5 Myths of Sunscreen to Prevent Skin Cancer
Using sunscreen is an obligation for everyone. Regardless of weather conditions and environmental temperature, it is undeniable, sunlight can still penetrate into our skin. Therefore, our skin needs extra protection from sunscreen.
The use of this sunblock becomes a bit of a trap. There are many rumors and myths circulating about how sunscreens work. Misuse of sunscreen can also cause skin problems such as cancer.
In the United States, as many as 3.5 million are diagnosed with skin cancer per year. Basal and squamous cancer cells, which increase 95 percent of the causes of skin cancer, arise from frequent exposure to UV rays from the sun entering the skin. Exposure to UV rays for just 15 minutes can damage our skin tissue.
With that, the use of sunscreen has become important for all people, both men, and women. Pay attention to the myths related to sunscreen to avoid mistakes and mistakes in using sunscreen.
All sunscreens have strong UV protection
Not all sunscreens have sufficient levels of UVA and UVB protection, In fact, not all sunscreens on the market have sufficient protection against UVA and UVB rays. They can indeed prevent our skin from getting sunburned when used properly. However, the reality is that many sunscreens do not have sufficient UVA protection.
Reporting from ewg.org, UVA, and UVB both have the strongest impact on causing skin cancer. However, UVA can penetrate deeper into the skin, which can make the skin age faster and cause wrinkles. Meanwhile, UVB can cause sunburn and inflammation. Therefore exposure to UVA rays can be the cause of prolonged skin problems.
The FDA states that skin protection against these two rays is also important. However, there are still many or about 70 percent of sunscreen products that do not meet these standards.
The higher the SPF of the sunscreen, the higher the protection
No sunscreen is 100 percent able to block UV rays, In fact, there is no SPF that can completely protect the skin from UV rays. Reporting from cancercenter, SPF 30 can only block as much as 97 percent of UV rays, the rest will only add one or two percent, but not 100 percent. The duration of the deterrence is the same, which is only about two hours or less.
Therefore, using SPF 15 to SPF 50+ is also recommended for everyone. Because research by the FDA proves that the use of sunscreens above SPF 50+ can cause high exposure to UVA rays. This can also increase the potential for skin cancer because a high SPF will not provide a sufficient level of UVA protection for the skin.
Using sunscreen can lead to Vitamin D deficiency
There are many rumors that dark skin doesn't need the same sun protection as lighter skin. In fact, sunscreen is important for all skin. Vitamin D, a hormone that supports strong bones and a strong immune system, can be produced when the skin is exposed to UVB rays. This has also led to the discussion that sunscreen can lower the level of vitamin D in the body.
However, as reported by ewg.org, there are no studies that discuss UVB exposure that is safe for the body. Therefore, it is advisable to keep wearing sunscreen when you want to sunbathe and enjoy the sun. To avoid vitamin D deficiency can also be circumvented by consuming foods or supplements that have high levels of Vitamin D.
No need to use sunscreen for indoor activities
Even activities from home need sunscreen, In fact, even though we do activities from home, UV rays can penetrate through the glass and windows of our homes. Reporting to ewg.org, the American Cancer Society states that some windows can protect against UVB rays, but UVA rays can still penetrate windows. Therefore, if we live in a house with windows that can be exposed to sunlight, wearing sunscreen is also important.
Blue light rays can also trigger the potential for damaged skin. This light comes from skin contact with light from our gadgets, such as cellphones, computers. TVs and other light-generating electronic devices. Research has shown that blue light gives skin the same aging effect as UVA rays.
SPF can be obtained from the use of makeup with SPF
The SPF of makeup is not necessarily enough to protect the skin from UV rays
In fact, with only SPF makeup, our skin will not get full UV protection. Chances are we use makeup only in areas of the face that we want. Therefore, the use of sunscreen becomes mandatory before we override it with makeup so that the face can't obtain adequate UV protection.
For facial treatments such as moisturizers or moisturizers that claim to have SPF protection, sometimes there are mistakes in them. Even though these facial treatments contain SPF, we still have to reuse them regularly. Because the SPF can fade from our bodies, so the protection is reduced.
