对于不想晒黑晒老的人来说,防晒产品对于长波UVA的防护能力是非常重要的
然而这部分在目前的SPF或PA甚至PPD标示是完全看不出来
因此研究防晒成分有其必要
详情请见邱品齐医师的文章:
防晒品的防晒系数可信吗?
http://goo.gl/5vMAV7
这个时候也许会有人说:“但我擦了某某没防UVA的成分的防晒就是没有黑
啊!”造成晒不晒黑的原因有很多,有的人的肤质就是属于易晒伤不易晒黑
对于容易晒黑的人,好好的挑选防UVA的防晒就非常重要了,更何况晒不黑不代表没有被长波UVA晒老
不过针对长波UVA的防晒成分也不是有添加就有效,还要看添加的浓度和配方搭配,所以最常看到的疑问是:“请问这样子的浓度防晒力够吗?”
老实说没有经过科学的检测,没有人能保证其防晒力,最保险的方式就是从已检测的名单内挑选

但很多口碑良好的防晒品还不在这份名单内
所以我们就要学习看成分浓度来“推测”其合理的长波UVA防晒力
警告:本篇整理专注在防晒力,关于化学防晒成分的安全议题也相当重要,
请详见版上antioxidant写的“化学性防晒成分8大类”一文
以下是有效防御长波UVA的防晒成分:
Zinc Oxide (氧化锌) 290nm-400nm(380nm) 卫生署 2.0-20.0%
Butyl Methoxydibenzoylmethane (Avobezone、Parsol 1789) 320nm-400nm 卫生署上限 5.0%
Methylene Bis-benzotriazolyl Tetramethylbutylphenol (Tinosorb M) 280nm-400nm 卫生署上限 10%
Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S) 280nm-400nm 卫生署上限 10%
Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus) 320nm-400nm 卫生署上限 10%
Terephthalylidene Dicamphor Sulfonic Acid (Mexoryl SX) 290nm-400nm 卫生署上限 10%

上图列出了各种防晒剂的紫外线穿透图
大家可以对照一下,了解各个成分的防御波长和强度
横轴是紫外线波长,纵轴是消光系数,曲线越高代表在该波长的防护效果越好,可以注意
到大部分的成分在370nm以后开始骤减,其中Avobenvoze和Tinosorb M可以维持较好的防
护力,不过Avobenzone在经过10 MED最低致红剂量的照射后防护力会骤减,所以需要搭配
光稳定剂,Tinosorb M虽然在370nm以上表现很杰出,但290nm-370nm的波段却不如Tinoso
rb S,所以没有一个单一成分是完美的,彼此搭配互补才能达到最好的防护力
Avobenzone = BMBM (S66)
Tinosorb M = MBBT (S79)
Tinosorb S = BEMT (S81)
Uvinul A Plus = DHHB (S89)
Mexoryl SX = TDSA (S71)
但是这些成分到底要添加多少才有足够的长波UVA防晒力呢?
就目前手边可以观察的资料就是邱品齐医师的检测报告,我找出了该报告大部分的化学性防晒成分浓度
(物理性的我家附近药妆店找不太到,若知道详细浓度的版友可以提供)
大家可以对应一下该产品的测试结果,进而来产生一定的概念
不过在看整理之前,我们要来了解一下邱品齐医师检测报告所采用的标准
Boots Star Rating ★星级标示
UVA的防护效能标示之一,为体外(非人体)测试法,以人工薄膜比较有涂抹防晒剂与没
防晒剂紫外线穿透率,测定出防晒剂防UVA的效能,由英国Boots公司提出,计算方式为紫
外线UVA及紫外线UVB的比值(UVA/UVB Ratio),若比值越接近1,获得的★星号越高,此
一标准代表的是防晒品防御能力的“平均度”
临界波长 (Critical wavelength)
将防晒品涂在薄膜上,再以紫外线扫描照射290nm-400nm波段,当防晒品吸光值面积达到紫外线全波段总吸光值面积90%时,所对应的波长即称为临界波长。举例来说,若测试产品的临界波长为381nm,代表防晒产品可以阻绝波长381nm以下的紫外线达90%,数字越靠近400nm代表防护的波长越广。美国皮肤科医学会提出要在美国的防晒产品上标示‘Broad Spectrum’需要符合两个条件:SPF需在15以上且临界波长要在370nm以上。此依标准代表的是防晒品防御能力的“广度”
搞懂了这两种标示后,就先别急着把手上检测只有一颗星或两颗星的防晒品丢掉,因为星
号是指“平均度”,大家在意会不会晒黑晒老的其实更要看临界波长的防晒“广度”,若
防晒产品的星号只有三颗星甚至两颗星,但是临界波长高达380nm,那有可能只是因为它
的UVB比重相对较多,导致比值较低,不代表长波UVA的防御能力一定弱,两种标示搭配看会较准确
PS.当然最好的情况是拿到各个防晒产品的紫外线穿透图,并且用叠图的方式,这样谁强谁弱一目了然,只是一般消费者很难看到这方面的资料

看完这些整理以后,我个人归纳出以下几点:
1.防晒成分与足够的浓度只是防晒力的必要条件,并非充分条件
2.浓度太低要有足够的保护力也很难
3.不同成分所需要的浓度不太相同,像Avobenzone只需要3%就可以有不错的防护效果
4.临界波长要达到380nm以上,最好同时有Avobenzone与Tinosorb M
5.不同系统(美式配方PARSOL 1789、莱雅式配方Mexoryl、Tinosorb家族))之间的混搭
应该是未来趋势
