Carotene is the pigment responsible for the yellow color in the skin. It is a type of hydrophobic pigment found in various fruits and vegetables, such as carrots and sweet potatoes, which imparts an orange or yellow hue. When consumed, carotene is deposited in the skin, contributing to a yellowish tint, especially in individuals with lighter skin tones or those who consume high amounts of carotene-rich foods.

Melanin, while also present in the skin, primarily contributes to brown and black pigmentation. Hemoglobin is the pigment in red blood cells responsible for transporting oxygen and gives blood its red color; it is not directly involved in skin pigmentation. Chlorophyll, found in plants, is responsible for the green color, which is not related to human skin pigmentation.

Understanding the role of carotene can be crucial for professionals in the cosmetic and dermatological fields, particularly when considering factors such as dietary intake and skin appearance.
