Freckles may be described as flat, round, dark colored spots
that range in size from about 2mm to 4mm. Freckles could be the result of
pigment precipitation in one particular place, as generally the skin
surrounding the spot is lighter in color. Freckles have a hereditary aspect to
it and you are likely to inherit it if runs in your family. Freckles are
usually of no medical consequence and do not cause any problems. Freckles are
sensitive to the UV rays of sunlight and hence appear more prominent during or
after exposure to sunlight. Though freckles could be present all over the body,
mostly they are found in areas exposed to sun.
There are two basic types of freckle:
Ephelides -
These are flat red or light-brown spots that
typically appear during the summer months and fade away in the winter. These
types of freckles could be hereditary.
Lentigines -
Lentigines may be small tan, brown or black
spot that is darker than an ephelide. This does not fade in winter. This is
also a genetic condition.
Rare disorders such as XerodermaPigmentosum cause an
increased sensitivity to ultraviolet rays leading to freckles. Prolonged
exposure to sunlight can cause freckles to appear, more so in case of
fair-skinned people. The melanin content is less in case of fair-skinned
people; hence exposure to sunlight causes these spots to appear. Hormonal
imbalance could cause freckles too. In this case, the estrogen could
over-stimulate pigment producing cells causing them to generate more color when
exposed to sunlight. Regular use of fruit and vegetable masks such as those
made with apricots, strawberries, cucumbers and red currant will help lighten
freckles.
