Whats the Difference Between Sunblock and Sunscreen?

Sunblock is different than sunscreen. An organic sunblock physically blocks the sun’s UV radiation of the skin, both UVA and UVB. Examples of natural sunblock are clothing, umbrellas, and trees. Chemical sunblock scatters, reflects, and physically blocks UV radiation. The most well-known physical organic sunblock is zinc oxide. Other commonly used organic sunblock is talc, titanium dioxide, and red vetenary petrolatum.

Sunblock does have some disadvantages. Many older chemical sunblock is opaque, the skin can not be seen through the sunblock. This may not be cosmetically acceptable for many people. They can also be greasy and clog pores, a problem for people with acne-prone skin.

A new organic sunblock formulation has been developed that contains micronized titanium dioxide. The advantage of this formulation is that it is almost invisible and still has good UV blocking capabilities.

Suncare on the Slopes

Higher altitude means increased levels of harmful UV exposure compared to sea level areas. UV exposure increases 8-10 percent with every 1,000 feet above sea level. At an altitude of 9-10,000 feet, UV may be 45-50 percent more intense than at sea level. In addition, snow reflects about 80 percent of the UV light from the sun, meaning that you are often hit by the same rays twice. This only contributes to the problem, further increasing the risk for skin cancer.

The combination of higher altitude and ultraviolet (UV) rays reflected by the snow puts skiers and snowboarders at an increased risk of sun damage and ultimately, skin cancer. More than 90 percent of all skin cancers are caused by sun exposure. It’s easy to associate winter with frostbite and windburn, but most people are unaware that UV rays can be even more damaging on the slopes than on the beach,it’s important to take proper precautions while on the slopes.

Both snow and strong wind can wear away sunscreen and reduce its effectiveness, so you have to take extra precautions. To protect your skin from the bitter cold, heavy winds and winter sun, follow these important sun protection tips:
• Use a broad-spectrum sunscreen with an SPF of 15 or higher whenever you spend time outdoors. Apply 30 minutes before hitting the slopes.Be aware that the sun’s reflection off the snow is strong even on cloudy days.
• Apply sunscreen liberally and evenly to all exposed skin – most skiers and snowboarders do not use enough sunscreen and therefore do not get the maximum protection.
• Use a more moisturizing sunscreen. Winter conditions can be particularly harsh on the skin.
• Be sure to cover often-missed spots: lips, ears, around eyes, neck, underside of chin, scalp and hands.
• Always wear a lip balm with an SPF 15 or higher. Lips are even more sensitive than most parts of the skin.
• Reapply at least every two hours, and more often after sweating or exposure to wind and snow.
• Carry a travel-sized sunscreen and lip balm with you on the slopes. Reapply on the chairlift, especially after a long, snow-blown run.

Cover up.

• Wear items like ski masks, which will cover most of the skin, leaving very little exposed to the wind and sun.
• UV-blocking sunglasses or goggles that offer 100% UV protection and have wraparound or large frames protect your eyelids and the sensitive skin around your eyes, common sites for skin cancer and sun-induced aging. The sun’s rays and glare can impair your vision, so it’s important to wear sunglasses or goggles to clearly see the terrain. Plus, it will increase your enjoyment and performance while skiing.
Be mindful of time spent in the sun, regardless of the season.
• Keep track of the time you spend in full sunlight. If possible, ski early in the morning and later on in the day, before 10AM and after 4PM. This helps avoid long lines and decreases the amount of time spent outdoors in the most intense hours of sunlight.

• If you are on the slopes for most of the day, take a few breaks indoors to reapply sunscreen.
• Drink plenty of water to avoid dehydration from the sun.
Enjoy the winter season, but be sure to take care of your skin to avoid the damage the cold season can cause.

The first organization in the U.S committed to educating the public and medical professionals about sun safety, The Skin Cancer Foundation is still the only global organization solely devoted to the prevention, detection and treatment of skin cancer. The mission of the Foundation is to decrease the incidence of skin cancer through public and professional education and research.

Baby Sun Care Guidelines from the AAP

The best way to protect your baby is to keep your baby out of direct sunlight as much as possible, especially between 10 a.m. and 4 p.m., when the sun’s rays are strongest. Routinely dress him in a hat, lightweight pants, and a long-sleeved shirt for outings during the middle of the day. Tightly woven clothing protects better than loosely woven fabrics (to see how tight the weave is, hold the fabric up to a light – the less light that shines through, the better). Add UV-protective sunglasses if your baby will wear them. Use an umbrella, stroller canopy, or sun-protective tent to protect your baby while he’s outside.

Until August 1999, the American Academy of Pediatrics (AAP) recommended against using any type of sunscreen on babies younger than 6 months, because their skin’s ability to metabolize and excrete chemicals may not be fully developed. This recommendation has been revised somewhat.  You can use sunscreen on babies under 6 months if adequate clothing and shade aren’t available, but check with your pediatrician first.  If you use organic sunblock you can avoid chemical interaction altogether.  That doesn’t mean you should slather your baby in sunblock, though. Just apply a small amount of lotion to exposed areas.

For babies over 6 months, use a waterproof sunscreen designed for children. Choose a sunscreen labeled “broad spectrum,” which means it protects against both ultraviolet B (UVB) and ultraviolet A (UVA) rays. Zinc oxide and titanium dioxide sunscreens are good to use on particularly sensitive spots, such as the nose and lips.

The AAP and American Academy of Dermatology recommend an SPF of at least 15, but many experts recommend SPF 30 or higher for babies, and many baby sunscreen formulas have even higher SPFs. If possible, apply sunscreen 30 minutes before sun exposure and reapply it at least every two hours, especially if your baby has been playing in the water or has been sweating (even if the sunscreen is waterproof).

When trying a new sunscreen, do a patch test on your child’s back to make sure he doesn’t have a reaction to it. If he does develop a rash or redness at the test site, choose a hypoallergenic formula instead.

Why Natural and Organic Sunblock Is Better

There are toxins all around us in the world today. People are becoming more and more conscious of where they go, what they eat, and the things they are exposed to. The rage over organic and natural products isn’t really a rage. People are simply learning that using synthetic chemicals will probably result in our bodies absorbing elements we weren’t supposed to absorb. Learning how our bodies work and why we should avoid certain synthetic ingredients will help promote overall well-being and a more healthy society.Skin is our first barrier of defense from the outside world not to mention the largest organ of our body. It is made up of several layers (dermis, epidermis, and subcutaneous tissue). These layers work together by utilizing different types of cells, which create a semi-waterproof layer of tissues highly concentrated with blood vessels. This simple factor allows us to release and absorb substances to regulate our bodies based on the environment we are exposed to.

This is the key to understanding why using organic and natural products is so significant. The types of ingredients skin care products are made up of will dictate what becomes absorbed quickly, what won’t be absorbed and what may clog the absorption process. Most essential oils have a relatively small molecular mass so they are absorbed quickly. However many synthetic ingredients also have a small molecular mass meaning they will be absorbed into the skin and blood stream right away also. As for some of the heavier oils like almond, olive, and coconut oil which make up the majority of crèmes and lotions, they are higher in molecular mass resulting in a slower absorption rate which it ultimately leaves your skin feeling soft and lubricated several hours after the application. Some ingredients like Zinc are not absorbed at all and will sit on top of the skin and act as a physical barrier.

It is important to understand how our skin works and why using natural products will help us in the long run. The more natural and organic a lotion or crème is the more our bodies will be able to absorb and break down the ingredients for overall use in a natural way. Ultimately, preventing synthetic substances from entering our blood stream will help to prevent unwanted chemical reactions commonly associated with toxins.
