13 things you didn't know about your own skin

1. Your skin is the largest organ in your body. Its area is approximately 2 square meters.

2. Skin care product can enter the bloodstream in 26 seconds.

3. Skin weighs a lot. Nearly 16% of your body weight.

5. Almost forty thousand dead skin cells fall off of you every minute.

6. Your skin is a different color at birth. Even in characteristically colored races, including the Negroid, children are born lighter than adults and darker in the first few days after birth, when the blood circulation brings the skin the necessary pigments.

7. Scars occur when the middle layer of the skin is damaged. Collagen from the subcutaneous layer in this case acts as a repair agent. 7 do's for dry skin.

8. On a hot day, you can sweat up to 13 liters of fluid. The only places on a person that never sweat are the base of the nails, the lips, the eardrums and the tip of the penis.

9. The pattern on the fingertips - the same prints that everyone has - serve to increase friction and reliable grip. Each of us is a little Spider-Man.

10. Humanity was originally black. And only about 50,000 years ago, during migration to northern latitudes, the level of melanin pigment was evolutionarily reduced.

11. The thinnest skin on your eyelids is less than 0.05 mm, and the thickest on the soles of your feet can be as much as 3 mm thick.

12. The skin regulates body temperature. In hot weather, in addition to perspiration, blood vessels dilate and heat is transferred outward directly through the skin. In the cold, on the contrary, they narrow.

13. As we age, the skin becomes thinner and drier and loses its elasticity. Actually, this is why wrinkles appear.
