Dynamics of epidermal carotenoid levels in vivo of healthy subjects in Antarctica.

Skin carotenoids are essential components of the anti-oxidative protective system of the human skin and are indicator for the overall anti-oxidant status of the organism [1]. Ozone depletion is directly contributing to climate change in the southern hemisphere including Antarctica. Ultraviolet (UV) light, air pollution, lifestyle and diet affect the oxidative stress in the skin. Cold, wintery weather conditions and predispose to development of dermatoses through damage to the skin barrier and enhanced oxidative stress [1-3]. Herein we describe the dynamics of skin carotenoids of healthy volunteers during their 30-day stay at Livingston Island, Antarctic Peninsula.
