Welcome back!
Today, we are talking about
00:00:01.36\00:00:02.70
the skin - one of our
most important organs,
00:00:02.73\00:00:04.40
and, Dr. Marcum, we're about to
answer some questions on skin.
00:00:04.43\00:00:07.57
And our first question is:
"What does the skin actually do,
00:00:07.60\00:00:10.64
and what type of
doctor treats the skin?"
00:00:10.67\00:00:12.54
Yeah, well we touched
on that a little bit about
00:00:12.57\00:00:14.81
what the skin does and one
thing is that it's a barrier
00:00:14.84\00:00:18.61
and it sort of protects
us from our environment. Okay
00:00:18.65\00:00:22.15
You've probably heard the
term, "Do you have thick skin?"
00:00:22.18\00:00:25.55
Well thick skin helps
protect from the environment
00:00:25.59\00:00:28.92
and a lot of people
also realize that, you know,
00:00:28.96\00:00:31.73
hair growing out of skin,
that still counts as skin too...
00:00:31.76\00:00:34.23
So that hair growing out
of skin counts, the nails,
00:00:34.26\00:00:36.67
that sort of all
counts as skin too.
00:00:36.70\00:00:38.73
But one of the most
important functions of the skin
00:00:38.77\00:00:41.50
is to protect us
from the environment.
00:00:41.54\00:00:43.74
It can protect
us from infections.
00:00:43.77\00:00:46.91
And a lot of times
infections are spread
00:00:46.94\00:00:49.74
from person-to-person and we
want to keep the skin healthy
00:00:49.78\00:00:53.75
and intact.
00:00:53.78\00:00:55.12
We know that when skin is
cut or the barriers in skin
00:00:55.15\00:00:58.35
are broken, then all
of a sudden we have access
00:00:58.39\00:01:01.49
to the bloodstream.
00:01:01.52\00:01:02.86
So you can get an
infection in the bloodstream,
00:01:02.89\00:01:04.89
and it can spread very quickly.
00:01:04.93\00:01:07.00
So first and
foremost, the skin is a barrier
00:01:07.03\00:01:09.63
to help our protection.
00:01:09.66\00:01:11.30
The skin also
helps in heat regulation.
00:01:11.33\00:01:14.67
You know, keeps us
warm, keeps us cold.
00:01:14.70\00:01:16.67
Everyone knows when
you get out in the cold,
00:01:16.71\00:01:18.97
what does the skin do?
00:01:19.01\00:01:20.64
You shiver - you
shiver! That's right
00:01:20.68\00:01:22.04
Because you want to keep
the temperature in. Right
00:01:22.08\00:01:24.58
If you don't keep
the temperature in,
00:01:24.61\00:01:26.55
bad things happen.
00:01:26.58\00:01:28.18
When you stop shivering,
there's a problem. Right!
00:01:28.22\00:01:30.19
You don't want to
get too cold. Right
00:01:30.22\00:01:32.15
Too cold is not
good for the body.
00:01:32.19\00:01:34.26
I personally do
not like cold weather.
00:01:34.29\00:01:36.22
I will do
anything to keep warm. Sure
00:01:36.26\00:01:38.49
I put coats, sweaters, anything,
00:01:38.53\00:01:40.10
I'm just not a
cold-weather person, Nick.
00:01:40.13\00:01:42.13
Another thing that
the skin does is...
00:01:42.16\00:01:44.43
If you're out in the
heat - what does the skin do?
00:01:44.47\00:01:46.94
Then it lets out heat
to keep your cool down.
00:01:46.97\00:01:50.31
You know, you lose
fluid, it evaporates,
00:01:50.34\00:01:52.57
so it helps
regulate your temperature.
00:01:52.61\00:01:55.24
It helps protect you.
00:01:55.28\00:01:56.81
Those are some of the two most
00:01:56.85\00:01:59.45
important functions of the skin.
00:01:59.48\00:02:02.08
In fact, a lot of
people don't realize that an
00:02:02.12\00:02:04.19
average person can
sweat about 3 gallons a day.
00:02:04.22\00:02:09.32
Okay, 3 gallons
a day. Really? Wow!
00:02:09.36\00:02:10.76
Yeah, you look at your pets and
that's how they lose the fluid,
00:02:10.79\00:02:15.03
but that's quite a
bit... I mean 3 gallons a day,
00:02:15.06\00:02:17.97
that sounds like a lot - I'm
going to have to check on that.
