Introduction: The Pimple Predicament

The episode kicks off with the Trusty Narrator sharing a relatable and humorous predicament: waking up with a giant pimple on his forehead just before speaking at the fictional "SmartyCon" conference. This anecdote sets a light-hearted tone for the episode and introduces the central theme of skin care.

[00:31] Trusty Narrator: "Just go with it... Oh, no. What's that on my face? Is that a giant zit on my forehead?"

Understanding Pimples: Causes and Commonality

The Narrator engages the young audience with a multiple-choice question about what a zit is, reinforcing learning through interactive trivia.

[00:43] Trusty Narrator: "Is it A, a type of dessert, B, a clogged or infected oil gland, or C, a type of hair? Did you say B? Great job, smarty pants."

He explains that pimples, or zits, are "small pustules or papules," caused by clogged and infected sebaceous glands. The discussion highlights that pimples are a common skin issue affecting everyone from time to time.

[01:01] Trusty Narrator: "Pimples develop when your oil glands... become clogged and infected, leading to swollen red lesions filled with pus."

The Importance of Skin: Largest Organ and Its Functions

Transitioning from the personal anecdote, the Narrator poses pivotal questions about the skin's role and importance, setting the stage for an educational deep dive.

[07:03] Trusty Narrator: "True or false, smarty pants? Your skin is your body's largest organ."

Dr. Debbie, the dermatologist guest, clarifies that skin is indeed the largest organ and introduces the concept of the integumentary system, which includes skin, hair, nails, sweat, and oil glands.

[07:35] Dr. Debbie: "Your skin and all its derivatives... make up what's known as your integumentary system, which is your body's outer layer."

Layers of the Skin: Epidermis, Dermis, and Hypodermis

A significant portion of the episode is dedicated to exploring the three layers of the skin:

1. Epidermis (Outer Layer):

   • Function: Protects against bacteria, germs, and environmental elements like rain and sun.
   • Cell Renewal: Generates new skin cells to replace roughly 40,000 shed daily.

   [08:13] Dr. Debbie: "The epidermis... keeps bacteria and germs from entering your body and bloodstream... It also continually makes new skin cells."

2. Dermis (Middle Layer):

   • Components: Contains collagen and elastin for strength and flexibility.
   • Additional Roles: Grows hair, contains nerve receptors, produces oil and sweat, and supplies blood to the epidermis.

   [10:08] Dr. Debbie: "The dermis... has collagen and elastin in it... grows hair and contains nerve receptors which help you feel pain and differentiate between temperature."

3. Hypodermis (Bottom Layer):

   • Function: Acts as a cushion to protect muscles and bones, contains connective tissue, and regulates body temperature through fat storage.

   [10:43] Dr. Debbie: "The hypodermis... contains fat, which acts as a cushion protecting your muscles and bones from injuries... It also helps regulate your body's temperature."

Skin's Protective Role and Health Maintenance

Dr. Debbie emphasizes the skin's role in the immune system and its protective functions. She explains how the skin acts as the first line of defense against various threats, including sun damage, allergies, and infections.

[09:38] Trusty Narrator: "Smarty pants, see if you can guess something that is determined by your epidermis... the amount of melanin... determines the color of your skin as well as your hair and eyes."

Skin Care Tips: The PALMS Acronym

Towards the end of the episode, Dr. Debbie introduces the PALMS acronym as a mnemonic device to help kids remember essential skin care practices:

1. P – Pat Dry: Gently patting the skin dry instead of rubbing vigorously.

   [16:41] Dr. Debbie: "P stands for pat dry. Instead of rubbing your skin really hard with a towel after a bath or shower, try gently patting yourself dry instead."

2. A – Avoid Harsh Soaps: Steering clear of soaps with excessive chemicals.

   [16:41] Dr. Debbie: "A stands for avoiding harsh soaps with lots of chemicals."

3. L – Limit Bath Time: Keeping showers short and using lukewarm water to preserve skin oils.

   [16:41] Dr. Debbie: "L stands for limiting bath time as hot water and long showers can remove healthy oils from your skin."

