Normal skin contains cells called
melanocytes. These cells produce Melanin,
the substance that gives skin its color.
Skin
with too much melanin is called hyperpigmented skin.
Skin
with too little melanin is called hypopigmented skin.
Pale skin areas are due to too little
melanin or underactive melanocytes. Darker areas of skin (or an area that tans
more easily) occurs when you have more melanin or overactive melanocytes.
Bronzing
of the skin may sometimes be mistaken for a suntan. This skin discoloration
often develops slowly, starting at the elbows, knuckles, and knees and
spreading from there. Bronzing may also be seen on the soles of the feet and
the palms of the hands. The bronze color can range from light to dark (in
fair-skinned people) with the degree of darkness due to the underlying cause.
