About Repelling Sunshine Killer

UV rays are all around us. Even if you do not step out of your house, your skin will still be subjected to damage caused by UV rays from the sun. A dermatological report from USApointed out that the damage UV rays cause to the skin is accumulative. For sceptics, just look at the vast difference between the skin on your inner arm and outer arm. This is the evidence of solar-induced damage.

UV rays can be divided into three types, according to their wavelengths. There are UV-C (200-280nm), UV-B (280-320nm) and UV-A (320-400nm). The shorter the wavelength, the stronger the impact on the skin. Fortunately, the shortest UVC is already absorbed by the ozone layer before it can reach the earth surface. However, both UVB and UVA can reach to the ground level to inflict direct damage on the skin.

UVA can penetrate the dermis layer of the skin to damage the elastic fibre and collagen fibre, making skin lose its elasticity. At the same time, it darkens the epidermis layer, inflicting the greatest damage on skin. Unstoppable by umbrellas and indoor protection, its effects rage unbridled even on cloudy days.

UVB is the main culprit for those unsightly spots. It stimulates the epidermis, activates the self-protecting mechanism, accelerates melanin formation, darkens the skin and causes a surge of wrinkles.

The latest scientific research has proven that the skin cells will suffer irreparable damage when exposed with no protection to the sun, even if it is only for a day. Furthermore, 90% of skin problems are caused by UV rays.

All-Pervading UV Rays

To resist the damage caused by UV rays, it is vital to first develop a correct understanding. Many think that umbrellas and hats can easily replace sunblock products in preventing UV rays. This could not be further from the truth. Umbrellas, hats or long-sleeved shirts can only block the sunlight; they are unable to keep out UV rays. This is the case even at seaside and beaches.

To step up on sun protection, try to avoid exposure to the sun between 11amand 3pm, for this is when UV rays are the strongest and most damaging. However, sun protection should not be carried out only when there is intense sunlight, as UV rays are all-pervading, regardless of seasons, weather or location (indoors and outdoors). UVA can penetrate deep into the dermis layer even if UVB is blocked by the clouds. So do not be deceived and think that UV rays are absent during cloudy days, as this would lead to negligence in preventing the damage caused by UV rays.
