澳大利亚皮肤癌专家警告说,不当使用防晒霜,例如施用太少,不每两个小时重新施用,或将其储存在热中,即使贴有正确标签的产品,也能减少保护。 Australian skin cancer experts warn that improper sunscreen use—such as applying too little, not reapplying every two hours, or storing it in heat—can reduce protection, even with correctly labeled products. 他们建议每身体部位使用大约一个茶匙,在太阳照射前20分钟使用,在汗水、游泳或摩擦后再施用。 They recommend using about one teaspoon per body part, applying 20 minutes before sun exposure, and reapplying after sweating, swimming, or rubbing. 当紫外线水平超过3时,应使用日光屏,并与防护服、帽子和遮罩相结合。 Sunscreen should be used when UV levels exceed 3, and combined with protective clothing, hats, and shade. 一些防晒霜最近未能通过测试并被召回,突出了适当使用和储存的重要性。 Some sunscreens have recently failed tests and been recalled, highlighting the importance of proper use and storage.
