Skin pigmentation is deposits of melanin that rise to the surface of your skin. It appears as brown spots or blotches on your face, arms, chest, shoulders or other parts of your body.
Age spots, also called liver spots or sun spots, are the most common kind of skin pigmentation. Freckles are another common kind of this. Melasma, which normally appears as a mask covering your cheeks, forehead, and upper lip, is another form of pigmentation
