Oriental Network reporter Fu Wenjing reported on May 8: Today, a message of "sunscreen or harmful ingredients" was on Weibo's hot search. The reason is that on May 7, CNN reported that a new study released by the US Food and Drug Administration (FDA) shows that the active ingredients in sunscreens can be absorbed into the bloodstream, which may pose a risk to human health.

According to a research article published in the Journal of the American Medical Association, the active ingredients of common sunscreens require further testing and do not ensure safety. In the study experiments conducted, the researchers asked 24 healthy subjects to apply one of four types of chemical sunscreen and 75 percent of the skin of the whole body in a standard dosage. The experiment required subjects to apply 4 times a day for 4 consecutive days. Subsequently, the researchers conducted blood tests on the subjects and found that after only one day, the four active ingredients that penetrated into the blood of the subjects: avobenzone, oxybenzone, octelinine and ephrosole, all exceeded the safe levels specified by the FDA.
It is reported that the research article said that it is not clear what kind of impact the chemical components of sunscreen will have on the human body after being absorbed by the human body and entering the blood flow, but at the end of the article, the researchers said that the results of the study do not mean that people should stop using sunscreen, but hope that sunscreen manufacturers and regulatory agencies can strengthen the safety monitoring and evaluation of sunscreen ingredients.
Netizen discussion
Dermatologists at Yale University School of Medicine point out that the sun is the biggest enemy, and people still need to actively protect themselves from sunscreen to prevent diseases such as skin cancer. According to the World Cancer Research Fund, skin cancer ranks 19th among the most common cancers in the world. For the question of whether they dare to continue to use sunscreen, netizens have expressed their opinions. Some netizens said, "Study you despite the sunscreen I still apply." Some netizens also said that they are allergic to ultraviolet rays, "the two harms are lighter", sunscreen still has to be used.
Although the health effects of the ingredients in sunscreen on the human body are not clear, the harm of sunscreen to marine life has long been confirmed. From 2021, Hawaii will ban the sale of sunscreens containing oxybenzone or cinnamonate to protect coral reef ecology and become the first state in the United States to ban related chemicals.

Oxybenzone and cinnamonate are known to cause DNA damage to corals and cause young coral growth deformities, as well as bleaching corals when exposed to sunlight. In addition, oxybenzone and cinnaminate can also harm the DNA of organisms such as sea urchins, fish sperm and eggs. Hawaii is surrounded by coral reefs, so in order to preserve and restore the ecology of coral reefs, it is necessary to "kill" sunscreens containing the above ingredients.
