Its integrity and resilience are a direct reflection of its intricate, multi-layered structure, which consists of three primary layers: the epidermis, the dermis, and the hypodermis. Each layer is composed of specialized cells and tissues that perform distinct functions, and the changes that occur in these layers over time are the biological basis for the visible signs of aging. The outermost layer, the epidermis , serves as the body’s first line of defense, a crucial barrier that prevents the invasion of substances from the outside world. It is a thin layer, often compared to the thickness of a piece of paper, and is composed primarily of keratinocytes, which are the principal cells of the epi...

    This is the over-view audio of this article. Make sure to play it and read it Chapter 1: The Essential Foundation: What Are Vitamins and Minerals?   The discussion of nutrition often centers on the macronutrients—proteins, carbohydrates, and fats—but the foundational building blocks of human health are the micronutrients. These are the vitamins and minerals that, despite being required in only tiny quantities, orchestrate the vast network of biochemical processes essential for life. Vitamins are a heterogeneous group of organic substances, while minerals are inorganic elements that exist freely or bound in salts. 1 A critical distinction between the two is their response to environmental factors like heat: vitamins, being organic compounds, can be altered or destroyed by cooking or heating, whereas minerals, as inorganic elements, are not susceptible to this degradation. 1 This inherent difference underscores the importance of a varied and balanced diet that...
