Why are carotenoids found in our skin and why is the palm of our hand the site of action?
A. Carotenoids are absorbed with the aid of dietary fat. Thus they are found predominately in the “fatty” areas of the body, including your skin. The fatty tissue in our palm is a prime area for testing because it is easily accessible has a relatively high carotenoid content due to the higher amount of fatty tissue, and there is a minimal difference in skin pigmentation between subjects in this tissue area.
