Chances are that someone you know is headed back to school, and just because you’re not enrolled doesn’t mean you can’t be a learner for life. If you’re reading this, you’re probably a skincare enthusiast – but just how much do you really know about your skin? We’re making it easy for you to brush up on your knowledge with this list of 10 facts about skin. Without further ado:
The skin is your body’s largest organ. An average adult’s skin spans 21 square feet and weighs nine pounds!
On average, a person’s skin contains more than 11 miles of blood vessels.
The skin emits around a quart of fluid on an average day in the form of sweat. On an exceptionally hot day and with heavy exertion, skin can exude up to three gallons! That’s a good reason to drink plenty of water and stay hydrated.
Your skin sheds 50,000 cells every minute. Worldwide, dead skin accounts for a billion tons of dust in the atmosphere!
Skin helps regulate your body temperature. Sweating helps cool your body when it’s hot. In cold conditions, blood vessels in the skin tighten to limit the amount of warm blood that reaches the skin, preventing heat loss.
Millions of bacteria live on the surface of your skin. Your skin’s surface is host to a diverse community of bacteria, known as the skin microbiota. These are largely harmless and many actually help immune cells fight disease-causing microbes.
Skin color is determined by the pigment melanin. Everyone has the same number of cells that produce melanin, but not everyone’s body produces the same levels – hence, the wide variety of skin tones among people.
Your body regenerates a new layer of skin every 28 days. That said, dulling dead skin cells still remain on the surface, so regular exfoliation with a gentle yet effective product like Actifirm Z-Peel is important.
