THE OUTER SKIN: EPIDERMIS
It’s the thin, visible part of the skin. It includes the outer layers and the barrier. The outer skin informs and protects the body in regards to diseases, temperature changes, and physical impacts. Since it is made of dead skin cells wrapped in lipids and held together by a waxy substance called sebum, it doesn’t need any nourishment from the body. Hence there are no blood vessels in the outer skin and you won’t bleed when you scratch it.

NMF is part of skin’s natural climate IQ and recent studies have confirmed it components change to adjust to a climate.
