Darkened skin, or hyperpigmentation, is the appearance of patches of skin that become darker than the surrounding area.
In fact, sun exposure is one of the most common causes of darkened skin.
Energy from the ultraviolet rays of the sun is absorbed by melanin as a normal way to protect the skin from overexposure.
Why is my skin color getting darker?
Your skin gets its color from a pigment called melanin. If your body makes too much melanin, your skin gets darker. Pregnancy, Addison’s disease, and sun exposure all can make your skin darker. If your body makes too little melanin, your skin gets lighter.
Why is my skin getting darker as I age?
As we age, melanin-synthesizing cells known as melanocytes become victim to excess sun exposure, inflammation, free radicals, and hormonal changes. As we age, this process becomes dysregulated, causing the skin’s outward appearance to develop unsightly dark spots and uneven areas of hyperpigmentation.
What disease causes darkening of the skin?
Noticeable darkening of creases in the skin, sun-exposed areas, joints, and old scars could be a sign of adrenal disease, such as Addison’s disease. Bronzing of the skin in a patient with diabetes can be a sign of an inherited defect in iron metabolism that leads to liver failure known as hemochromatosis.
