When you've got darker patches of skin, then you've got hyperpigmentation that's the result of the overproduction of saliva inside the skin tissues in that region. Melanin is the compound inside the body that produces browning of the skin.
Suntans, your body's way of defense if exposed to the sun's rays, are a consequence of increased melanin production. The stains that form on elderly skin often referred to as liver or age spots, are extremely hyperpigmentation from sunlight damage and generally on the face and hands. While hyperpigmentation is a lot more evident , it occurs in all races.
Scarring because of abrasion, acne, burns, and other items could lead to hyperpigmentation treatment too. Surgeries can also make it. Remember that not every injury to the epidermis or operation will cause hyperpigmentation.
Genetics may also be an element in hyperpigmentation. The apparent indications of that are freckles. These are influenced by both genetics and other resources .
When genetics is combined with a different element that is a known cause for hyperpigmentation, there's generally an increase in the magnitude of these freckles and they'll become darker. When the excess source is eliminated, the freckles often return to the normal amount and color.
Another sort of hyperpigmentation you might have heard of is that the mask of pregnancy that's triggered by the hormonal changes that women experience with pregnancy. This is most frequently located on the face but may show up on the abdomen too.
Contraceptive pills and other hormonal birth control techniques create the body to mimic pregnancy and may also lead to this kind of hyperpigmentation. Normally this hyperpigmentation goes away following the hormones can resume their regular levels, which can be after pregnancy or following quitting birth control pills.