4. M – Moisturize: Applying moisturizer to maintain skin hydration.

   [16:41] Dr. Debbie: "M stands for moisturizing dry skin."

5. S – Shave Carefully: Using lubricants like shaving creams or gels to protect the skin during shaving.

   [16:41] Dr. Debbie: "S stands for shave carefully. Always use lubricants like shaving creams or gels before shaving."

The Narrator humorously acknowledges that shaving might be more relevant to adults, reinforcing the episode's kid-friendly approach.

[17:55] Dr. Debbie: "Great. Just think of PALMS and you'll look and feel Skin Credible."

Conclusion: Embracing Healthy Skin Habits

The episode wraps up with a playful exchange between the Narrator and Dr. Debbie, reinforcing the importance of caring for one's skin and maintaining a positive self-image.

[18:00] Trusty Narrator: "Nice one."

[18:01] Dr. Debbie: "Thanks, trusty. Gimme some skin."

Transcript

[Debbie]

Psst.

[Trusty Narrator]

Hey there, smarty pants. I just woke up. Or should I say, I just rolled out of bed. I didn't sleep much last night because I was so excited and a little nervous for today. Why am I so excited? Nervous? Well, this afternoon I'm speaking about podcasts at smartycon. That's like Comic Con for who Smarted fans.

[Narrator]

Yeah, it doesn't really exist yet, but.

[Trusty Narrator]

Just go with it. Anywho, there's going to be lots of imaginary smarty pants at my imaginary Smarty Con, so I want to look my imaginary best. What do you do to prepare for a big day? Me? I start with a quick shower, brushing my teeth, and flossing. Okay, I think that's everything. Now it's time to get dressed and. Oh, no. What's that on my face? Is that a giant zit on my forehead? Smarty pants. Have you ever seen a zit before? If you know any teenagers, the answer is probably yes. But do you know exactly what a zit is? Is it A, a type of dessert, B, a clogged or infected oil gland, or C, a type of hair? Did you say B? Great job, smarty pants. You're right. A zit, otherwise known as a pimple, is a small pustule or papule, which means blister or raised skin. Pimples develop when your oil glands, also known as sebaceous glands, become clogged and infected, leading to swollen red lesions form filled with pus.

[Audience Member]

Gross.

[Trusty Narrator]

While pimples are kind of gross, they're also very, very common. And pretty much everyone gets one or two or more from time to time. Some researchers believe stress can cause pimples, which makes sense why I'd get one this morning. I've been very excited, nervous, and stressed about Smarty Con. But here's the thing. Pimples are just one of many things that can happen to your skin. And pimples can show up anywhere on your body where you have skin. Right now I bet you're thinking, hey, wait a minute. Don't I have skin everywhere on my body? Yep, you sure do. And so does everyone, you know. But what exactly is skin? Why is skin so important? And what are the best ways to take care of your skin? It's time for another whiff of science. On who Smarted.

[Trusty Narrator]

Okay, smarty pants, since I've got this big pimple on my forehead, I decided to visit a dermatology office. Do you know what dermatology is, smarty pants? Is it A, a branch of medicine dealing with teenagers, B, a branch of medicine dealing with oily potato chip, or C, a branch of medicine dealing with skin? You probably said C, and you'd be right. Ah, here I am. The dermatologist's office. Luckily, my dermatologist is one of the best. She is an expert at epidermis, a savant of skin care, a connoisseur of complexion, the top popper of pimples, the.

[Debbie]

Okay, okay, trusty. I think you're getting a little carried away, but I do appreciate such a lovely introduction. Hi, smarty pants. You can call me Debbie.

[Trusty Narrator]

Yes, Dr. Debbie the dermatologist is truly a genius of cutis, which is the true skin or dermis.

[Debbie]

That's right. And the word dermis comes from the word epidermis, which comes from the Greek word derma. All meaning skin. Skin. Which is why a dermatologist is a doctor that deals with skin.

