Detailed explanation-1: -Both carotenoid pigments and melanin increase skin yellowness but melanin additionally decreases skin lightness (L∗) whereas carotenoids have little effect on L∗ (Alaluf et al., 2002; Stamatas et al., 2004).
Detailed explanation-2: -Carotene is a yellow-orange pigment found in carrots. Your skin may turn this color if you eat a lot of carotene-rich foods. The skin may turn yellow due to another factor, called icterus or jaundice, which occurs with serious liver disease.
Detailed explanation-3: -The primary light absorbers in skin are hemoglobin and melanin. Most of scattering is attributed to collagen fibers and in pigmented skin to melanosomes. Traditionally skin redness is considered to arise due to locally elevated concentrations of hemoglobin, whereas skin pigmentation is attributed to melanin.
