Sunscreen, also known as sunblock, sun lotion or sun cream, is a photoprotective topical product for the skin that helps protect against sunburn and prevent skin cancer. Sunscreens come as lotions, sprays, gels, foams (such as an expanded foam lotion or whipped lotion), sticks, powders and other topical products.

防晒霜(英語:sunscreen)是防止皮膚受紫外線曬傷的護膚品。有不同的防御指数SPF(Sun Protection Factor),指在一段情況下可延長避免晒傷的時間。如用SPF4太陽油,則在每平方公分的皮膚塗抹有2毫克防曬乳的情況下,可以延長4倍的曬傷時間,本來一小時便會晒傷的皮膚,可以受保護多至4小時;亦能夠阻隔 75%的UVB (算法: (SPF-1)/SPF)。防曬黑係數(protection factor for UVA)則為評估防曬劑對UVA的防曬能力指數,包含日本的PA值系統、歐洲的PPD值系統。亦有醫學報告指出,防晒霜一般不能夠完全隔掉紫外線,紫外線還是可以繼續穿透這層防曬產品。因此最好先用抗氧化產品,以中和自由基,同時幫助膠原蛋白生成。使用防曬霜等防曬產品是讓皮膚免受紫外線損害的有效方法之一,但防曬霜只是一個有助於減少紫外線照射的方法,並不能完全阻擋所有的紫外線。因此,即使擦了防曬霜亦不應該長時間暴露在陽光下,仍然應該盡量處於陰涼處,同時穿著好防護衣物。
