The influencers also publish “toxic”, what is the truth about sunscreen? | sciences
It is the summer in the United Kingdom and social media soaked with influencers who broadcast their concerns about sunscreen. Among them is the reality TV star, Sam Fires, from The Lost The Way is Essex, who is believed to be a sunscreen “full of toxic ingredients.” She said that none of her family is wearing a sunscreen, adding that her children had built a “really good tolerance” of the sun. Some allegations appear to be fueled by an American doctor who told his followers: “Be careful with what you distort yourself and your children.” Here we look at the flag behind sunscreen and sun exposure.
How does sunlight damage the skin?
Everything reaches high -energy UV rays (UV). These cause early skin aging and wrinkles by decomposing collagen and elastin. Collagen gives the skin its package and structure, while the elastin makes it extended. UV rays can also harm DNA in the skin cells, which eventually leads to skin cancers. One of every three cancers worldwide is skin cancer, and the main driver is UV rays.
“Many UV rays of the sun are the main cause of skin cancer, and the most dangerous type of skin cancer,” said Dr. Claire Knight from UK research cancer. “This is why it is important to develop good sun safety habits from an early age and protect your skin when the sun is strong using shade and sunscreen together.”
Can you develop tolerance with the sun?
When sunlight reaches summer, the skin responds to protect itself. The outer layer, the skin, thickens and develops many people Tan, as the cells in the skin are called pigment cells produce more melanin absorbent ultraviolet. Not everyone though, and the acquisition of Tan itself leads to DNA damage.
“Most of this damage is fixed, but some do not, cause mutations and can continue to grow throughout his life to cause skin cancer,” said Brian Derevi, a professor of empty science at Newcastle University. “The sun in childhood displays a critical period for developing skin cancer, especially skin cancer, later in life.”
It is recommended to use a sunscreen when the sun can harm your skin and not disturb it when the UV index is less than three, and it is generally in the United Kingdom from mid -October to mid -March.
How does sunscreen work?
Sun creams contain ultraviolet rays. It protects by reducing the amount of UV rays that reach the skin as it can cause burning and other damage.
There are two main types of UV filters. The first is inorganic compounds, usually zinc oxide and titanium dioxide. The second is organic compounds, where the membership simply means that they contain carbon. Both types are manufactured and add to creams, sprays, and lips. Many sunscreen contain inorganic and organic UV filters to improve sun protection.
Why fears?
They return to a 2019 study It was conducted by the US Food and Drug Administration (FDA). The researchers found the effects of organic UV filters, Avobenzone, Oxybenzone, Octocrylene and Ecamsule, in people’s blood after applying sun cream. The concentrations have exceeded the level in which the FDA recommends to conduct specific tests for toxic effects. Dr. True Kalayan, who runs a weight loss clinic in the United States, posted the paper on X, adding: “Be careful to distort yourself and your children.”
The study prompted the Food and Drug Administration (FDA) to invite more work on vehicles, but the authors confirmed that they did not follow the people from the products. “These results do not indicate that individuals should refrain from using sunscreen,” they wrote.
The study was considered in sunscreen under “maximum use conditions”, which really means shattering the cream. Under real circumstances, people apply about the tenth of those used in the study, Davi said. He added that alone would bring three of the four components below the FDA threshold.
How can ultraviolet rays cause harm?
Inorganic UV filters, zinc oxide and titanium dioxide have sparked some concerns because they are not easily absorbed into the bloodstream. However, they can still have an environmental effect when they wash the swimmers covered in the sun and accumulate in water and marine life.
More questions surround organic ultraviolet filters such as oxbensone. These are the endocrine glands, which means that they mimic natural hormones. Whether it causes damage to the doses that people get from wearing the sun’s cream is unclear, but a number to studies Look at the levels of benzovinones (which include oxbensone) in the urine and linking higher levels to the sperm and poor fertility, with affected husbands take longer until they imagine.
Will the sunscreen be reformulated?
Organizational bodies around the world seek to obtain more information from manufacturers on organic UV filters, but some countries are already taken action. The UK Office for Product Safety and Standards is planning to tighten the borders on Oxybenzone next year, making it more in line with Europe. Today, the UK’s sunscreen can contain up to 6 % of oxybinson, but in 2026, the maximum concentration will be reduced to 2.2 % for the products that are applied to the whole body. Creams and sprays for the face and hands, and the lips, can contain 6 %, as they are applied to small spots of the skin.
In Australia, the therapeutic goods management (TGA) recommended reformulating sunscreen protective and additional guarantee on three chemical compounds, including oxbensone. In the United States, the FDA Review is ongoing.
Does sunscreen cause a lack of cancer or vitamin?
Some social media publications have published allegations Sunscreen causes cancer, But this is a mistake. “There is no evidence for that,” said Anthony Young, an honorary professor of experimental photo science at King’s College College in London. “Skin cancers are caused by mutations, and almost all skin cancers have a very specific boom for UV rays.”
Others raise fears of vitamin D deficiency. In summer, most vitamin D is manufactured through the sun on our skin. but Young and his colleagues I found that sunscreen has a little effect on vitamin D that people make. The amount of sunlight needed to produce vitamin D is much lower than what is necessary to cause sunburn.
But isn’t sunlight healthy?
According to some doctors, fears of skin cancer may have shattered the broader health benefits of sunlight. hesitant research It indicates that people with more sunlight may suffer from a low risk of heart disease, high blood pressure, autoimmune diseases and even certain cancers. “Sunburn is a risk factor for skin cancer, but sunlight is useful for you,” said Professor Richard Wheeler of Edinburgh University. “You can use a sunscreen, you can use a hat, or you can broadcast inside, everything is good for you. Just not burn.”
“My general advice is to enjoy the sun, but it does not burn from the sun,” Young added. “You can limit your time, choose your time, or protect yourself, whether it is by shade, clothes or sunscreen. Soupse from the sun works.”
