Facts about our Skin

Our skin contributes 15% of our body weight.

A person’s skin can easily cover an area of 2 meter square.

We have about 21 sq ft of skin, about 17 km of blood vessels.

We have about 300 million skin cells. A single square inch of skin has about 19 million cells and up to 300 sweat glands.

Our skin is its thickest on your feet (1.4mm) and thinnest on your eyelids (0.2mm).

The skin renews itself every 28 days.

Our skin constantly sheds dead cells, about 30,000 to 40,000 cells every minute!

More than half of the dust in your home is dead skin.

Dead skin easily is about a billion tons of dust; in the earth’s atmosphere.

Our skin is home to more than 1,000 species of bacteria.

Skin that is severely damaged may try to heal itself by forming scar tissue, which is different from normal skin tissue because it lacks hair and sweat glands.

Skin can form additional thickness and toughness — a callus — if exposed to repeated friction or pressure.

Some of the nerves in our skin are connected to muscles instead of the brain, sending signals (through the spinal cord) to react more quickly to heat, pain, etc.

Our skin has at least five different types of receptors that respond to pain and touch.