[Trusty Narrator]

Now, some of you may be wondering why I need such a great dermatologist when you never actually see me. But the truth is, it's really important that you take care of your skin.

[Debbie]

I couldn't agree more. Trusty. Or should I say pimply?

[Trusty Narrator]

Ah, I See? You've noticed the enormous zit on my forehead.

[Debbie]

It's not small.

[Trusty Narrator]

Oh boy.

[Debbie]

But I've seen a lot worse. And don't worry, pimples are very natural and happen to everyone.

[Trusty Narrator]

That's what I said, smarty pants. You should never ever feel bad if or when you get a pimple. Of course, when you're speaking at a smarty con, real or imagined, it's better to not have a giant pimple for everyone to focus on instead of listening to what you're saying. Dr. Debbie, can you help me?

[Debbie]

Not only can I help you, I can answer any questions about skin.

[Narrator]

Great.

[Trusty Narrator]

You know, I always have questions.

[Narrator]

Let's start with a basic one.

[Trusty Narrator]

What exactly is skin?

[Debbie]

Simply put, your skin is an organ.

[Trusty Narrator]

An organ? Like this?

[Debbie]

No, not that type of organ. More like your heart or your lungs.

[Trusty Narrator]

Oh, that's interesting. True or false, smarty pants? Your skin is your body's largest organ. Well, unless you have a heart that's bigger than you, the answer is true. If you got that right, smarty pants, go ahead and give the skin on.

[Narrator]

Your back a well deserved pat.

[Trusty Narrator]

Of course, it seems a little strange to think of your skin as an organ. Most of your organs, like heart, lungs, liver, skin, spleen and pancreas are inside of your body.

[Debbie]

But your skin is what's known as an external organ because it's outside your body. In fact, your skin and all its derivatives, hair, nails, sweat and oil glands make up what's known as your integumentary system, which is your body's outer layer.

[Trusty Narrator]

Wow, that's cool. What else can you tell us about our skin?

[Debbie]

Human skin is divided into three layers of tissue. These three layers, epidermis, the top layer, dermis, the middle layer, and hypodermis, the bottom or fatty layer.

[Trusty Narrator]

Wow, who knew your skin had layers? It reminds me of cake. Which reminds me, I haven't eaten yet. It's too bad my skin isn't made out of cake.

[Debbie]

As fun as it might be to have cake skin, it wouldn't be very practical or safe.

[Trusty Narrator]

Probably not. So what makes your skin so important?

[Debbie]

Your skin is important for a multitude of reasons, and each layer has its specific functions. The epidermis, or outer layer, keeps bacteria and germs from entering your body and bloodstream and causing infections. It also protects against the rain, sun and other elements. The epidermis also continually makes new skin cells. These new cells replace the approximately 40,000 old skin cells your body sheds every day. In fact, you have new skin every 30 days.

[Trusty Narrator]

Whoa, wait. I'M not wearing the same skin I wore last month.

[Debbie]

Nope. You're like a whole new you.

[Trusty Narrator]

Well, it still fits like my skin.

[Debbie]

Of course, it's important you be comfortable in your own skin.

[Trusty Narrator]

You better leave the trusty narrator jokes to the trusty narrator.

[Debbie]

Yeah, I'll stick to skin anyway. The reason you shed your skin is because it gets damaged. Everything from the sun, allergies, rashes and disease and more are constantly attacking your skin. Your epidermis is part of your body's immune system and the first line of defense in fighting off germs and and infections. But that's not all the epidermis does.

[Trusty Narrator]

Smarty pants, see if you can guess something that is determined by your epidermis, specifically the melanin that is contained within your epidermis. Here's a Melanin is a pigment and pigment determines color. So the amount of melanin in your epidermis determines the color of your skin as well as your hair and eyes.

[Debbie]

People who produce more melanin have darker skin and may tan more quickly.

[Trusty Narrator]

Wow. The epidermis sure does a lot. What about the other layers?

