Use that Sunscreen!

To protect your skin against harmful rays that can lead to skin cancer, your dermatologist places a strong emphasis on applying sunscreen to your skin. Sunscreen is a highly recommended defense against sunburn and skin cancer. It is now available in lotions, creams, ointments, gels, wax sticks and spray.  
The best kind of sunscreen depends on you. It is good to use a product that has a higher SPF, but it is more important you find a sunscreen that you like because you will use it more. Make sure you apply sunscreen at least 15 to 30 minutes before you go out into the sun.  
Put on enough sunscreen so that it takes a full minute to rub in. If you are at the beach, be sure to spread at least one ounce on your face and entire body. Use more if you need to for good coverage. If you go for a swim or are outdoors for an extended period of time, reapply your sunscreen every two hours.  

Ouch! I think I have Sunburn    

Many beach and pool goers often complain of sunburn, which is a visible reaction of the skin’s exposure to ultraviolet (UV) radiation, the invisible rays that are part of sunlight. Signs of sunburn may not appear for a few hours, and the full effect to your skin may take up to 24 hours to appear, but when you have sunburn you will know. Ultraviolet rays can also cause invisible damage to the skin. Excessive or multiple sunburns cause premature aging of the skin and can lead to skin cancer.  
Sunburns typically heal on their own in a couple of weeks, but there are ways to alleviate the pain caused by them. It is often recommended that you take a cool bath or gently apply a cool, wet compresses to the skin when sunburn develops. You many also take a pain reliever to help with the pain, but it is also important to rehydrate your skin to help reduce swelling by applying aloe.  
Visit your dermatologist for more information on how to protect your skin this summer and to find out what to do when you suffer from sunburn.

SunscreenSPF -- choosing the best Sunscreen for Optimal Skin Protection

There are 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? Advanced Desert Dermatology 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 and even 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.
