如何选择防晒霜

The American Melanoma Foundation recommends that everyone wear sunscreen daily to get the best protection against the sun's damaging ultraviolet rays--particularly on the face, neck and hands, which receive the most sun exposure. To get the most benefit from your sunscreen, it is important that you choose a sunscreen that is the right type for your activity and skin type.

根据美国黑色素瘤基金会的建议，为了最好的保护皮肤防受阳光紫外线的伤害，我们应该每天都对皮肤进行防晒保护，而这其中，脸部，颈部和手部这些接收到最大阳光照射的部位尤其应该予以重视。防晒霜（油）选择的正确与否则决定了皮肤是否能最大程度的利用防晒油的防晒功能，而要正确选择合适的防晒油，则必须兼顾皮肤性质和活动内容。

Instructions选择小窍门

1. Look for broad-spectrum sunscreens with at least an SPF 15. Broad-spectrum formulas block both UV-A and UV-B rays and offer the highest level of protection from the sun's ultraviolet rays. UVB radiation are the rays that cause sunburn and contribute to skin cancer, while UVA rays absorb deeply into the skin and cause wrinkles and premature aging. The SPF factor refers only to the sunscreens UVB protection--not its UVA protection.

选择SPF值15以上的全效防晒油，全效防晒配方可以有效的阻挡住UV-A和UV-B射线，因而为皮肤提供最高程度的防紫外线保护。UV-B射线是导致皮肤晒伤和皮肤癌的有害射线，而UV-A则会进入譬如深层，导致皱纹和过早的衰老。而防晒霜的SPF数值表示的则是该种产品对UV-B的防护能力，而非其对UV-A的防护能力。

        

2. Choose a waterproof sunscreen if you will be swimming or participating in activities that will cause you to sweat. Although the waterproof formulas will keep your skin protected longer, you will need to reapply it after excessive sweating or a long swim.

在进行游泳或者其他容易大量出汗的户外活动室，选择防水性的防晒霜。同时，虽然防水型的产品能够更长时间的保护你的皮肤，但你仍需在大量出汗和长时间游泳后补充产品的用量。

3. Consider your skin type when choosing a sunscreen. Sunscreen formulas are available for both sensitive and oily skin types to help prevent clogged pores and skin reactions in highly sensitive people.

选择防晒油时需要考虑个人的皮肤类型。对于敏感性肌肤和油性肌肤的人，在选择时应注意特定的防晒油组分，以防止皮肤毛孔的堵塞和皮肤的敏感反应。
