Pigmentation refers to the coloration of skin, hair, or eyes, caused by the presence of pigment. Pigment refers to any substance that imparts color.
The most common pigment that determines skin color is melanin, produced by specialized cells called melanocytes.
Pigmentation can be affected by various factors, including genetics, sun exposure, hormonal changes, and certain medical conditions.
Changes in pigmentation can result in skin discoloration, ranging from lighter or darker patches to splotches or blemishes.
