 Consumers believe that sunscreen with higher SPFsmean more protection, while some doctors say the numbers are a marketing 1 ploy 2.


     买防晒霜SPF值不是越高越好,防晒指数勿高于30。一般防晒产品都标有SPF数值,促销小姐会告诉你这个值越高,防晒效果越强。在美国,市场上居然出现了SPF高达110的防晒霜。然而,超高的SPF值只是商家的营销骗局。


  防晒品,SPF数值是一个重要指标。SPF表示防晒品所能发挥的防晒效能的高低,是根据皮肤的最低红斑剂量确定的。假如皮肤的最低红斑剂量是15分钟,那么使用SPF为10的防晒霜,理论上可在阳光下逗留10倍时间即150分钟,皮肤才会出现微红。不过SPF数值越大,防晒的化学物质就越多,有的化学成分长期大量使用,会损伤皮肤,甚至导致皮肤癌等。
