It is said that skin is
the mirror of our inner body. If the body functions well, the skin will look
radiant and remain healthy, while if the body is not functioning the right way,
the skin will not look good either. Yet, in time, because of internal or external
factors the skin becomes spotted and loses its moisture as well as that radiant
appearance. In order to know what it is going on with it and why these things
happen, it is necessary to know some basic things about skin color and the main
components of it.
Factors That Determine Skin Color
There are three main
factors which contribute in one way or another, to the actual skin color of an
individual. The first one is the melanin, the substance which gives
the dark color, the second is the carotene which is responsible for the yellowish tint. The last, but not least includes the blood vessels which give the skin that pink nuance.

Melanin is produced by
the melanocytes and it is triggered by the enzyme responsible for coloring the
hair, the eyes and the skin. This enzyme is called tyrosinase. The greater the production of melanin is the
darker the skin color will be.
In addition to influencing the color of the
skin, melanin has also the role of absorbing the solar rays and protecting
the body from the invasive effects of the ultraviolet rays. For an effective
protection, the amount of melanin increases when the skin is exposed to sun.
This is the time when the tan skin appears. However, when the melanin is no
longer capable of absorbing the solar rays, the sunburns appear. Mild sunburns
usually do not have any long term effects on the skin, as the damaged layers of
skin are regenerated and new and healthy skin replaces the damaged ones. Yet,
severe sunburns may result in scars and most often in dark patches of skin and
brown spots which may remain on the skin for the entire life.
Melanin is present in larger quantities in people with dark skin and in
lesser quantities in people with light skin. Thus, those people having light
skin are more prone to sun burns and dark spots caused by the sun than those
with dark skin.

But not only sun can increase the amount of melanin from the skin. Hormonal
imbalances, external factors, such as pollution, wounds and rashes can also
increase the amount of melanin from certain portions of the skin, thus making
it darker and anesthetic.