00:02:18.00\00:02:20.34
But it might be -
I'll have to check,
00:02:20.37\00:02:22.10
but it might have
been 3 quarts a day.
00:02:22.14\00:02:23.47
But basically, we lose a lot
of fluid from our skin. Right
00:02:23.51\00:02:26.51
Remind me to check on that
one, that sounded like a lot.
00:02:26.54\00:02:28.81
I'll do that! I
don't know which.
00:02:28.84\00:02:30.35
Now the doctor,
that's important.
00:02:30.38\00:02:31.81
Now how do you know if
you have a skin problem
00:02:31.85\00:02:33.98
that needs a doctor? Yeah right
00:02:34.02\00:02:35.35
Well almost everyone
out there, at some point,
00:02:35.38\00:02:38.42
they've had a
funny rash on them.
00:02:38.45\00:02:40.66
And it behooves
everyone to understand
00:02:40.69\00:02:44.19
what's an important rash and
what's not an important rash.
00:02:44.23\00:02:47.53
The specialist in that
is called, "dermatologist,"
00:02:47.56\00:02:50.73
skin - derm - dermatologist,
a specialist in skin.
00:02:50.77\00:02:53.70
So all they do is they
are a specialist in looking at
00:02:53.74\00:02:56.71
all the different conditions and
rashes that come with the skin.
00:02:56.74\00:02:59.91
Then when you go to
them, they look at it,
00:02:59.94\00:03:01.91
and most of the time a
great dermatologist has seen
00:03:01.94\00:03:04.21
everything - they know what it
is and what to do immediately.
00:03:04.25\00:03:07.72
So if you ever have a skin
condition that won't go away,
00:03:07.75\00:03:11.15
that's a major
issue, then a dermatologist
00:03:11.19\00:03:14.09
is the person to go to.
00:03:14.12\00:03:16.12
You have conditions
like psoriasis and eczema
00:03:16.16\00:03:20.30
that we see - those
are type of skin conditions
00:03:20.33\00:03:22.50
that people go to.
00:03:22.53\00:03:23.87
Moles and things that
are turning colors, growing,
00:03:23.90\00:03:27.34
that's a place to
see a dermatologist.
00:03:27.37\00:03:29.87
There are some
types of infections
00:03:29.90\00:03:31.81
that get on the skin.
00:03:31.84\00:03:33.17
We've seen fungal
infections where you have itches
00:03:33.21\00:03:37.11
and you scratch it a lot
and it's not an exposure,
00:03:37.15\00:03:40.95
it's just a fungus
that's there. Right
00:03:40.98\00:03:43.25
And you would treat
that with an antifungal.
00:03:43.28\00:03:45.72
We talked about this
here... This is a steroid
00:03:45.75\00:03:48.89
cream and this would be good
for just a local inflammation.
00:03:48.92\00:03:52.19
But you wouldn't want to put
this on a fungus infection...
00:03:52.23\00:03:55.06
You would want
an antifungal. Okay
00:03:55.10\00:03:57.47
Yeah, something that would
get at the cause of the problem.
00:03:57.50\00:03:59.97
And the skin is like any other
organ that we've talked about,
00:04:00.00\00:04:03.54
or any organ system because
you want to get at the cause,
00:04:03.57\00:04:06.61
and use medicines to
sort of get you over the hump.
00:04:06.64\00:04:09.74
So the first thing in
these skin conditions is go to
00:04:09.78\00:04:13.21
somebody that can identify what
it is - if you don't know it.
00:04:13.25\00:04:16.12
Now there are sometimes
you can have a condition
00:04:16.15\00:04:18.32
that's very common
called, "contact dermatitis."
00:04:18.35\00:04:22.39
That's where you're in contact
with something that irritates
00:04:22.42\00:04:25.49
your skin and it
causes inflammation.
00:04:25.53\00:04:28.00
This steroid cream would be
very good for that inflammation
00:04:28.03\00:04:31.90
because of the inflammatory
response that comes by
00:04:31.93\00:04:35.14
what would do with clothes,
00:04:37.87\00:04:40.28
a different cleaner might do it.
00:04:40.31\00:04:42.88
Some people might have something
that blows on their skin
00:04:42.91\00:04:45.65
that could irritate it. Right
00:04:45.68\00:04:47.08
All sorts of
things can cause it.
