SunscreenWe know that you’re excited about summer and all of the outdoor fun. From backyard BBQs to weekend getaways to the beach, summer is many people’s favorite season (and we can see why); however, you must spend some time thinking about the health of your skin, especially if you plan to spend any time outdoors. As any dermatologist will tell you, being out in the sun without sunscreen can lead to serious sunburns and sun damage and can increase your risk for skin cancer.

Wear Sunscreen Daily

You really should be wearing sunscreen every day, regardless of whether it’s summer or not. Even if the day isn’t feeling particularly warm, the sun’s rays can still penetrate and damage the skin. Even on cloudy and rainy days, you’ll still need to apply sunscreen because the sun’s rays can penetrate through clouds.

If you want to protect your and your family’s skin all summer long, make sure to apply a generous amount of sunscreen to the face and body 30 minutes before going outside.

Know What Sunscreen to Use

Not all sunscreen is created equal. You must look for a sunscreen that is broad-spectrum, which means that it will protect against both UVA and UVB rays. You should also use a sunscreen that has, at the very least, an SPF of 30. If you want to opt for a higher SPF that’s always a good idea, but don’t be lured into a false sense of security. Just because the SPF is higher doesn’t mean that you can spend all day lounging in the sun without needing to reapply. This brings us to our next order of business…

Reapply Sunscreen Regularly

Just because you put sunscreen on once doesn’t mean that it lasts all day long. If you are going to be outside for hours at a time you will need to bring your sunscreen with you and reapply every two hours. If you are sweating or swimming you will also need to reapply immediately after.

No matter your risk for skin cancer, it’s important for everyone to get a yearly skin cancer screening. This simple, non-invasive checkup can help us spot suspicious growths and moles early to prevent cancer from getting worse.

SunscreenThere is a wide variety of sunscreens available, including lotions, sprays, creams, gels, wipes, and lip balms, to name a few. These topical products absorb or reflect some, but not all, of the sun's ultraviolet (UV) radiation on the skin to help protect against sun damage. But which one is right for you? Our practice can help you find the best sunscreen for your needs and lifestyle.

SPF - what's in a number?

SPF (Sun Protection Factor) provides an indication of how effectively a sunscreen can protect your skin from the ultraviolet-B (UVB) light - the rays that cause sunburn and skin cancer. A higher SPF number represents a higher level of protection. The American Academy of Dermatology recommends sunscreen products with a sun protection factor of at least 30.

Today, sunscreens with SPFs as high as 100 are available, but a higher number doesn't necessarily mean more protection. For instance, many people believe a sunscreen with SPF 45 would give 3 times as much protection as one with an SPF of 15. This is not true. SPF 15 sunscreens filter out about 93% of UVB rays, while SPF 30 sunscreens filter out about 97%. SPF 50 sunscreens filter approximately 98% while SPF 100 provides 99%. The higher you go, the smaller the difference becomes. No sunscreen can provide complete protection.

Apply Sunscreen Properly

Regardless of the SPF rating, sunscreen should be reapplied often for optimal protection. A majority of people do not apply a layer of sunscreen thickly, so the actual protection they get is less. For best results, most sunscreens must be reapplied at least every two hours, more often if you are swimming or sweating. Apply sunscreen generously, paying close attention to face, ears, arms, neck and all other areas exposed to the sun. Sunscreens do expire, so always check the expiration date to make sure it is still effective.
