Skin cancer is an increasingly common disease that is thought to be caused by over exposure to Ultraviolet (UV) radiation. This combined with certain genetic predispositions, like fair skin, can make a person particularly vulnerable to developing skin cancer. Most people get exposed to UV radiation from spending time in the Sun. As it is practically impossible to avoid being in the Sun, minimizing the amount of time spent in the Sun or limiting it's impact on the skin is often advised. This article will cover some of the ways to protect yourself from the damaging affect of the Sun. It concentrates on how sunscreen can protect you from developing skin cancer.

Before covering how sunscreen works, it should be reiterated that sunscreen is not the only way to protect your skin from the sun. It should be used in conjunction with some of the ideas covered below.

Avoid going out in the Sun when it is strongest. This means from around 11 in the morning through to 3 in the afternoon. Naturally, mid days is the worst time to be out in the Sun. Granted, this may not always be possible, especially if you work outdoors or leave the office for lunch. In this case take other precautions.

Wear clothing that can protect your skin form sunlight. Darker colored clothing works better than lighter colors. cover your arms and legs if practical or comfortable.

Always wear a hat in the Sun. A hat with a wide brim will protect your face and scalp from UV rays. Some people use a sun umbrella to protect themselves too.

Wear sunglasses that absorb UVA and UVB radiation, as they can damage the eyes. Not only can they cause melanoma developing but they can lead to cataracts and other diseases.

After you have done these things you should then consider wearing sunscreen. Cover the parts of your body that are not covered by clothing. Some advise to cover the arms and legs with sunscreen even if they are covered by clothings as you might roll up your sleeves and it doubles the protection.

Sunscreen comes in two forms. There is chemical sunscreens that absorb UV rays and physical sunscreens that reflect the UV rays (sometimes referred to as sun blocks).

The sun protection factor (SPF) of a sunscreen is often used to illustrate it's strength and effectiveness. Most advice suggests that you use a sunscreen with an SPF of 30+. However the SPF of a sunscreen only applies to UVB radiation. Although this is thought to be the worst form of radiation for skin cancer, recent research suggest that UVA radiation can be just as bad. If you want a sunscreen that protects against both UVB and UVA radiation then you should look at what is marketed as broad spectrum sunscreen.

Sunscreens that act as a sun block are particularly useful if you work outdoors or spend plenty of time in the Sun. They are a thick cream that provides a barrier to the sunlight. People often put them on sensitive parts of the body like the lips and nose.

Sunblocks normally consist of titanium dioxide or zinc oxide. If you don't like the prospect of having a large white band across your nose then an alternative is to get ultramicronized titanium or zinc sunscreens. They do the same job of reflecting the sunlight but do make you look like you have warpaint on.

Regardless of the type of sunscreen you go for, remember to always reapply it every 2 hours. This may vary depending on how active you are in the Sun. Get a cream that you like in terms of texture or fragrance so that the reapplication is not such a chore.
