There are many things we consider
invasive for our skin: chemical products, pollution, stress and even aging are
on our list when it comes to things which will badly affect the texture and
color of the skin. However, what many people tend to ignore when it comes to
their skin is the harmful effect of the sun.
Sun is one of the worst enemies the
human skin could have. First of all because there are very few ways in which we
can stay out of its way. Everywhere we go we have to meet the dangerous sun
rays, especially during the hot days of summer. Because we got so used with it,
sun no longer is seen as a threat. Moreover, there are people who benevolently
expose their skin to the powerful sun rays without any protection, thus
damaging their skin willingly.
But why is sun a threat to human skin
after all? Well, the ultraviolet rays which come from the sun are the ones
which affect the skin. People with lighter color of skin feel the solar attacks
more acutely than people with darker types of skin. This is mainly because of a
component of skin called melanin. Melanin is the substance responsible with the
color of the human skin. The more melanin your skin produces, the darker it
would be. In addition to giving the skin a darker color, the melanin is also
responsible with absorbing and neutralizing the ultraviolet rays coming from
the sun. Thus, people with darker skin have more melanin in the composition of
the skin, thus are less prone to skin lesions or burns caused by the sun rays.
On the other hand, people with lighter skin lack the necessary amount of
melanin which can effectively combat the sun rays, thus are more susceptible to
burns and skin damages cause by sun.
When the skin is exposed to the sun,
more melanin is produced, so the skin gets darker. We call that a suntan. This
suntan can become dangerous when the skin is no longer able to produce enough
melanin to protect the skin, thus the skin starts to get burned. The reason for
which the tan is not permanent is because in time, the cells containing a greater
amount of melanin than normal are pushed at the surface where they are
discarded, thus leaving room for a new and healthy layer of skin. However,
there are times when the skin can be so affected that it would not recover in
time, brown spots and darker patches remaining in place forever. In addition to
that, skin cancers and other skin diseases can appear because of excessive
exposure to sun.
This is why it is necessary to take
safety measures each time you go out of the house, use sunscreen whenever it is
necessary and limit the time you stay in the sun as much as possible. This way
you will also limit the side effects you could experience because of the sun.
Protecting your skin from the invasive sunrays means protecting your health, so
do not overlook this aspect when getting out of the house.
