BP3是个危险指数较高的防晒剂,属于化学防晒剂。BP3可能诱发光过敏,且会被皮肤大量吸收,实验中90名6~8岁女童的尿液检测中有86名发现该物质,欧盟允许使用,要求用量不得超过6%。

不知道被皮肤大量吸收后会怎样?会不会对健康有影响?

保养品含有「二苯酮」(Benzophenone-BP)成份,这种成份可帮助对抗紫外线。不过美国最新研究发现,「二苯酮」会模拟女性雌激素作用,很可能增加女性罹患子宫内膜异位症风险。

"In some studies, researchers have found detectable levels of [oxybenzone] in human blood and breast milk. Based on animal studies, there’s concern that it could interfere with the normal function of a number of hormones, including estrogen....
...a paper recently published in the journal Reproductive Toxicology suggests that pregnant women who use sunscreen with oxybenzone daily might absorb enough of the chemical to increase the risk of a birth defect..."

"OXYBENZONE HAS A RANGE OF HIGHLY DAMAGING EFFECTS ON CORAL, FROM GROSS DEFORMITY TO DEATH, AND IS SHOWN TO BE AN ENDOCRINE DISRUPTER.

Baby coral exposed to field-realistic concentrations of oxybenzone encased themselves in their own skeleton and died.
One drop of oxybenzone in the equivalent of six-and-a-half Olympic-size swimming pools’ worth of water is sufficient to damage coral.
Levels of oxybenzone in seawater around coral reefs in Hawaii and the US Virgin Islands were found to be 12 times higher than the concentration that damages baby coral.
There are a number of concerns about the effect of oxybenzone on human health. It is on the EU’s ‘Substitute It Now’ list of substances that should be replaced and meets the criteria for ‘Substances of Very High Concern’. "

"Beginning January 1, 2021, Hawaii will ban the sale, offer of sale or distribution of any sunscreens containing oxybenzone or octinoxate without a prescription from a licensed health care provider"

Fast facts
Approved in: United States (except Hawaii), Australia, Europe
Restricted in: Japan
Best for: Sun damage and burn prevention
Coral safe? No, may also potentially affect fish
Caution: Sensitive skin types will want to skip formulas with this ingredient

Oxybenzone, often found in broad-spectrum sunscreens, helps filter both UVB and UVA rays (specifically short UVA). It’s also one of the most popular ingredients, found in the majority of sunscreens in the U.S. market and can make up to 6 percent of the bottle.

However, Hawaii has banned this ingredient after a study, created by the Haereticus Environmental lab, found that the ingredient contributed to bleaching and poisoning coral reefs. For environmental reasons, you’ll want to avoid this ingredient and look for “green” sunscreens.

Most recently, a studyTrusted Source found that our skin absorbs sunscreen ingredients like oxybenzone. This caused a spike of interest in “safe” sunscreens, despite the study reporting no harm found and concluding that “these results do not indicate that individuals should refrain from the use of sunscreen.”

Other studiesTrusted Source also confirm that oxybenzone doesn’t significantly demonstrate endocrine disruption.
