15 Amazing Facts About Skin You May Never Know

Your skin is, in fact, your body’s largest organ. It helps to protect you from germs and other tiny organisms. It also plays a vital role in protecting us from injury and infection, as well as regulating temperature.

Your skin stores fats, sugars, copper, and calcium to support the healthy functioning of other organs. Every day, your skin may suffer from free radicals that can damage the DNA. Those little cellular mutations cause damage over time, so it’s important to take care of your skin!

To raise your awareness about taking care of your skin health, there are some facts about the skin you should understand. In this article, we will reveal amazing facts about the special body organ to give you more insights and knowledge. From the important role of skin to the unique facts you may never know, we have compiled them all just for you. Without any further ado, let’s check them out!

1. Skin Contributes Up To 15% Of Body Weight

Skin Contributes Up To 15% Of Body Weight

The skin is, in fact, the heaviest organ of the body. Your skin accounts for 15% of your body weight. It is also the largest organ in the body and is composed of minerals, water, protein, and lipids. The average adult has a skin surface area of 20 square feet and a weight range of 6 to 9 pounds.

Not all bodily organs, like the heart or the brain, are internal. This fleshy covering accomplishes much more than just keeping us looking presentable. In fact, without it, we would essentially vanish.

2. Skin Has Approximately 300 Sweat Glands Per Single Square Inch

Skin Has Approximately 300 Sweat Glands Per Single Square Inch

The number of sweat glands per square inch of skin is roughly 300. That is a sizable amount! The number of sweat glands in the skin of a human varies depending on anatomical locations and ranges from 1.6 to 5 million. So it makes sense that people sweat a lot.

Skin Has Approximately 300 Sweat Glands Per Single Square Inch

The average person sweats about 500 CCs per day while at rest. Under conditions of increased activity or warmth, the sympathetic nervous system stimulates the sweat glands to generate more sweat, which can range from 0.7 to 1.5 liters per hour. Sweat evaporates off the skin’s surface, bringing the body temperature back to normal.

3. The Thickest And Thinnest Skin Body Part

The Thickest And Thinnest Skin Body Part

The majority of the body is covered by thin skin, which can vary in thickness. In fact, the eyelids have the thinnest skin. Meanwhile, the palms of the hands and the soles of the feet have the thickest skin. The skin varies in what is present in the layers in addition to thickness. The stratum corneum is a thick layer of dead skin that is present in certain areas and responsible for this arrangement. 

The Thickest And Thinnest Skin Body Part

Although there are many sweat glands in the thick skin area, there are no oil glands or hair follicles. Meanwhile, the rest of the body and areas like the eyelids have thin skin. Although it lacks sweat glands, it is abundant in sebaceous glands and hair follicles.

4. Human Shed 9 Pounds Of Dead Skin Cells Every Year

Human Shed 9 Pounds Of Dead Skin Cells Every Year

The overall number of cells in the human body is around 10 trillion, according to scientists. You have approximately 1.5 trillion skin cells, which account for about 15% of your body weight. Your skin sheds roughly 9 pounds of dead skin cells annually and renews itself every 28 days.

What happens to them all? The majority of the dust that gathers on your tables, TV, windowsills, and those incredibly difficult-to-clean picture frames are, in fact, parts of decomposing human skin cells. In other words, there are remnants of yourself all throughout your home.

5. Your Skin Receptor Is Sensitive To Pain

Your Skin Receptor Is Sensitive To Pain

Sensory receptors that react to pain impulses are all over the skin. The pain receptors, also known as the nociceptors, are sensitive to chemical substances released nearby. Nociceptors have specialized molecular sensors that can recognize dangerous substances and temperatures.

Additionally, mechanical nociceptors are capable of reacting to stimuli that cause tissue damage, such as pinching the skin or overstretching the muscles.

Your Skin Receptor Is Sensitive To Pain

It is common for skin to experience pain in response to intense pressure or heat. Skin that aches to the touch, however, indicates that your brain is responding to stimuli or that your nerves are oversensitive. Numerous pain problems, including migraines, diabetes, shingles, and complex regional pain syndrome, might cause you to be overly sensitive to pain.

6. Color Skin Changing Indicates Health Problems

Color Skin Changing Indicates Health Problems

Changes in your skin may often be a sign of medical illness or changes in your body’s health. Any discoloration of the skin that appears uniform or spotty may signify something. Red, yellow, purple, blue, brown, white, green, and black coloring or tints to the skin are examples of skin color variations. Additionally, skin can get lighter or darker than usual.

Color Skin Changing Indicates Health Problems

A dangerous, potentially fatal illness like an allergic response, an infection, or cancer can result in changes in skin color. Meningitis or allergic purpura, both of which can be fatal, can cause a rash of microscopic purple patches on the skin.

7. The Great Barrier From Outside Germs And Temperature

The Great Barrier From Outside Germs And Temperature

Skin acts as a flexible, airtight, and watertight barrier between the outside world and the body’s tightly controlled systems. Your skin shields your body from potentially harmful microorganisms. The epidermis serves as a barrier of defense that prevent infection-causing bacteria and germs from getting into your body and bloodstream.

The Great Barrier From Outside Germs And Temperature

Meanwhile, skin also plays an important role in thermoregulation. When the body becomes too hot, sweat glands in the skin allow the skin’s surface to cool. The expansion or contraction of heat-conducting blood vessels in the skin also regulates body temperature.

