Any extra beta-carotene is then either stored in the liver and fat tissue, excreted through poo, or removed via sweat glands in the outer layer of the skin. This is when the orange skin “tan” can happen. In medicine, this is called carotenoderma.

Carotenoderma gives your skin a yellow/orange pigment that is not the same colour you’d turn from a sun tan. It is concentrated in the palms of the hands, the soles of the feet and smile lines near the nose.
