一年四季中,冬季阳光的紫外线含量最低,到春天来临时紫外线含量骤然升高,而且由于春季气候干燥,紫外线穿透性强,到达地面的量也多,人们一下子难以适应,极易晒黑。

一年四季中,冬季阳光的紫外线含量最低,到春天来临时紫外线含量骤然升高,而且由于春季气候干燥,紫外线穿透性强,到达地面的量也多,人们一下子难以适应,极易晒黑。
In the four seasons of the year, the ultraviolet rays of the sunlight in winter are the lowest, and the UV content rises abruptly when the spring is coming, and because of the dry weather in spring, the ultraviolet penetration is strong and the amount of reaching the ground is much more, people are difficult to adapt to the sun and are easily tanned.
晒斑经过28天的新陈代谢周期,便会留下紫外线“亲吻”肌肤所留下的印记。所以很多女性以为入夏长出来的斑其实在春天就有了受伤的痕迹。
After 28 days of metabolic cycle, sunburn will leave the impression of "kissing" the skin. So many women thought that the spots that came out in summer actually had signs of injury in spring.
同时,春天又是外出踏青旅游的旺季,如不注意防晒,会加重或诱发皮炎。所以对女性而言,在春季更应该特别注意防晒。
At the same time, spring is also the peak season for outing outing. If you don't pay attention to sunscreen, it will aggravate or induce dermatitis. Therefore, for women, in spring, special attention should be paid to sunscreen.
市场上炒得纷纷扬扬的各种防晒霜,使不少人心神不定,很多人因为缺乏充分了解而拿不定主意是用还是不用,弄不清哪个品牌好。
A variety of sunscreen saute in the market has made a lot of people unsure. Many people can't make up their minds because they lack sufficient understanding and do not know which brand is good.
如何做出正确的选择,科学的答案是,不同型号的防晒霜对不同类型的紫外线照射具有不同的拮抗作用,既不能随便滥用,也不能过于迷信。
How to make the right choice, the scientific answer is that different types of sunscreen have different antagonistic effects on different types of ultraviolet radiation, neither abusive nor superstitious.
防晒霜,严格点说应叫“遮光剂”。不管是价值惊人的洋品牌,还是价值稍逊的国产品牌,防晒霜基本成分均为二氧化钛、氧化锌、炉甘石、对氨苯甲酸、苯酚类衍生物、水杨酸及鞣酸类化合物。
Sunscreen, strictly speaking, should be called "shading". The basic components of sunscreen are titanium dioxide, Zinc Oxide, calamine, benzoic acid, phenol derivatives, salicylic acid and tannic compounds, whether it is an amazing foreign brand or a slightly inferior domestic brand.
按照人们对防晒时间、强度的不同需要,目前市售的防晒霜分为6~40不等的档次,被称为“防晒指数”。防晒产品包装上都会用英文字母和阿拉伯数字SPF-X表示(SPF是防晒系数SunProtectionFactor的缩写,X代表6~40等不同的档次)防晒指数。通常情况下,数字越大,防晒时间越长,但所含的物理或化学遮光剂成分也越多,对皮肤的刺激也越大。
According to people's different needs for sunscreen time and intensity, the sunscreen currently sold in the market is divided into 6~40 grades, which is called "sunscreen index". Sunscreen product packaging will be written in English letters and Arabia digital SPF-X (SPF is the abbreviation of the sun protection coefficient SunProtectionFactor, X represents 6~40 different grades) sunscreen index. Usually, the larger the number, the longer the time to screen, but the more physical or chemical sunscreens, the greater the skin irritation.
防晒产品的主要副作用是容易造成皮肤毛孔阻塞,影响汗液排泄,导致粉刺、暗疮等的发生。所以涂抹防晒产品后,要注意做好清洁。
The main side effects of sunscreen products are easy to cause skin pores blockage, affecting sweat excretion, resulting in acne, acne and so on. So after smearing sunscreen products, pay attention to cleaning.
但不能认为,防晒系数越大效果就越好。一般情况下使用防晒系数15~20的产品即可;如果长期在户外活动或外出旅游,可选用SPF-20以上的产品。
But it can not be considered that the bigger the sunscreen factor, the better the effect. Generally speaking, products with SPF 15~20 can be used. If you are in outdoor activities or traveling for a long time, you can use SPF-20 or more.

紫外线根据波长分为:近紫外线UV-A,远紫外线UV-B和超短紫外线UV-C。紫外线的波长愈短,对我们的皮肤危害越大。一项权威部门的测定称,目前市售的防晒霜对UV-A、UV-B两种波段的紫外线均具有确切的防护作用,对UV-B的效果优于UV-A,但是对UV-C基本无效。一些防晒广告中的宣传,存在着夸大其词的现象,不要轻信。
Ultraviolet light is divided into near ultraviolet UV-A, far ultraviolet UV-B and ultrashort ultraviolet UV-C according to wavelength.  The shorter the UV wavelength, the greater the harm to our skin. The determination of an authority department said that the current market sunscreen has the exact protective effect on the ultraviolet rays of the two bands of UV-A and UV-B, and the effect on UV-B is better than that of UV-A, but it is not effective for UV-C. There are exaggerations in the publicity of some sunscreen advertisements. Don't trust them.
除了防晒霜,遮阳伞、墨镜都有遮挡紫外线的效果,可根据需要,选择质量有保证的产品,提前做好准备。
In addition to sunscreen, sunshade and sunglasses have the effect of blocking ultraviolet rays. According to the needs, we can choose products with quality assurance and make preparations in advance.
