包扎。注意，一旦发现水疱疱液浑浊，或局部红、肿、痛等感染迹象，应尽早就医。
