Sun protection has become a very important factor in skin care as it can protect from the damaging effects of the UV rays. Find out how sunscreen works and how to use it to fully protect the skin.
Sunscreen is very important for people because it protects the skin
against the dangers of ultraviolet rays from sun exposure. The UV
rays are becoming more powerful because of the thinning of the
ozone layer. The ozone layer protects and limits the entry of the
UV rays so if the ozone layer is thinner, more rays can penetrate
the protective layer.
Sun exposure can cause sunburns, aged skin, age spots, freckles and
wrinkles. Sunburns are very dangerous because they can cause skin
cancer development. Sun protection is meant to diminish the risk of
these damaging effects of sun exposure.
People get sunburned at different rates, depending on the quantity
of melanin pigment in the skin. The darker the skin, the longer it
takes for it to get sunburned. Some medication can also make the
skin more sensitive and more likely to get sunburned.
Just because people need different types of sun protection,
sunscreen manufactures produced sun protection creams with
different protection levels.
The number written on the sunscreen indicates the number of
protection. The higher the number the longer your skin will be
protected. To find out what type of level of protection you need
multiply the number of minutes it takes for you to get sunburned
with the number written on the sunscreen ant the result will
indicate the number of minutes the sunscreen will offer you
protection.
It is important to use sunscreens which protect you from both types
of ultraviolet rays, UV-A and UV-B. There are certain sunscreens
which only offer protection against only one type of UV rays, so
buy a sunscreen which is “broad spectrum” which means it protects
against both types of UV rays.
Sunscreen works on protecting your skin by absorbing the UV rays
and transforming them into heat. The ingredients contained in the
sunscreen will create the whole process. They don't allow the rays
to penetrate the skin, thus aiding in protection.
Sunblocks contain ingredients like zinc oxide or titanium oxide
which can help reflect or scatter the UV rays.
Even though sunscreens contain a lot of chemical ingredients they
are not dangerous for our skin they are actually meant to protect
it. It is important to wear sunscreen even when it is cloudy
outside because the UV rays can penetrate the clouds as well.
Wear sunscreen for your health as well as the health and appearance
of your skin.
