The Importance of Skin’s Epidermis

Skin’s epidermis is crucial to human survival as it forms a protective barrier that keeps the body hydrated, shields it from the outside world, and holds keratinocyte-rich layers. The dermis beneath the epidermis is packed with crucial nerve, lymph, and blood vessels that hold sweat glands, hair follicles, and oil glands to maintain skin nourishment.

Your Personal Microbial Ecosystem

Did you know that the number of organisms you carry within and on your body exceeds the number of cells in your body? You have a unique microbial signature formed through an intimate relationship with archaea microorganisms, microscopic mites, and bacteria. These organisms contribute to regulating skin pH, eat dead skin and sebum, and cause acne. Your microbial makeup is distinct, influenced by age and proximity.

Skin Health and Nutrition

The condition of your gut and digestive health can have a significant impact on the appearance of your skin. Dehydration can lead to reduced skin elasticity, while alcohol abuse has a dramatic effect on skin’s appearance. Consuming high-glycemic-index foods and sugary drinks can cause acne and wrinkles. Conversely, eating colorful fruits and vegetables rich in carotenoids like orange pepper and carrots can provide a healthy, glowing skin.

The Science of Sunlight

The sun’s ultraviolet light reaches our skin, and melanin produced by melanocytes absorbs it. White skin has an SPF of 3, and vitamin D synthesized from sun exposure is vital for regulating minerals in the body. Gain sun exposure for 10-30 minutes, 2-3 times a week, between 11 am-3 pm. Protect against overexposure by wearing sunscreen, sunhat, and seeking shade.

Nourishing Skin and Hair

A diet rich in protein and fruits, especially colorful ones, supports skin and hair health by boosting the immune system and fighting oxidative stress. Smoking breaks down elastin and collagen, and nicotine contracts blood vessels, which reduces oxygen and nutrient supply. Sunscreen and retinoic acid have anti-aging effects, while Botox paralyzes facial muscles to prevent lines.