00:04:47.12\00:04:48.45
You know, if you wear
clothes that are too tight
00:04:48.48\00:04:51.05
for long periods of time,
00:04:51.09\00:04:52.45
sometimes that
can cause irritation
00:04:52.49\00:04:54.02
and a rash and irritation. Yes
00:04:54.06\00:04:55.96
So lots of things, but
what I want to advise people,
00:04:55.99\00:04:57.86
if you have something
that will not go away,
00:04:57.89\00:05:00.60
it's there a long time,
something that's changing
00:05:00.63\00:05:03.53
that you need help with
right away or if you have a rash
00:05:03.57\00:05:07.07
and other symptoms - that's
the time to get help right away
00:05:07.10\00:05:10.64
because sometimes, like we
said, a rash could be a sign
00:05:10.67\00:05:13.01
of a condition like "lupus,"
could be a sign of an other
00:05:13.04\00:05:16.11
medical condition and,
of course, the most serious
00:05:16.14\00:05:18.65
thing we think of is... is
this a sign of a skin cancer?
00:05:18.68\00:05:22.45
Now we know that water is
very important to our skin. YES!
00:05:22.48\00:05:25.22
Both to drink water and
also to wash with water.
00:05:25.25\00:05:28.39
What makes our
skin smelly sometimes?
00:05:28.42\00:05:30.73
Yeah, well, the skin gets smelly
00:05:30.76\00:05:33.56
because of the
bacteria in the skin.
00:05:33.60\00:05:37.80
The skin constantly sort
of secretes this greasy stuff,
00:05:37.83\00:05:41.97
and bacteria love
warm, moist, dark places,
00:05:42.00\00:05:45.17
that's where they like to grow.
00:05:45.21\00:05:46.94
So if something is
warm, moist and dark
00:05:46.98\00:05:48.51
over long periods of
time whether it be under the
00:05:48.54\00:05:50.75
underarms or in creases
of skin, and especially if
00:05:50.78\00:05:54.25
it's moist - that's
when bacteria start to grow,
00:05:54.28\00:05:58.22
and that's why it's so
important to stay clean. Yeah
00:05:58.25\00:06:01.76
And remember, water
is good for the inside,
00:06:01.79\00:06:04.13
but it's also
good for the outside.
00:06:04.16\00:06:05.86
We want to keep
those parts of us clean,
00:06:05.89\00:06:07.66
and we also want to
keep those parts of us
00:06:07.70\00:06:10.87
you know, we want them
dry, because if it gets
00:06:10.90\00:06:14.04
moist over long periods
of time, that's a place where
00:06:14.07\00:06:16.74
bacteria, fungus and things
like that can sort of grow
00:06:16.77\00:06:19.37
and take over.
00:06:19.41\00:06:21.14
So warm, moist -
not good for the skin.
00:06:21.18\00:06:23.81
Dry - really good for the skin.
00:06:23.85\00:06:26.25
And we also know that sunlight
is an important thing for us,
00:06:26.28\00:06:29.35
but what about sunscreen?
00:06:29.38\00:06:30.79
Who should wear
sunscreen and how long should
00:06:30.82\00:06:33.19
we worry about sun exposure?
00:06:33.22\00:06:34.56
Well this is very interesting,
Nick, is that for many years
00:06:34.59\00:06:39.19
in the history of the
earth, people have been exposed
00:06:39.23\00:06:42.46
to the sun, and 500 years
ago, they didn't have sunscreen.
00:06:42.50\00:06:48.94
Did those people do
poorly? I don't know.
00:06:48.97\00:06:51.51
But what the dangerous
thing is about the skin is when
00:06:51.54\00:06:54.11
it's prolonged
exposure to the rays.
00:06:54.14\00:06:57.95
And what it does
is, it damages the skin,
00:06:57.98\00:07:00.08
and then people get sunburn.
00:07:00.12\00:07:01.58
So sunburn is not good and
now for those that like to lie
00:07:01.62\00:07:05.52
in tanning beds, we
found out that tanning beds
00:07:05.55\00:07:08.89
isn't so good for the skin.
00:07:08.92\00:07:10.69
But it is good for the skin
to get out and get some sun,
00:07:10.73\00:07:13.43
and get some color as
long as you don't burn.
00:07:13.46\00:07:16.23
And, we've recommended
that at least you would be out
00:07:16.26\00:07:19.00
in the sun at least
30 minutes 3 times a day,
00:07:19.03\00:07:21.37
but we don't want to burn.
00:07:21.40\00:07:22.80
And people that
have long sun exposure,
00:07:22.84\00:07:25.71
that's not healthy either,
so let's say you're a lifeguard,
00:07:25.74\00:07:29.61
now you used to go
out and ski a lot, right?
