Over the course of my decades of medical training, study, and continued reading to keep up in this ever-changing field of medicine, I have come across multiple pieces of trivia (or factoids) that are of interest related to the skin. I have been collecting them for some time and have been wondering how exactly to present them in this blog.
Finally, I decided that I would put them in a list. Read on and enjoy these interesting facts about the skin. You may even amaze your friends and family with your newly found knowledge:
- Skin As An Organ– Yes, your skin is an organ in the same way that your liver or your heart is an organ. It is in fact the largest organ in the human body, and it acts as the first line of physical defense between your internal body and the outside world.
- Skin Weight– The total weight of the skin of the average adult is about 6 pounds. To put it in perspective, the average adult brain weighs about 3 pounds.
- Skin Area– The average adult skin surface area is about 21 square feet, which is about the square footage of a small closet.
- Skin Circulation– To feed the surface area and weight of the average adult skin requires over 10 miles of blood vessels.
- Skin Cells– Every square inch of your body surface area contains over 18 million skin cells.
- Skin Cell Turnover– Every minute of every day, your skin loses about 35,000 skin cells. By the end of a calendar year, your skin turns over about 10 pounds of skin on average.
- Skin Conditions– Acne is the most common skin condition in the United States, affecting 40-50 million Americans at any point in time. More than 85% of people will experience acne at some time in their life if they haven’t already.
- Hairless Skin– The only areas of the skin without hair are the palms of the hands, the soles of the feet and the lips.
- Skin Maturation– It takes about 6 months for a baby’s skin to mature into its permanent state of tone and texture.
- Skin Sensitivity– The area of the skin with the most nerve endings is the lips. The lips are actually 200 times more sensitive than the next most sensitive area of the body, the fingertips.
I hope that you found these skin trivia items to be as fascinating as I did. Maybe someday, these tidbits will pay off if you find yourself being a contestant on “Jeopardy” or “Who Wants To Be A Millionaire”.
