向有害防曬說“不” / Say "no" to harmful sunscreen


慎選防曬品 / Sunscreen tips

市面上有很多防曬品,大家購買時要小心選擇,因為不論平或貴均有劣品。最近TOPick就委託香港一間生物科技公司對24款防曬產品進行檢測,有7款未能達標。大家可按連結了解更多報告內容。

今次檢測中的類雌激素測試,當中有兩個樣本每克類雌激素的含量超出一粒避孕丸。而類雌激素已被世衛列為一級致癌物。依據世衞標準,每人每日每公斤體重不應吸收超過 50 納克的雌激素, 50 公斤的女生就不應吸收超過2,500 納克類雌激素,超標吸入可引發癌症,有可能干擾內分泌系統,破壞生理平衡,亦有機會造成癡肥、加速早熟,女性更可能出現月經紊亂。

大家購買防曬 (甚至其他護膚品)時可留意一下有沒有以下含類雌激素的成分*:

1. 防止外線成分

- 甲氧基肉桂酸乙基己酯

- 丁基甲氧基二苯甲酰基甲烷

- 二苯酮-1 (BP-1), BP-2, BP-3, BP-4

- 甲基水楊醇

- 甲氧基肉桂酸辛酯

- 4-甲基亞芐基樟腦

2. 防腐劑

- 羥苯甲酯

- 及羥苯丙酯

- 及其他有「對羥基苯甲酸(Paraben)」字眼的成分

We should all pay attention when choosing sunscreen because there are many inferior sunscreens on the market regardless of the price. Recently TOPick engaged a HK biotech co. to test 24 sunscreen products, but 7 failed to meet the standard. Please check the link at the bottom for more detail of the report.

In the estrogen-like test, two samples were found to contain high concentrations of estrogen - estrogen per gram is more than the content in a contraceptive pill. The WTO already listed estrogen as Group 1 carcinogen.

According to WHO standard, each person should not absorb more than 50 nanograms of estrogen per kilogram of body weight per day. Excessive absorption can cause cancer. It may interfere the endocrine system and disrupt the physiological balance if one frequently expose to estrogen. It may also cause obesity and accelerate precocious puberty. Menstrual disorders may also occur.

When buying sunscreen (in fact some skincare products as well), check if the following ingredients*, which contain estrogen-like ingredient, are present:

1. Common ingredients to prevent UV rays

- Ethylhexyl methoxycinnamate

- Butylmethoxydibenzoylmethane

- Benzophenone-1 (BP-1), BP-2, BP-3, BP-4

- Homosalate

- Octinoxate

- 4-Methylbenzylidene camphor (4-MBC)

2. Preservative

- Methylparaben

- Propylparaben

- Other ingredients with the word “paraben”