00:07:29.64\00:07:31.51
Yeah, I used to
teach kids in summer camp
00:07:31.55\00:07:32.95
how to water ski.
Now I have a question...
00:07:33.01\00:07:34.35
Your skin was exposed for pretty
long periods of time. Yeah
00:07:34.38\00:07:38.82
Unfortunately probably too long.
00:07:38.85\00:07:40.46
Did you brown or burn?
00:07:40.49\00:07:42.02
The first part of the season,
I might burn once or twice,
00:07:42.06\00:07:45.49
but then I'd brown
pretty well after that.
00:07:45.53\00:07:46.96
So, you might be one,
if you're going to be out
00:07:47.00\00:07:49.23
for long periods of time,
you want to protect your skin,
00:07:49.26\00:07:52.53
not so much for the acute event,
but for 20 years down the road..
00:07:52.57\00:07:56.87
Because you damage
your skin when you're young,
00:07:56.91\00:07:58.81
then when you're older
a couple of things happen.
00:07:58.84\00:08:00.84
One is that you're at
a higher risk of cancer.
00:08:00.88\00:08:03.01
Two, premature aging.
00:08:03.04\00:08:05.51
You know, too much burning
of the skin causes wrinkles
00:08:05.55\00:08:08.15
and damages the
skin in that way.
00:08:08.18\00:08:10.02
So a person like that
would benefit from being on
00:08:10.05\00:08:12.85
a sunscreen - you know,
one of the SP sunscreens,
00:08:12.89\00:08:15.59
and they have different
strengths that block the sun.
00:08:15.62\00:08:18.29
And so a person like that...
For instance, I know marathon
00:08:18.33\00:08:22.26
runners that are fair-skinned...
00:08:22.30\00:08:24.47
They're going to be
out running all day.
00:08:24.50\00:08:26.57
Well those are people that
might benefit from being on
00:08:26.60\00:08:29.20
a sunscreen to help
block the sun, so when they're
00:08:29.24\00:08:32.11
not running 6 or 8
hours into the race,
00:08:32.14\00:08:34.58
then they get a sun burn
and they have lots of pain
00:08:34.61\00:08:38.08
to go with everything else.
00:08:38.11\00:08:39.51
But I find if people
will take care of their skin,
00:08:39.55\00:08:42.32
and be smart about how
they get out and just gradually
00:08:42.35\00:08:45.52
build up, then the
pigment will be able to accept
00:08:45.55\00:08:48.12
that without burning.
00:08:48.16\00:08:49.79
Now tell me, how can I tell
if a discoloration on my skin
00:08:49.82\00:08:54.20
is cancer?
00:08:54.23\00:08:55.80
Well, sometimes it's hard
to tell exactly if it's cancer,
00:08:55.83\00:08:59.60
but there's a couple of
characteristics of skin cancer
00:08:59.63\00:09:02.70
that people should be aware of.
00:09:02.74\00:09:05.24
So if you look a mole...
00:09:05.27\00:09:07.68
A fancy name for
mole is called a "nevi,"
00:09:07.71\00:09:10.08
and I'm looking to see if I have
a mole here on my skin that's..
00:09:10.11\00:09:14.92
I've got some normal moles,
but if you look at a mole,
00:09:14.95\00:09:17.85
and it's starting to
change colors, it's turning blue
00:09:17.89\00:09:21.42
or it's getting
hair growing out of it,
00:09:21.46\00:09:24.39
that's one sign that's not good.
00:09:24.43\00:09:26.26
It becomes crusty - it starts
bleeding - that's not good!
00:09:26.29\00:09:31.43
If it has a change in
the contour, that's not good.
00:09:31.47\00:09:35.74
Or anytime you just
have something that comes up
00:09:35.77\00:09:38.57
that used to not be there
and it's changing quickly,
00:09:38.61\00:09:41.84
and it is growing quickly.
00:09:41.88\00:09:43.21
Well that's one that, if I
were you, I would go to the
00:09:43.24\00:09:46.05
dermatologist and when
you go to the dermatologist,
00:09:46.08\00:09:49.38
he'll look at it and say, "Oh,
that could be a skin cancer,
00:09:49.42\00:09:51.95
let's do a biopsy and there's
a simple procedure where they do
00:09:51.99\00:09:55.52
what they call a "punch
biopsy," where they take it out,
00:09:55.56\00:09:57.99
they look at it
under the microscope.
