Before you slather up with your sunscreen, be sure to read the label. The FDA’s new regulations are intended to help you better understand the protection you’re getting.
The FDA recently announced new requirements for over-the-counter sunscreens. Prior to these changes, the regulations on sunscreen only addressed concerns with protection against Ultraviolet B (UVB) rays. New standards now include regulations for Ultraviolet A (UVA) rays.
Understanding what you may see on new sunscreen labels will allow you to choose the right sun protection for you and your family.
Let’s start with a brief discussion about sunlight.
What is sunlight?
Sunlight consists of two types of harmful ultraviolet radiation: UVA rays and UVB rays.
UVA rays penetrate into the dermis, the thickest layer of skin and have long-term effects on the skin. They are known to lead to signs of premature aging such as wrinkles and age spots. UVB rays produce short term effects on the skin and are the primary cause of sunburn.
An easy way to remember is UVA rays are “aging” rays and UVB rays are “burning” rays. Both can cause skin cancer.
Why is it so important to protect my skin against sunlight?
Too much unprotected sun exposure can cause skin, eye damage or even cancer.
“One or more blistering sunburns in your childhood can more than double your chances of developing melanoma later in life,” says Stuart Siegel, MD, director of the Children’s Center for Cancer and Blood Diseases at Children’s Hospital Los Angeles.
Luckily, with the right precautions and use of sunscreen, you can greatly reduce the chances of developing skin cancer.
This is why it’s so important to always remember your sunscreen!
So, what do the new FDA rules mean for me?
Before you slather up with your sunscreen, be sure to read the label. The FDA’s new regulations (summarized below) are intended to help you better understand the protection you’re getting.
Sunscreens may be labeled as “broad-spectrum” only if they provide protection against both ultraviolet A and ultraviolet B radiation.
Only broad-spectrum sunscreens with a Sun Protection Factor (SPF) of 15 or higher can state that they protect against skin cancer if used as directed with other sun protection measures. Sunscreens with an SPF of 2-14 will be required to have a warning stating that the product has not been shown to help prevent skin cancer or early skin aging.
Sunblock, Sweatproof and “Waterproof” Defined
Manufacturers are no longer allowed to use the words waterproof, sweatproof or identify their products as sunblocks. Why? Because these descriptions overstate their effectiveness. Sunscreens cannot claim to provide sun protection for more than two hours without reapplication or to provide protection immediately following application (instant protection).
Waterproof Vs. Water-Resistant
A sunscreen may claim to be water-resistant, however, it must claim in minutes the amount of time for which the product is water resistant during swimming or sweating, based on test results.
All sunscreens must include standard “Drug Facts” information on the back and/or side of the labeling.
Cosmetics, moisturizers and any other products that claim to provide Broad Spectrum SPF protection are regulated as sunscreen drug products. That means these new regulations also apply to these products.
For the Future
A proposal pending approved would limit the maximum SPF value on sunscreen labels “50+” because there is insufficient data to prove that these products greater protection for users than products with SPF values of 50. The new rules will take effect by summer of 2012, but some sunscreen manufacturers are launching their new labels before then.
The most important way to protect you and your family is to read the label carefully!
Look for a “broad-spectrum” sunscreen that will protect you from both UVA and UVB radiation with an SPF value of at least 15. Keep in mind that a sunscreen with an SPFT of 30 – 45 SPF is recommended, in combination with other protective measures.
Don’t be fooled by the term “waterproof” because all sunscreens eventually wash off. Note how long the sunscreen remains effective when swimming or sweating and reapply often.
The Eyes Have It
Also, don’t forget your children’s eyes when spending time in the sun.
“Look for kids’ sunglasses that block 99 to 100 percent of both UVA and UVB rays when shopping for kids’ sunglasses,” says Thomas Lee, MD, a pediatric eye surgeon at The Vision Center at Children’s Hospital Los Angeles. “Exposure to bright sunlight can result in eye irritation and the development of cataracts later in life.”
