The skin is one of man’s most precious jewels. It
makes the individual look in a certain way, it protects the muscles and the
blood vessels from external damage and it increases their resistance through
hard weather conditions. It is the largest organ from the human body, thus taking
proper care of it is essential for those who want to have a normal, healthy
life. However, because skin is at the surface of the human body, the chances of
damage increase significantly.
One of the worst enemies human skin has is the sun.
The ultraviolet rays are very damaging to the skin and can create serious burns
on the surface of the skin. While many people do not get to deal with so
serious consequences on their skin, there are numerous individuals who have to
cope with brown spots resulted from the excessive exposure to sun. These dark
spots appear when the skin is exposed for a larger period of time to the
ultraviolet rays without any type of protection.
The skin color is given by three factors: the
melanin (black color), the carotene (yellow color) and blood vessels (pink
color). The melanin has two roles: that of coloring the skin in black tints and
that of absorbing the ultraviolet rays in order to protect the skin form the
damaging effects of the sun. The more exposed to the sun the skin is the more
melanin will be produced, thus the skin will have a darker color. In some
cases, on some patches of skin, an increased quantity is still produced even
after the skin is no longer exposed to solar rays. On these patches of skin
brown spots are developed.
In order to prevent the apparition of dark spots,
you should not expose your skin to the sun. It is recommended that people with
white or sensitive skin should not get out of the house when the sun rays are
very powerful (in the hot seasons, between 10 am and 4pm) and if they have to
get out they should protect the skin with high SPF lotions. These creams and
ointments are specially designed to reject the solar rays or absorb them before
reaching the inner layers of the skin so that the skin will not be damaged and
the production of melanin will not be increased.
To make sure your skin will not become spotted from
the sun use creams with SPF higher than 30. These will effectively protect your
skin and will allow you to get out of the house even though the sun is burning
outside.
