What is Hyperpigmentation?

Hyperpigmentation is a commont condition in which some areas of the skin are darker then others. This is due to an  excess of melanin (the brown pigment that determines skin color) in certain areas of the skin. There is a 3 type of hyperpigmentation :

Solar lentigo

This is the term doctors use to refer to ‘age’ or ‘liver’ spots. These are flat, brown spots or freckles and generally appear on skin that has been exposed to the sun. People who sunburn easily are more likely to develop this condition.

Melasma

Melasma is similar in appearance to age spots but appear over larger areas. Melasma can appear on the face, abdomen and other part of the body. It is usually the result of hormonal changes, which is why many pregnant women develop it. Women who are on oral contraceptives can also develop this condition due to the hormonal changes.

Freckles

Freckles are small, circular spots on the skin. They are more common among fair-skinned people, particularly after extended exposure to the sun. They vary in color (yellow, reddish or various shades of brown), depending on the individual and are slightly darker then the rest of the skin.
