style="font-family:微软雅黑;">你是不是也以为仅爱美的人才需要做好防晒呢?其实,由国内外的研究发现,紫外线照射愈多,则产生皮肤癌的机会增加(包含基底细胞瘤,黑色素细胞癌)。另外,紫外线还会造成皮肤的真皮层变性,使皮肤松弛,产生皱纹,加速皮肤老化。有些人脸上若有痤疮,雀斑,黑斑,或颧骨斑,则紫外线会使这些皮肤问题恶化。所以,为了永保肌肤年轻健康,防晒应该成为人人每天必作的重要功课!很多爱美的女性同胞买了各式各样的保养品来保养肌肤,却常常忽略了防晒才是停止皮肤老化巨轮转动的钥匙 !!</span><br /> <br /> <span style="font-family:微软雅黑;">什么时候需要防晒</span><br /> <br /> <span style="font-family:微软雅黑;">无论是男性、女性、大朋友、小朋友,除了在室外活动需要防晒外,最容易被忽略的是开车坐车,或在室内活动时的防晒任务。其实,紫外线包含 UVA 光及 UVB 光,虽然云层及玻璃可挡住 UVB 光,但是 UVA 光则可以穿透,所以即使在室内任务,若坐在未装上窗帘的窗户边,仍需要作防晒。</span><br /> <br /> <span style="font-family:微软雅黑;">如何防晒</span><br /> <br /> <span style="font-family:微软雅黑;">防晒工作包含涂抹防晒油及最常被忽略的物理性防晒(如戴上帽子,穿长袖衣物,撑阳伞)。至于如何选择防晒产品,需注意以下事项:</span><br /> <br /> <span style="font-family:微软雅黑;">• 选择适合自己肤质的防晒产品:容易长痤疮的人,可选用不具致粉刺性的防晒产品,小朋友或皮肤敏感的人,可选择不含容易造成过敏的成分(如 PABA )的防晒产品。</span><br /> <br /> <span style="font-family:微软雅黑;">• 防晒产品需清楚标记可同时预防 UVA 光及 UVB 光:防 UVB 光的防晒系数标记为 SPF, 是指涂抹了防晒油后,被 UVB 光晒红需要的时间,和未涂抹防晒油之前晒红所需时间的比值,防晒系数愈高则防晒效果愈佳。防 UVA 光的防晒系数标记为 PA (日系商品)或 PPD ( 欧洲产品 ) 。</span><br /> <br /> <span style="font-family:微软雅黑;">• 选择适适当防晒系数的产品:若是常规日常保养,可选用 SPF 20-25 的产品,至于到海边或长时间在户外活动,则可使用 SPF30 以上的防晒油。防 UVA 光的防晒系数则最好是在 PA++ ~ PA+++ 或 PPD 至少 4 以上,才能达到良好的防晒效果。</span><br /> <br /> <span style="font-family:微软雅黑;">如何正确涂抹防晒产品</span><br /> <br /> <span style="font-family:微软雅黑;">根据研究发现,涂抹防晒产品的量需达到每平方厘米 2 毫克( 2mg/cm 2 )才可以达到防晒产品上所标记的保护效果。常规人因为没有涂抹足够量的防晒产品,导致防晒效果大打折扣。为避免这种情况发生,美国皮肤科医学会杂志建议,在接触阳光前 15-30 分钟涂抹第一次的防晒油,接着在接触阳光后 15-30 分钟后涂抹第二次防晒油,这样的防晒效果比起常规认为的每 2 到 3 小时补涂一次防晒产品的效果还好。不过,若是有从事水上活动或大量流汗的运动,则应该在活动后补擦防晒产品,以确保防晒效果。</span><br /> <br /> <span style="font-family:微软雅黑;">结语</span><br /> <br /> <span style="font-family:微软雅黑;">紫外线对人体的影响大都是缓慢累积而成的,所以很容易受到常规人的忽略,再加上很多人有多晒太阳对健康有益的迷思,因此,不重视防晒任务的必要性。其实,在了解紫外线对人体的影响之后,您应该知道:想拥有健康美丽的皮肤,防晒工作绝对是您的最佳保养利器。</span></span><span
