Pigmentation occurs when melanin, the natural pigment responsible for skin color, is overproduced or unevenly distributed within the skin, resulting in dark spots, patches, or uneven skin tone. This process can be triggered by various factors including sun exposure and UV damage, hormonal changes, acne marks or skin inflammation, and aging combined with environmental stress. Understanding the mechanisms behind melanin production and distribution is essential for developing effective treatment approaches to restore a clearer, brighter, and more even complexion.
