Sunscreen

Sunscreen

Recently I headed out to the local splash park with five kids! I thought I was doing a really fun thing for all the kids (only two of which are mine) by taking them out for a day of fun, sun, & splash.

I had carefully packed lunches, filled water, and picked up sand toys. All kids were ready! When we got there I organized everything (not cause I am super women, but with five kids you have no choice but to be organized) I applied sunscreen and the kids were ready!

All day we played, ate, and enjoyed the sun. I kept a close eye on the fair skin kids. You see mine a dark olive skinned and I can apply sunscreen once and forget about it. I have never had the unfortunate affects of sunburn on my kids. I was nervous about making sure the blondies in my brood didn’t get pink.

So you can imagine my surprise when my little toe head day care girl showed up today with a burn on her back from the sun. OMG I felt so bad, but how did this happen. I applied three or four times and kept giving them the finger poke check (I hated that when I was little)! I thought I had executed the perfect summer outing. But I was wrong!

I was baffled as to how this could have happened and it bugged me all day. So I went looking for answers.

Come to find out there are many rules to sunscreen that I was unaware of! Such as, you should get a new bottle every year. Since my boys and I apply once and forget it, we never go through an entire bottle and I have had mine for two years. Apparently, the active ingredients expire and break down over time. Therefore, the cream I applied to my fair-skinned charges was pretty much useless. Thank God their burns were not worse and they did have some protection from the lotion it’s self so that helped.

There were plenty of other things I found out too here are some eye openers from www.the skincancerfoundation.org

Excerpt from The Skin Cancer Foundation:

The sunscreen aisle of a drugstore offers lots of choices, but which one is right for you? We show you how to find the sunscreen that best fits your lifestyle.

What Are Sunscreens?
Sunscreens are chemical agents that help prevent the sun’s ultraviolet (UV) radiation from reaching the skin. Two types of ultraviolet radiation, UVA and UVB, damage the skin and increase your risk of skin cancer.

UVB is the chief culprit behind sunburn, while UVA rays, which penetrate the skin more deeply, are associated with wrinkling, leathering, sagging, and other effects of photoaging. They also exacerbate the carcinogenic effects of UVB rays, and increasingly are being seen as a cause of skin cancer on their own. Sunscreens vary in their ability to protect against UVA and UVB.

What Is SPF?
Most sunscreens with an SPF of 15 or higher do an excellent job of protecting against UVB. SPF—or Sun Protection Factor—is a measure of a sunscreen’s ability to prevent UVB from damaging the skin. Here’s how it works: If it takes twenty minutes for your unprotected skin to start turning red, using an SPF 15 sunscreen theoretically prevents reddening fifteen times longer—about five hours.

Another way to look at it is in terms of percentages: SPF 15 blocks approximately 93 percent of all incoming UVB rays. SPF 30 blocks 97 percent; and SPF 50 blocks 98 percent. They may seem like negligible differences, but if you are light-sensitive, or have a history of skin cancer, those extra percentages will make a difference. And as you can see, no sunscreen can block all UV rays.

But there are problems with the SPF model: First, no sunscreen, regardless of strength, should be expected to stay effective longer than two hours without reapplication. Second, “reddening” of the skin is a reaction to UVB rays alone and tells you little about what UVA damage you may be getting. Plenty of damage can be done without the red flag of sunburn being raised.

Who Should Use Sunscreen?
Anyone over the age of six months should use a sunscreen daily. Even those who work inside are exposed to ultraviolet radiation for brief periods throughout the day. Also, UVA is not blocked by most windows.

Children under the age of six months should not be exposed to the sun. Shade and protective clothing are the best ways to protect infants from the sun.

What Type of Sunscreen Should I Use?
The answer depends on how much sun exposure you’re anticipating. In all cases we recommend a broad-spectrum sunscreen offering protection against both UVA and UVB rays.

Many after-shave lotions and moisturizers have a sunscreen (usually SPF 15 or greater) already in them, and this is sufficient for everyday activities with a few minutes here and there in the sun. However, if you work outside or spend a lot of time outdoors, you need stronger, water-resistant, beachwear-type sunscreen that holds together on your skin. The “water resistant” and “very water resistant” types are also good for hot days or while playing sports, because they’re less likely to drip into your eyes. However, these sunscreens may not be as good for everyday wear. They are stickier, don’t go as well with makeup, and need to be reapplied every two hours.

Many of the sunscreens available in the US today combine several different active chemical sunscreen ingredients in order to provide broad-spectrum protection. Usually, at least three active ingredients are called for. These generally include PABA derivatives, salicylates, and/or cinnamates (octylmethoxycinnamate and cinoxate) for UVB absorption; benzophenones (such as oxybenzone and sulisobenzone) for shorter-wavelength UVA protection; and avobenzone (Parsol 1789), ecamsule (MexorylTM), titanium dioxide, or zinc oxide for the remaining UVA spectrum.

How Much Sunscreen Should I Use and How Often Should I Put it On?
To ensure that you get the full SPF of a sunscreen, you need to apply one ounce—about a shot glass full. Studies show that most people apply only half to a quarter of that amount, which means the actual SPF they have on their body is lower than advertised. During a long day at the beach, one person should use around one half to one quarter of an eight-ounce bottle. Sunscreens should be applied thirty minutes before sun exposure to allow the ingredients to fully bind to the skin. Reapplication of sunscreen is just as important as putting it on in the first place, so reapply the same amount every two hours. Sunscreens should be reapplied immediately after swimming, toweling off, or sweating a great deal.

Common Myths
Wearing sunscreen can cause vitamin D deficiency. There is some controversy regarding this issue, but few dermatologists believe (and no studies have shown) that sunscreens cause vitamin D deficiency. Also, vitamin D is available in dietary supplements and foods such as salmon and eggs, as well as enriched milk and orange juice.

If it’s cold or cloudy outside, you don’t need sunscreen. This is not true. Up to 40 percent of the sun’s ultraviolet radiation reaches the earth on a completely cloudy day. This misperception often leads to the most serious sunburns, because people spend all day outdoors with no protection from the sun.

Eighty percent of your sun exposure comes as a child, so it’s too late to do anything now. It appears that this universally promoted idea was based largely on a misinterpretation. A recent multi-center study showed that we get less than 25 percent of our total sun exposure by age eighteen. In fact, it is men over the age of 40 who spend the most time outdoors, and get the highest annual doses of UV rays. And since adult Americans are living longer and spending more leisure time outdoors, preventing ongoing skin damage will continue to be an important part of a healthy lifestyle.

Buy a high-quality product with an SPF of 15 or higher; check its ingredients to make sure it offers broad-spectrum protection; and decide whether it works better for everyday incidental use or extended outdoor use. Finally, look for The Skin Cancer Foundation’s Seal of Recommendation, which guarantees that a sunscreen product meets the highest standards for safety and effectiveness. Once you choose the right sunscreen, use it the right way. But remember, you should not rely on sunscreen alone to protect your skin against UV rays. By following our Prevention Guidelines, you can lower your risk of developing skin cancer, while helping your skin look younger, longer
