Our skin constantly repairs and rejuvenates itself to avoid damage.
If we always tend to get sunburn instead of a tan, the sun will cause an inflammation in our skin within one hour of sun exposure.
The epidermis of a sun-exposed skin is essentially twenty times thicker than that of a sun-protected skin.
Humans are born with strong skin cells that divide regularly and adhere to one another, covering our bodies. However, our skin is not just a protective surface - it is a functional organ that regulates our body temperature, transmits senses and has a defensive effect, creating a pigmentation to protect sensitive genetic material from radiation. Some of its cells are like soldiers that guard against invaders and, when necessary, alert other cells to release antibodies, and to activate the body's immune system.
The more the skin performs its functions, the more it supports itself. Sebaceous glands secrete sebum to keep it oily, while an internal hydration system balances the moisture levels. The skin constantly rejuvenates and renews itself, so as to avoid damage. It releases natural antioxidants to suppress free radicals and degrades nutrients to essential molecules, giving each cell exactly what it needs.
