Skin damage from the sun can happen no matter what time of year it is. Whether you are skiing or swimming, one of the most important ways to keep your skin safe is by wearing sunscreen.
It is now easier to protect your skin than ever before. All sunscreen lotion labels will soon get a face lift to make it easier for you to pick the right sunscreen. Next time you shop for a sunscreen, look for the new “broad spectrum” label on the package.
Broad spectrum means that a product can block UVA and UVB sun rays equally. UVA and UVB rays can cause skin cancer, early skin aging and sunburn. In the past, sunscreens mostly protected your skin from UVB rays that cause sunburns.
Products that are not broad spectrum will have a warning on the label saying they will not protect you against skin cancer and early skin aging. To learn more check out, “How Sunscreen Works.”
Some sunscreens have names that are misleading. Because you have to reapply sunscreen to stay safe, products can no longer say they:

Water or sweat resistant lotions can keep you safe when you sweat or swim. Labels on these products will now state on the label how long they can protect you before you should reapply. These products will last for either:
Try this tip when you are at the pool! Reapply water resistant sunscreen during every rest break or “adult swim.”
Everyone’s skin can benefit from sunscreen. Sunscreen that does not have a broad spectrum label will NOT protect you from skin cancer and early skin aging. These changes are only for sunscreen lotion and not spray because you put on spray sunscreens differently than lotions. For the best protection, follow these guidelines.
Use at least an SPF 15 up to an SPF 50. SPF stands for Sun Protection Factor or how much sun protection a product offers. The higher the SPF value of the sunscreen, the better protection it will offer. But this is only up to SPF 50. Sunscreens with an SPF greater than 50 still work, but it is unclear if they work any better than SPF 50 lotions.
Use broad spectrum sunscreen with an SPF of 15 or higher. Broad spectrum SPF 15 products can protect your skin against sunburn, skin cancer and early sun aging.
If swimming or sweating, use a water or sweat resistant product. Sunscreen that is not water resistant will have a label telling you to use a water resistant product if you are sweating or swimming, but remember to reapply every 40 or 80 minutes, depending on the directions.
Read the label. All sunscreens must include “drug facts” on the label that tell you:
Spending time in the sun puts you at risk for skin damage. Use the following sun protection tips, in addition to slathering on broad spectrum SPF 15 (or higher) sunscreen, to lower your risk of skin cancer, early skin aging, and sunburn!

If you already have sunscreen in your house, it is still safe to use. But, it may not protect you from the UVA rays that cause skin cancer and early skin aging. Sunscreen works well for up to three years. So, if your sunscreen is more than three years old or has been sitting in high temperatures, you may want to throw it out.
Don’t let the sun stop you from enjoying the outdoors. Lather up at least every two hours with broad spectrum sunscreen and keep your skin healthy!