8. Normal Skin Type Is Actually The Rarest

Normal Skin Type Is Actually The Rarest

The normal skin type may be the rarest, according to Dr. Julian of U.S. Dermatology Partners in Austin, Texas. It would probably be more correct to describe the skin type as “balanced.” You should count yourself lucky if you have balanced skin. Skin that is in balance isn’t overly greasy or dry. While you may occasionally experience dryness or oiliness, it’s typically related to environmental elements like temperature, humidity, or the use of a certain product.

In the context of skincare products, it alludes to individuals with minor issues. Therefore, you might need to avoid some products that are labeled for “normal” skin if your skin is sensitive, rosacea-prone, oily, acne-prone, dry, or post-procedure. There is a possibility that the product will make your skin problem worse.

9. The Most Attractive Skin Tone

The Most Attractive Skin Tone

African-American celebrities who attempted to lighten their skin tone have received jeer for it. To darken their skin, however, many Caucasians visit tanning clinics. According to a recent study by Cynthia Frisby of the Missouri School of Journalism, light brown skin is more physically beautiful than pale or dark complexion. Both are drawn to models for advertisements who have a light brown complexions.

Thankfully, research demonstrates that white consumers’ responses to black models in advertisements are almost identical to those of black consumers. No matter if they are tan Caucasians or light-skinned African Americans, it appears that both groups favor the light brown skin tone.

10. Irish Has The Palest Skin In The World

Irish Has The Palest Skin In The World

The Irish, with their light complexion from the country of the Celts, feel the heat and high temperatures the most. But why do Irish people have the world’s fairest skin? In 2016, researchers discovered that the complexion of our light skin comes exclusively from one individual who lived thousands of years ago.

SLC24A5 was found to have a particular mutation that is directly related to fair skin. The A111T mutation is most frequently seen in Ireland, and those who have it have a shared genetic code that comes from just one person.

Furthermore, given Ireland’s relatively distant northern position, it is likely that northern white Europeans have invaded and settled the island most frequently, further concentrating these genes. In northern regions, having fair skin is helpful because there is insufficient sunshine to produce Vitamin D, which is necessary for healthy bone growth and illness prevention.

11. The Healthiest Skin Color

The Healthiest Skin Color

Researchers from the UK’s universities of St. Andrews and Bristol discovered that a person’s skin tone has an impact on how healthy and consequently attractive they appear. People who had more blood and oxygen in their skin color appeared to be in good health.

The study’s findings that rosier skin appeared healthier were supported by the fact that skin that was somewhat flushed with blood and full of oxygen signals a powerful heart and lungs.

Furthermore, the research suggests that maintaining the best complexion may require a healthy diet. The “carotenoid pigments” that we obtain from the fruit and vegetables in our diet may be the reason why people view skin with a more golden or “yellow-toned” tone as healthier. These plant pigments act as potent antioxidants by soaking up harmful substances created as the body fights sickness.

12. Dermatophagoides Eat Dead Skin Cells

Dermatophagoides Eat Dead Skin Cells

The dermatophagoides or dust mite is a common household pest that feeds on dust particles that land on surfaces, including the skin. On beds, pillows, and any surface with keratin strewn about, they can grow and feed on keratin. These dust mites cause allergies in certain people.

Dermatophagoides Eat Dead Skin Cells

As opposed to some other mites, dust mites do not consume human blood. It is a fallacy that dust mites dwell on people, though they may “hitchhike” on clothing. They eat mostly the dead skin flakes that are shed by people and animals, called dander.

13. Melanin Contributes To Your Skin Color

Melanin Contributes To Your Skin Color

Melanocytes located in the skin create melanin. The pigment melanin comes in two varieties. Eumelanin, a brownish-black pigment, and pheomelanin, a reddish-yellow pigment with high sulfur content. Lightly and darkly pigmented people have different skin tones depending on how active their melanocytes are, not how many melanocytes are present in their skin. 

Melanin Contributes To Your Skin Color

More melanin is generated, is found in dense concentrations, and degrades more slowly in those with darker skin. Melanin is found clumped close to the keratinocyte nucleus in those with lighter skin, giving the cells a paler hue. Additionally, it deteriorates significantly faster in light-skinned persons.

When exposed to the sun, damaging UV rays from the sun start to damage the DNA in the skin cells as they pass through the skin. The body tries to make more melanin to protect the cells in reaction to this cellular harm. The characteristic “tan” on the skin is produced by an increase in melanin synthesis.

14. UV Radiation Can Damage Your Skin

Melanin Contributes To Your Skin Color

Sunburn can be caused by excessive UV exposure. The deeper layers of the skin are exposed to the UV radiation, which can harm or kill skin cells there. People should take precautions, especially if they are light-skinned and prone to sunburn. Covering exposed skin, using sunscreen, minimizing total exposure time, and staying out of the sun from 10 am to 2 pm are all ways to protect yourself.

Melanin Contributes To Your Skin Color

Infertility, congenital abnormalities, and skin cancer can all be made more likely by excessive UV radiation exposure. It can also increase the production of folate, which prevents healthy cell division. Rickets and other bone abnormalities can result from insufficient UV exposure because of the decreased generation of vitamin D.

15. The World’s Stretchiest Skin

UV Radiation Can Damage Your Skin

Garry Turner has a unique medical ailment called Ehlers-Danlos Syndrome, which allowed him to stretch the skin of his stomach to a swollen length of 15.8 cm. It is a connective tissue disorder that affects the skin, ligaments, and internal organs. He marked his record as the World’s Stretchiest Skin on 29 October 1999 in the UK.

In fact, the collagen that supports the skin and regulates its suppleness may take damage from this disorder. As a result, it contributes to “hypermobility” of the joints as well as a loosening of the skin. In more severe circumstances, it may result in the deadly rupture or collapse of blood vessels.