[Debbie]

The dermis, or middle layer, has collagen and elastin in it, which are proteins that keep your skin strong and flexible. The dermis also grows hair and contains nerve receptors which help you feel pain and differentiate between temperature of items. The dermis also makes oil, produces sweat, and supplies blood to your epidermis through vessels that keep your epidermis healthy.

[Trusty Narrator]

Wow, sounds like the dermis is also pretty busy. Surely the hypodermis doesn't have to do too much, right?

[Debbie]

Wrong. The hypodermis, or bottom layer of skin is equally as important as the top two layers. The hypodermis contains fat, which acts as a cushion protecting your muscles and bones from injuries like a bad fall. The hypodermis also has connective tissue which attaches your skin to your muscles and bones. Finally, the hypodermis helps regulate your body's temperature. The fat in the hypodermis keeps your body from getting too hot or too cold.

[Trusty Narrator]

Sounds to me like all three layers of skin are important.

[Debbie]

Yes, your skin is healthiest when all three layers are acting in perfect harmony like an awesome musical trio.

[Trusty Narrator]

Wow. Human skin is truly fascinating.

[Debbie]

Most people take their skin for granted, which is funny since it's your biggest organ, plays a huge role in your health and well being, and is a part of you. Most people see.

[Narrator]

Dr. Debbie, what are some ways we.

[Trusty Narrator]

Can take care of our skin?

[Debbie]

Great question, but I suggest we look at that pimple on your forehead first.

[Trusty Narrator]

Right? I almost forgot why I was here. We'll get back to some serious skin care and some prime pimple popping right.

[Trusty Narrator]

Now back to WhoSmarted Smarty Pants. I'm with Dr. Deborah, a dermatologist who has finished examining a megazit on my forehead. So what's your pimple prognosis, doc?

[Debbie]

There's nothing to worry about, trusty. I washed it up, put some ointment with acne medication in it to eliminate the pimple, and you should be good as new in no time.

[Trusty Narrator]

Great, so it'll be gone in time for Smarty Con?

[Debbie]

No, no, I'm afraid it doesn't work that fast. However, I have two ideas you can try.

[Narrator]

Yes, please.

[Trusty Narrator]

What are they?

[Debbie]

Maybe open with a joke. Like you could say, at first I didn't love this big pimple on my face, but it's growing on me.

[Trusty Narrator]

What's the second idea?

[Debbie]

Maybe some concealer cream?

[Trusty Narrator]

Oh, that sounds good. I'll pick some up at the drugstore. But wait, before I go, you were about to share with the smarty pants some ways that they can take care of their skin and keep it healthy.

[Debbie]

Yes, of course. I always advise to all my patients to look at their palms for their answer to healthy skin care.

[Trusty Narrator]

Like the palms of my hand?

[Debbie]

Not quite. Although it might help the palms of your hands. And it's spelled the same way. Palms. P A L, M S is an acronym.

[Trusty Narrator]

Oh, smarty pants. Do you know what an acronym is? An acronym is an abbreviation made from the first letters of other words to spell out a new word. For example, NASA is an acronym for National Aeronautics and Space Administration.

[Debbie]

Yep. And this is palms. P stands for pat dry. Instead of rubbing your skin really hard with a towel after a bath or shower, try gently patting yourself dry instead. The A stands for avoiding harsh soaps with lots of chemicals. The L stands for limiting bath time as hot water and long showers can remove healthy oils from your skin. I M stands for moisturizing dry skin and S stands for shave carefully. Always use lubricants like shaving creams or gels before shaving.

[Trusty Narrator]

Cool, cool, cool. Although I don't think the Smarty pants need to worry about shaving just yet, but the Smartie adults could take heed.

[Debbie]

Great. Just think of palms and you'll look and feel Skin Credible.

[Trusty Narrator]

Nice one.

[Debbie]

Thanks trusty. Gimme some skin.

[Trusty Narrator]

A super smarty shout out to Roland in Hollywood, Maryland.

[Narrator]

We hear you always say yes to.

[Trusty Narrator]

Who smarted, whether in the car or anytime. Now that's the enthusiasm for smarting that.

[Narrator]

We like to hear.
