Pigmentation refers to the natural color of the skin, hair, and eyes, which is determined by the amount and type of melanin produced by melanocytes in the skin. Pigmentation can be affected by various factors, including genetics, sun exposure, and age. Pigmentation can also be altered using cosmetic products, such as skin-lightening products, which are used to reduce the appearance of dark spots or uneven skin tone.
