This makes sun protection safer

Usually, I am very proud of my Irish heritage, but my ancestors have also left me with a lot of problems, that is, pale, especially sunburned skin. When my mother was pregnant with me and my twin brother, the doctor found a large melanoma on her leg and needed immediate surgery. Fortunately, we are all safe and sound, but family history and skin colour, I have a higher chance of suffering from melanoma and other skin cancer. In the past 10 years, the global incidence of skin cancer has increased significantly. Asians with darker skin originally thought that they have less skin cancer, but due to various effects such as ozone, air pollutants and infection, the data indicates the incidence of skin cancer in China. There is also an upward trend. The Hong Kong Cancer Authority's Hong Kong Cancer Data Statistics Centre shows that there were 430 new cases of skin cancer in Hong Kong in 1997 and 815 new cases in 2007. The figure has nearly doubled. sunscreens cancer SPF

What are the basic considerations for sunscreens cancer SPF in sun protection? Parents especially need to protect their children from the sun. In fact, many studies have shown that if a child has a severe sunburn and blisters in the wound, it will be melanoma, squamous cell carcinoma and basal after adulthood. The main risk of cancer in cells. The American Academy of Pediatrics believes that babies under six months of age should not be exposed to direct sunlight because their skin is particularly fair and delicate. For most children and adults, use sunscreen, proper clothing, and avoid going out at 10:00 am - 4 pm (or refer to your location's UV radiation index) when the sun is strongest, which is the most important way to avoid injury.

How important is clothing? For people of all ages, it is the first line of defence against the sun, but the snow-white T-shirt has only 7 Sunburn Protection Factor (SPF), so it is easy to get sunburn when wearing this type of clothing. Thicker darker garments offer SPF 15 and even higher protection. But I am also very depressed to understand one thing, that is, if I am swimming outside all day, even a dark T-shirt is not enough.

At this time, sunscreen will come in handy. Studies have shown that high-quality sunscreen products can reduce the risk of skin cancer, especially squamous cell carcinoma. An Australian study showed that 40% of the risk of developing these cancers was due to the use of SPF16's broad-spectrum sunscreen products. The evidence that sunscreens fight against more deadly melanoma is actually not that powerful. The best-known research is published in the Journal of Clinical Oncology in 2010. This randomized, double-blind trial tracked 1,600 people in Australia in 10 years, and Australia is the region with the highest incidence of skin cancer worldwide. Those who used sunscreens were 73% less likely to develop invasive melanoma, but the editorial evidence published in the article questioned the statistical significance of the study. Having said that, I still agree with the editor's conclusion: "There are doubts about the efficacy of sunscreen products in preventing melanoma, but researchers and doctors should not stop there and no longer recommend sunscreen products... except for sunscreen Products, people should also avoid excessive exposure to ultraviolet light, should wear clothing to protect the skin from the sun, and outdoor recreation facilities should also be equipped with sun protection facilities. Also, in addition to the use of sunscreen products, people should regularly self-skin check."

But what is a good quality sunscreen product? Now, in the shopping malls of big cities in China, I am afraid I can find a whole wall of sunscreen products. There are dozens of brands in the brand, the packaging is colourful, the SPF value is very different, and it is said to be tailor-made for infants, women and men. The products that make us dazzled as consumers. So, let's take a look at the basic requirements for choosing a sunscreen product:

Buying a broad-spectrum sunscreen product: The SPF value of 50 or even 70 on the product does not mean that this thing is particularly good because the SPF rating system measures only UV-B rays in the sun and does not measure UV-A rays. UV-A rays usually don't make you a big red face, but it's much more sinister and can penetrate deeper into your skin, resulting in more subtle but more persistent pre-cancerous DNA damage. Therefore, when purchasing sunscreen, you should refer to the new regulations of the US Food and Drug Administration to purchase products marked with the word "broad spectrum" on the mark. This indicates that its formulation can block both UV-A and UV-B radiation.

SPF30 is enough, don't waste money on SPF50 or higher: SPF15 is a good start product because it blocks 93% of UV-B rays, but I agree with the American Academy of Dermatology. It is recommended that products of SPF30 are usually used. SPF50 or higher seems to be quite cool, but the extra protection from the clinical point of view is very small compared to SPF30 sunscreen. SPF30 blocks 97% of UV-B, while SPF50 is only one percentage point higher, up to 98%. In fact, the EU believes that this will be extremely misleading to consumers, so all products are prohibited from marking more than SPF50, and the US Food and Drug Administration is also finalizing the late ban.

The amount used is more, and more: research shows that many of us use sunscreens at a time that is not enough, which prevents us from getting adequate protection. Usually, adults need to wipe 1 ounce (30 ml) of sunscreen every time to protect themselves from head to toe.

Don't stay outdoors for too long: Many doctors think that everyone, especially children, is still exposed to the sun for a long time after rubbing the sunscreen, forgetting to apply it repeatedly according to the guidelines, or not using enough at the beginning, and this will increase the risk of suffering from melanoma.

Use throughout the year: This statement may surprise many people, but the American Academy of Dermatology recommends doing this. Ultraviolet rays may be weaker in spring, autumn and winter, but they can still accumulate and cause skin damage. You should at least consider brushing an SPF value of at least 15 per day and rubbing your face, ears and neck. I have been using SPF20's aftershave every day since I was in college.

The ingredients of sunscreen products are also varied, with many approved compounds, and this will definitely deepen your doubts. Some organizations, especially the Environmental Working Group, an independent environmental health research and advocacy group based in Washington, DC, claiming that two common ingredients in sunscreen products are hydroxybenzoxazole and retinyl palmitate (vitamins). A derivative is harmful to health and should not be found in sunscreen. For example, the organization's web page describes the dangers of hydroxybenzazole, including "destroying hormones; found in long-term feeding studies that can affect fertility, alter organ weight, increase photoallergic chances; and a small amount of evidence suggests that neonatal birth weight can be altered to increase the possibility of endometriosis in women." However, no drug regulatory authority in any country has banned the use of this ingredient, and no large medical institution agrees with this organization. The research cited by this organization is mainly carried out on animals or in test tubes. There are no human tests and no large human trials have shown that it can cause serious harm. Both the United States, the European Union, and Canada consider these two compounds to be safe and remain so after more than 20 years of use. In the statement issued by the American Academy of Pediatrics on sunscreen, no warning was given to compounds or other food and drug regulatory approvals for compounds used in sunscreen. The American College of Dermatology published an updated version of the statement last summer, reiterating support for both ingredients.

If you still have concerns about these ingredients, there are hundreds of sunscreen products on the market that are completely free of these two ingredients, and still, provide you and your children with the perfect broad-spectrum sun protection. Hydroxybenzoxazole is not as effective as other compounds in sunscreen, such as avobenzone, so you can find alternatives. The retinyl palmitate is not an essential ingredient. It does not block the sun. It is said to be added to the sunscreen to prevent skin ageing due to sun exposure. The American Academy of Pediatrics specifically recommends products containing zinc oxide or titanium dioxide because they are physical sunscreens that are not absorbed by the skin. If you want more consumer guidance, you can read the independent test results of Consumer Reports, or refer to the Consumer Search guidelines for sunscreen ingredients. This guide also applies to natural sunscreens. Supplies have been reviewed.
