Pigmentation, also known as hyperpigmentation, is a skin condition characterized by the appearance of dark spots, patches, or uneven skin tone on the face, hands, and other areas of the body. The causes of pigmentation can include sun exposure, hormonal changes, genetics, and certain skincare products. To treat pigmentation, there are several options available such as topical treatments, chemical peels, laser therapy, and prevention methods like protecting the skin from sun exposure, avoiding certain skincare products and following a healthy diet. It's important to note that for any treatment, it's always best to consult with a dermatologist for personalized advice and treatment. - Jagriti Choudhary
