12 Skin Facts You Probably Didn’t Know
Our skin is an amazing multi-tasker; it protects other organs, shed cells and keeps you cool or warm. But other than the fact that you should protect your skin from the sun, how much do you really know about it? Here we summarized some fascinating facts about your skin. The skin…
1. Is the body’s largest organ: The skin has a surface area of approximately 22 square feet. The second-largest organ in the body is the liver.
2. Has different thickness: The eyelids have the thinnest skin — at 0.05 millimeters — while the palms and soles of the feet have the thickest skin, at 1.5 millimeters.
3. Is heavy: About 16 percent of your overall body weight is from your skin alone.
4. Is made up of several layers: The epidermis, the dermis and the subcutis. The subcutis is the innermost layer and is made up of fat and collagen cells. The dermis is the middle layer and is responsible for 90 percent of skin’s thickness. The epidermis is the outermost layer and serves as a protective barrier between the body and the environment.
5. Sheds cells every minute: You lose 30,000 to 40,000 skin cells a minute!
6. Helps your body maintain temperature control: When you are over-heated blood vessels widen so that heat can be released easily through the skin. When your body is cold, the blood vessels in the skin constrict.
7. Had a different color when you were born: Healthy newborn baby skin is actually a deep red or purplish color and hands and feet are a blueish hue.
8. Acne is the most common skin condition in the U.S.: More than 85 percent of people will experience it at least once in their lives, affecting 40 to 50 million Americans.
9. Acne affects babies too (well, kind of): This acne is caused by the mother’s hormones that are still in the baby’s blood.
10. Scars are caused by damage to the second layer of skin, the dermis: Scar collagen is different from collagen in normal skin. As such, even when skin cells die and are replaced, scar collagen is not shed. Scar tissue does not grow hair.
11. The way you sleep can affect your skin: Sleeping with your face buried in your pillow can lead to wrinkles.
12. Babies’ skin is covered with a waxy substance: Called vernix, this film protects the fetus’s skin in the womb. It usually washes off with the baby’s first bath.
