February 5, 2010
It is very important for an individual to guard the skin against the harmful rays of the sun. The sun produces ultra violet rays which are very harmful for the skin of an individual. Sun screen is a very important product that helps to protect the skin of an individual from the harmful sun’s rays.
Ozone layer is depleting day by day, thus making the ultra violet rays of the sun more powerful. The skin of an individual is impacted in a great way due to the harmful rays of the sun. The skin may get damaged due to exposure of the sun. Exposure of the sun may lead to aging spots on the skin, sunburns, wrinkles and freckles.
There may be risk of skin cancer due to the sunburns. It is very important for an individual to protect the skin from the exposure of the sun in order to guard against the above said harmful impacts of exposure of the skin to sun.
Application of sunscreen on the skin before going out in the sun is a very good way to protect the skin from sun’s exposure. Sun screens are available in various protection levels. While choosing the sunscreen it is very important for an individual to determine his or her skin type.
The impact of sunburns may differ from one individual to another. It entirely depends on the amount of melanin present in skin. Melanin is a pigment that provides color to the skin. Dark skin takes longer time to get tanned due to exposure of the sun. Therefore, it is important to choose the sunscreen according to your skin level.
Sunscreens are available with various numbers written on them. The greater the number written on the sunscreen, the longer would be the protection that would be granted to the skin. Choose the sunscreen, which offers protection against both UV-A & UV-B rays of the sun.
Sunscreens with broad spectrum should be bought as against sunscreens which offer protection from only one form of ultra violet rays. The ultra violet rays of the sun are absorbed by the sunscreens and transformed into heat. The ingredients of the sunscreen help in preventing the penetration of the sun’s rays in the skin, thus protecting the skin from the UV rays.
