The skin is the largest organ in the body, covering total area of nearly 20 square feet. The skin offers protection from microbes and elements, regulates body temperature and permits the sense of touch, heat and cold. As we age a number of changes occur to our skin. These changes are due in large part tour diet and exposure to environmental conditions (UV light, wind, toxins, topical chemicals, etc.).
Healthy skin at its core has numerous structural components that define the function of the skin. However, aging, poor diet and environmental factors can cause key structural components of the skin to become compromised. This negatively impacts the appearance of our skin.Targeted nutritional supplementation can supply one of the key pillars of healthy and youthful skin.
The 3 Layers of the Skin
- Epidermis – The outermost layer of skin. It provides a waterproof barrier and creates our skin tone.
- Dermis – Lies beneath the epidermis. IT contains tough, connective tissues, hair follicles and sweat glands.
- Hypodermis – A deeper subcutaneous tissue made of fat and connective tissue.
Structural Components of your skin
Ceramide is the main component of the stratum corneum of the epidermis layer of skin. Together with cholesterol and fatty acids, ceramide creates a water-impermeable, protective organ to prevent excessive water loss due to evaporation as well as a barrier against the entry of microorganisms. As we age, there is a declining amount of ceramide and cholesterol in the stratum corneum of humans.
