Why Use Sunblock In The Winter

According to the American Cancer Society, one in five Americans will develop skin cancer in their lifetime. So it is vital that one learns the potential risks and the preventative solutions associated with skin cancer.
The first thing to know is that the skin does not repair itself as fast as it used to with age. Two, that sun exposure increases the damage and affects the health and beauty of your skin. This can be verified by a simple observation. Compare the sun exposed skin to areas of your body that are normally covered, and you will see a difference between the two, in color and texture. And as you can see, sunscreen is an anti-aging essential.
The Two Culprits: UVA (ultraviolet-A) AND UVB (ultraviolet-B)
The fundamental difference between these two rays is that one has a longer wavelength, UVA, and therefore can penetrate deeper into the skin. UVA are the aging rays, and according to research is the leading cause behind your skin wrinkling, leathering and other aspects of photo-aging. UVA is also present all year round and is as penetrating at 9AM mid December as it is at 3PM in July.
UVA is also less likely to cause sunburn but works to increase UVB’s cancer causing effects and according to some dermatologist may directly cause some types of skin cancer.
UVB has a shorter wavelength and is the ray that causes suntans and is also the ray that produces sunburn if you overexpose yourself to the sun. These UVB rays penetrate the top surface of the skin and causes it to produce more melanin or more color, in essence the suntan. And over time continual exposure to the sun, UVB rays, damages the skin, producing what we call liver spots or age spot.
However, UVB because of its shorter wavelength, is less likely to cause injury during the winter months, when the Earth is slightly tilted away from the Sun and therefore cannot reach the Earth’s surface.
Sunblocks And Sunscreens:
Just like there is a difference between UVA and UVB rays there is a basic difference between sunscreen and sunblock. Knowing this essential difference can help you in choosing the best in sun protection.
Sunscreens chemically absorb UV rays, while sunblocks physically deflect them.
Sunscreen has effectively blocked UVB effectively, but until recently it provided less UVA protection. And although the technology has advanced and new products have some new and revolutionary chemicals that work well against all UVA wavelengths, mineral based sunblocks are preferred.
Mineral based sunblocks seem to be the more natural and the “organic” choice in sun protection. New preparations such as micronized titanium dioxide, zinc oxide, used in sunblock to prevent or treat minor skin burns and irritation, and iron oxide are used to successfully reflect (bounce away) the harmful effects of both UVA and UVB rays.
And when these minerals are used in conjunction with multiple antioxidants, you have a unique product that counteracts free-radical damage and increases protection against UV rays. Joanna Vargas Skin Care salon carries “Solar Protection Formula”. It is a unique solar protection product that is highly effective and is used as a preventative measure for maintaining the health and beauty of your skin.
