What Is In Sunscreen And How Does It Protect Your Skin
Skin Cancer is a common disease that is thought to develop when the skin is exposed to ultraviolet rays. Depending on the type of skin, this exposure can be limited and still lead to the development of some form of skin cancer. Fair skin that burns easily in the Sun is particularly vulnerable. As the Sun is the leading source of Ultraviolet (UV) radiation that people are regularly exposed to it is important to protect yourself when in the Sun. This article will list the common methods that can help prevent skin cancer. It will concentrate on Sunscreen and how it works to protect your skin.
The first thing to point out is that sunscreen should never be seen as the only thing you can do to limit your exposure to sunlight. It should be used in conjunction with some of the points mentioned below.
The best way to avoid UV radiation over exposure is to avoid sunlight when it is at it's strongest. Unsurprisingly, this is the period when it is at it's highest point in the sky, around mid day. Twelve noon is the worst time and the few hours around this time are also bad. Stay out of the sun during these times. If this cannot be done then take precautions.
Wear protective clothing. Darker colored garments are better than lighter ones. Cover your arms with a long sleeve shirt. Cover your legs with long pants or socks.
Wear a hat when in the sun. This will protect your scalp, face and eyes from UV rays. A wide brimmed hat is best as it provides more protection. Other people use a sun umbrella but a hat is better.
Wear a good pair of sunglasses, as skin cancer can also affect the eyes.
After taking all these precautions you should then apply sunscreen. Cover parts of your body that are not protected by clothing and come into direct contact with the sunlight.
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).
A way to determine the effectiveness of a sunscreen is to look at it's Sun Protection Factor (SPF). The popular recommendation in this respect is to always go for an SPF of 30+. SPF pertains to the ability to protect the skin from UVB radiation that is thought to be the worst form of radiation for sun burn and skin cancer. However, it does not protect against UVA radiation, which researchers feel can be just as dangerous as UVB. Products that are known as Broad Spectrum sunscreens protect against both UVB and UVA rays.
Sunscreens that act as a sunblock are best if you have to spend plenty of time out in the Sun. No doubt you have seen people wearing such creams on the nose or lips. It is almost like a paint that they have applied to the skin. This puts many people off using such creams but they are the best way to protect your skin from the Sun.
Sunblock sunscreen will have either titanium dioxide or zinc oxide in them (they are also sometimes referred to as zinc cream). If you don't appreciate having a large band of zinc cream across your nose then an alternative is ultramicronized titanium or zinc sunscreens. They are transparent but do the same job of reflecting UV rays.
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.
