Everyone knows there is a risk of developing skin cancers by exposing unprotected skin to the sun and that risk increases depending on how long you’re in the sun and when. Where you live also increases or decreases your risk.
Factors such as time of day latitude, altitude, and time of year change the amount of UV’s you’re exposed too. The EPA’s sunwise app predicts UV levels based on these factors. Other personal risk factors include, facial cleansers, fair skin, blue eyes, red hair, and freckles.
Every year companies review the Effectiveness of and harm caused by sunscreens. Prior to 2014, there were no regulations on sunscreen effectiveness, ingredients, or claims of preventing skin cancers.
In 2011, after 4 years of multiple articles being published about the harmful ingredients and lack of actual protection, standards were created by the FDA. In 2014, testing standards were implemented. Although, the US standards are lower than Europe’s. Now in the US, companies can no longer use the claim that their sunscreen “prevents skin cancers.”
Ongoing air pollution has increased our risk of skin cancers. Cases have increased by 35% over the last 30 years. The FDA also, now, requires sunscreen to screen both UVA and UVB rays. But about half of products do not screen them equally and they could not be sold in Europe.
Most sunscreen companies have stopped putting a harmful type of vitamin A, retinyl palmitate, in its product. This ingredient may increase the speed of developing melanoma. However, consumers should still check for it-14% contained it in 2017.
Higher SPF claims do not mean more screening. SPF over 50 is misleading and does not mean more protection. Most countries cap the SPF claim at 50. The FDA is drafting a regulation to address this issue.
Nor are the claims of sweatproof, waterproof, or sunblock entirely accurate and thus no longer allowed to be printed on the screens. A skin cancer warning is required.
Spray on sunscreen are not as effective as creams/lotions. They don’t go on evenly or thick enough. There is a danger of inhalation as well.
Sunscreens need to be reapplied every two hours and sunscreen is not enough. If you’re going to be in the sun for long periods of time or between 10 am and 4 pm wear UV protective clothing, a hat and sunglasses.
Indoor tanning is also a big no-no. It increases your risk of all types of skin cancer including melanoma, which is the most dangerous. It’s illegal for someone under the age of 18 to use indoor tanning beds in most countries, including the US. It’s like smoking when you know the risks for cancer and other health problems. You are actually more likely to get skin cancer from indoor tanning than you are lung cancer from smoking (although it may cause other serious health/lung issues).
