Did you know these amazing things about your skin? Let's talk!

Hello! How are you? Today we are going to talk about one of the most amazing and largest organs in our body. Yes, yes, that is our skin, or the epidermis . Sometimes we don't think much about this skin, but our skin is actually a superhero that works amazingly, protects us, and controls many things in our body. Just think, how would we live without this skin? So, today we will talk about this friend called our skin in a little more detail.

Our skin, hair, nails, oil glands , and sweat glands all come together to form the integumentary system. Simply put, this is the outer covering of our body.

How is our skin made? What are the main layers?

Okay, now let's look at the main parts, or layers, of our skin. To be precise, our skin is made up of three main layers. It's like an onion with a peel, that's what it is. These three layers are:

• The top layer: This is called the epidermis . This is the part of the skin that we see and touch.
• The middle layer: This is the dermis .
• The fatty layer underneath: This is called the hypodermis .

Now let's look at what happens in each of these layers separately.

What happens to the top layer - the epidermis?

You see, the part of your skin that you touch is called the `(Epidermis)`. This is very special. It mainly contains cells made of a protein called `(Keratin)` . These cells and other proteins come together to form this top layer, the `(Epidermis). Let's see what the main things are that come out of this?

• Acts as a protective shield: Imagine, this is what protects our body from germs and bacteria. It also helps protect us from things in the environment like dust, water, sun, and wind. Just think, without this protection, how easily diseases would develop, right? It's like an armor placed on our body.
• Makes new skin: Did you know that our `(Epidermis)` is constantly making new skin cells . Every day, about 40,000 skin cells die and are shed from our bodies. These new cells are produced to replace those dead cells. That means that on average, in about 30 days, you have brand new skin! Isn't this amazing?
• Protects the body (helps with immunity): This `(Epidermis)` contains a special type of cell called `Langerhans cells` . They are part of our body's immune system. They help a lot in fighting germs and preventing infections.
• Gives skin color: The pigment called `` Melanin`` gives our skin, hair, and eyes their color. The amount of ``Melanin`` determines your skin color. People who produce more ``Melanin`` have darker skin, they burn less easily in the sun, and they also tan more easily, which means they turn a little brown.

What happens to the middle layer - the dermis?

90% of the thickness of our skin is in this middle layer called ``Dermis''. This also performs many very important functions.

• There are collagen and elastin: Collagen is a protein that strengthens our skin cells and gives them elasticity. Another protein called elastin is what gives the skin its elasticity, that is, its stretchiness. Like a rubber band. It is this elastin that helps the skin to go back to its original shape when it is stretched.
• Hair grows: Not only the hair on our heads, but also the hair follicles on our bodies are located in this `(Dermis)`.
• Touch makes you feel: Imagine if you accidentally touched a hot cup of tea, would you say, 'Oh, urine !'? Or when you scratch something, when you touch something very smooth, that feeling is provided by the nerves in the `(Dermis)`. Pain is felt because of these nerve receptors.
• Oil production: Oil glands in the dermis produce an oil that helps keep our skin smooth and soft. This oil is what keeps water from getting into our skin when we shower or get wet in the rain.
• Sweating: Sweat is produced by sweat glands in the dermis and comes out through the pores of the skin. Sweating helps control our body temperature .
• Blood supply: The blood vessels in the dermis supply the upper layer, the epidermis, with the nutrients it needs. This keeps the skin layers healthy.

What happens to the bottom layer - the hypodermis?

This is the fat-filled layer underneath our skin. This also has many benefits for us.

• Like a cushion for muscles and bones: Like a pillow, the fat in this ``Hypodermis'' reduces the damage to the muscles and bones inside us when we fall or have an accident.
• There is connective tissue: This tissue is what connects the layers of skin to muscles and bones.
• Nerves andHelps blood vessels : The nerves and blood vessels in the middle layer, the `(Dermis), become larger as they reach the `(Hypodermis). These are the ones that connect the `(Hypodermis)` to the rest of the body.
• Regulates body temperature: The fat in the `(Hypodermis)` prevents us from feeling too cold or too hot. It's like `insulation` on our bodies.

What else does our skin contain?

Just think, just one inch of your skin contains about 19 million skin cells! In addition, there are about 60,000 melanocytes , which give skin its color, about 1,000 nerve endings , and about 20 blood vessels. Isn't it amazing that so much can be packed into such a small area?

What diseases and conditions affect the skin?

As the outermost layer of our body, the skin is more susceptible to various problems and diseases. Some of them are:

• Allergies: Contact dermatitis, which occurs when you touch certain things or certain plants (such as poison ivy).
• Blisters: Small blisters filled with fluid.
• Insect bites: These are caused by bites from animals such as mosquitoes, ants, spiders, and ticks.
• Skin cancer: Dangerous types of skin cancer such as melanoma .
• Skin infections: Bacterial infections like cellulitis . These bacteria can develop when there is a wound.
• Skin rashes and dry skin: These are common things that many people experience.
• Specific skin diseases: Acne , Eczema , Psoriasis , and Vitiligo , which are skin discolorations.
• Skin spots: Things like birthmarks, freckles, and skin warts.
• Wounds, burns (including sunburns) and scars.

Things like this show how sensitive our skin is and how much it is exposed to.

How can I protect my skin?

As we age, the amount of `(Collagen)` and `(Elastin)` in our skin decreases. This causes the middle layer of the skin, the `(Dermis),` to become thinner. As a result, the skin starts to sag and wrinkle.

While we can't stop aging, there are things we can do to keep our skin healthy. A little effort can make a big difference.

Here are some things you can do:

• Apply sunscreen every time you go out in the sun. It's a good idea to apply sunscreen even if you're indoors for a long time, or even when you're out for a short time. Use at least SPF (Sun Protection Factor) 30.Choose a broad-spectrum sunscreen (which protects against all types of sun rays).
• Don't tan. Tanning, whether indoors in tanning beds or outdoors in the sun, damages your skin. It can age your skin faster and even lead to skin cancer.
• Find good ways to manage stress. Some skin conditions can be exacerbated by stress.
• Check your skin and moles regularly for changes that could be signs of skin cancer.
• If you smoke, stop. Nicotine and other chemicals in cigarettes and electronic cigarettes can cause skin to age faster.
• Use a gentle cleanser to wash your face morning and night. Harsh soaps can dry out your skin.
• Wash your body regularly and apply a moisturizing lotion before your skin dries. This can help prevent your skin from drying out.

These things may seem a little difficult, but once you get used to them, they're really easy. Your skin will thank you!

What time should I see a doctor?

Although you can usually treat minor conditions at home, sometimes it's necessary to seek medical advice. If you experience any of the following, be sure to see a doctor:

• If the color, shape, size, or symmetry of a birthmark on your body changes.
• If something like a new birthmark appears on the skin.
• If you have a cut that cannot be covered with a plaster at home and may need stitches.
• If you have a severe burn that causes blisters.
• If you see signs of a skin infection: for example, if a wound is oozing yellow pus, or if there are red streaks.
• If you develop a rash for no reason, or if you develop another skin condition.

If you see things like this, it's best to see a doctor and get advice without delay.

Finally, what to remember (Take-Home Message)

The skin, the largest organ in our body, plays a very important role in protecting our body from germs and external influences. It also helps to maintain a comfortable body temperature and allows us to feel touch through the nerves under the skin. This outer covering can cause serious problems like skin cancer, as well as common problems like acne and skin blemishes. You can get advice from your doctor that can help you keep your skin healthy. So, take care of your skin, because it protects you every day!
