No matter the weather, sun safety must be a priority. Sun exposure can cause skin aging, eye damage, sunburn, and skin cancer, which is the most common form of malignant tumor in the US. Fortunately, this type of cancer can be prevented with the use of sunblock. But, when it comes to sunblock products, there are three words you need to remember — sun protection factor (SPF).
Sunblock in Lowering Risk for Skin Cancer
The sun’s invisible UV radiation causes damage to the body. The FDA recommends using broad-spectrum sunblock with an SPF value of at least 15. The agency adds that you “use a broad-spectrum sunscreen with an SPF of 15 or higher, even on cloudy days.” It means that even if there’s a storm outside and you need to go out, you must still apply or wear anything that can lower your risk for sunburn.
Where to Apply and When to Reapply the Sunscreen?
You should apply sunblock to all uncovered skin. It means that you have to use it on your nose, neck, lips, hands, and feet. But you must avoid applying it to your mouth and eyes. When it comes to re-application, you should do it at least every two hours. But if you’re out swimming or you sweat a lot, you need to apply more often. If you have an average size body, you need an ounce of sunscreen each day to cover your body evenly.
What You Must Look for When Reading Sunscreen Labels?
Broad Spectrum
Both UVA and UVB rays contribute to skin cancer. However, the primary cause of sunburn is UVB. Unfortunately, all sunscreens can only protect you against sunburn. If you wish to protect yourself from both UV rays, you need to use a product with a broad spectrum that can lower your risk of skin cancer. It can also reduce early signs of skin aging as a result of sun exposure.
Water Resistance
There’s no such thing as waterproof sunscreen. The FDA advises manufacturers not to make claims that their products are waterproof or sweat-proof. On the other hand, if the product is water-resistant, it must tell the user how often to re-apply the protection to the skin.
Time in the Sun
Even though you have applied sunblock, you still need to limit your time in the sun. Avoid going out in the sun between 10 am and 2 pm. The sun’s rays at these times are most intense. Even if you wear sunscreen, you may still suffer from the side effects of the sun’s rays.