00:09:58.03\00:10:00.00
If it is a skin cancer,
they can determine what it is
00:10:00.03\00:10:03.77
and make sure the
margins and all cancer is gone.
00:10:03.80\00:10:06.50
They can do it right there that
is called a "Mohs" procedure.
00:10:06.53\00:10:09.60
So very skilled doctors can
continue making sure the cancer
00:10:09.64\00:10:12.91
is resected.
00:10:12.94\00:10:14.34
They can tell
you if it is cancer.
00:10:14.38\00:10:16.21
They can also say, "Well this
is just "seborrheic dermatitis"
00:10:16.24\00:10:19.28
or something that's not serious.
00:10:19.31\00:10:20.65
Or this is just a routine nevi
00:10:20.68\00:10:23.12
that doesn't need
to be worried about.
00:10:23.18\00:10:24.99
So a dermatologist
is the best to do that,
00:10:25.02\00:10:26.79
and sometimes people have moles
00:10:26.82\00:10:28.32
that are irritating on
their skin that causes bleeding
00:10:28.36\00:10:31.03
and we see that in people
that have clothes that are
00:10:31.06\00:10:34.03
in bad positions and
it keeps rubbing on a mole
00:10:34.06\00:10:37.10
or nevi and they
could take that away with
00:10:37.13\00:10:39.97
numerous ways even with cold.
00:10:40.00\00:10:42.57
They can get a
cold-pack type thing,
00:10:42.60\00:10:44.31
they can get those moles
gone so it doesn't bother you.
00:10:44.34\00:10:47.08
So getting back
to your question...
00:10:47.11\00:10:48.54
If it's changing
colors, if it's growing,
00:10:48.58\00:10:50.18
if it's bleeding, if
it looks ugly or just
00:10:50.21\00:10:52.31
doesn't look right
to you, get some help.
00:10:52.35\00:10:54.75
Now that's another good point...
00:10:54.78\00:10:56.12
You cannot see all your
skin surface, can you, Nick?
00:10:56.15\00:10:58.45
No, I sure can't.
00:10:58.49\00:10:59.82
I can't see behind
me, I don't have...
00:10:59.85\00:11:01.36
So you should
occasionally have someone
00:11:01.39\00:11:03.69
look at your entire skin.
00:11:03.73\00:11:06.16
And that includes
the scalp which is not
00:11:06.19\00:11:08.56
looked at very much,
the skin behind the ears,
00:11:08.60\00:11:11.53
the skin in the back,
the skin all over your body,
00:11:11.57\00:11:13.77
just to make sure you don't
have a suspicious mole growing.
00:11:13.80\00:11:18.51
It's recommended that at
certain ages that we have a
00:11:18.54\00:11:21.84
complete skin exam by a doctor.
00:11:21.88\00:11:24.05
And I don't know, most people
have never had their entire
00:11:24.08\00:11:27.38
skin surface looked at,
but I think that it's a very
00:11:27.42\00:11:31.49
good thing to do occasionally
00:11:31.52\00:11:32.85
so you can keep track of it...
00:11:32.89\00:11:35.62
I've known a few
people that have melanoma.
00:11:35.66\00:11:37.63
That's the most serious
skin cancer that exists,
00:11:37.66\00:11:40.36
and if a melanoma has spread
and is not detected early,
00:11:40.40\00:11:44.33
that is very fatal and a very
dangerous form of skin cancer.
00:11:44.37\00:11:48.30
So I want to advise
everyone that's watching there
00:11:48.34\00:11:50.57
if you have a funny
spot, have a dermatologist
00:11:50.61\00:11:53.21
or your doctor
take a look at it.
00:11:53.24\00:11:54.74
Have your spouse, friend, loved
one or someone that you like
00:11:54.78\00:11:57.48
a lot look at the
back part of your body,
00:11:57.51\00:11:59.75
the parts of your
body that you can't see,
00:11:59.78\00:12:01.55
to make sure that you don't
have a suspicious mole growing
00:12:01.58\00:12:03.89
that might be a
cancer. That's a good idea.
00:12:03.92\00:12:05.95
And you mentioned the scalp
earlier and we have another
00:12:06.09\00:12:08.46
question that has come
in from a viewer that asks:
00:12:08.49\00:12:10.29
"Is balding caused by bad skin?"
00:12:10.33\00:12:13.19
Balding caused by bad skin.
