Types and Symptoms of Pigmentation
Age spots, also called liver spots or solar lentigines, are brown, tan, or black spots that appear on ones skin with over exposure to the sun. They commonly appear on the face and hands, or on sun-exposed areas of the body. Age spots usually appear on older people or after spending a long time in the sun.
Melasma, also called chloasma or some say "the mask of pregnancy" are large patches of darkened skin, which often appear on the forehead, face, and stomach. Women, people with darker skin and women who are pregnant or taking birth control pills are more likely to develop melasma.
Post-inflammatory hyperpigmentation are spots or patches of darkened skin that appear after an inflammatory skin condition, such as acne or eczema. They usually appear on the face or neck. People can get them when they have had inflammation or an injury to their skin.
A big cause of hyperpigmentation is: Sun exposure
The body produces more melanin to protect the skin from lengthly exposure to the sun. This can cause dark spots or patches on ones skin.