00:12:13.23\00:12:14.96
Well, I looked into that
a little bit because I was
00:12:15.00\00:12:18.13
going to get one
of those balding...
00:12:18.17\00:12:19.97
You know, I'm losing a few,
in my hair and I was wondering
00:12:20.00\00:12:23.54
if I should get one of
those special creams to do,
00:12:23.57\00:12:26.47
you know,
wanted to do that. Sure
00:12:26.51\00:12:27.84
Well, it's not due to
bad skin, but it's due to
00:12:27.88\00:12:31.11
mainly it's a
genetic thing for most of us.
00:12:31.15\00:12:34.02
Now there are certain medical
conditions that cause balding,
00:12:34.05\00:12:36.89
you know, thyroid disease
and certain things like that,
00:12:36.92\00:12:40.12
but most males with
male pattern balding
00:12:40.16\00:12:42.82
is a genetic
thing and unfortunately
00:12:42.86\00:12:46.13
there's a lot of hair
care products out there
00:12:46.16\00:12:48.30
for alopecia and most
of them don't help a lot.
00:12:48.33\00:12:51.80
But what does seem to
help is to get more blood flow
00:12:51.83\00:12:55.67
to the skin. Right
00:12:55.70\00:12:57.64
That seems to help
the skin out quite a bit.
00:12:57.67\00:12:59.94
So in the
products that seem to help,
00:12:59.97\00:13:01.64
if you're losing hair,
one thing that might help
00:13:01.68\00:13:04.38
is to rub the part of
the body that's losing hair
00:13:04.41\00:13:07.65
and it can grow - it can
get more blood supply to it...
00:13:07.68\00:13:11.62
That might help
retard it if it's genetics.
00:13:11.65\00:13:14.32
You know what I don't
understand, Nick, is I'm losing
00:13:14.36\00:13:16.69
more hair on my
head, but I'm growing
00:13:16.73\00:13:19.49
more hair in other parts
of my body including my ears!
00:13:19.53\00:13:23.30
You know, that's
crazy - my ears and my nose,
00:13:23.33\00:13:25.57
plenty of hair there
but up here it's going away!
00:13:25.60\00:13:28.30
But it's not really a
systemic skin condition,
00:13:28.34\00:13:30.87
it's more of a
genetic condition.
00:13:30.91\00:13:32.44
We've got
another viewer who asks:
00:13:32.47\00:13:34.08
"My skin is dry,
what should I do?"
00:13:34.11\00:13:36.21
How do you work with dry skin?
00:13:36.24\00:13:37.71
Dry skin, let me drink
a glass of water here...
00:13:37.75\00:13:41.35
That's one of the most
common skin problems we have
00:13:41.38\00:13:44.89
is dry skin.
00:13:44.92\00:13:46.25
When the skin gets
dry, the problem is
00:13:46.29\00:13:48.39
that people start
itching it and they rub it,
00:13:48.42\00:13:51.63
and before long, it gets
inflamed and it gets sort of
00:13:51.66\00:13:54.30
like what we call, "dermatitis,"
and then all of a sudden
00:13:54.33\00:13:58.33
sometimes people rub it
so much that the skin breaks.
00:13:58.37\00:14:01.87
And then when the skin
breaks, because there's bacteria
00:14:01.90\00:14:04.41
on the skin, you're
subject to infections.
00:14:04.44\00:14:06.81
So dry skin is a
fairly serious problem.
00:14:06.84\00:14:09.51
The first thing that I think
the most important thing for
00:14:09.54\00:14:12.01
dry skin is: (a)
Drink more water.
00:14:12.05\00:14:14.92
Make sure you're very,
very, very well-hydrated.
00:14:14.95\00:14:19.02
That's very important.
00:14:19.05\00:14:20.82
Some people that
take hot showers sometimes
00:14:20.86\00:14:23.66
can have problems with dry skin.
00:14:23.69\00:14:25.23
And there are certain
parts of the body that are more
00:14:25.26\00:14:27.90
prone to dry skin.
00:14:27.93\00:14:29.50
Down where the socks
are, that area, tends to be
00:14:29.53\00:14:32.67
more prone to dry skin and
in parts of the skin that are
00:14:32.70\00:14:35.50
very dry, in
addition to drinking water,
00:14:35.54\00:14:38.07
there are also some very
good products that are out there
00:14:38.11\00:14:41.54
that help moisturize
the skin and that can help
00:14:41.58\00:14:44.81
moisturize the skin.
00:14:44.85\00:14:46.18
I use one called
"Eucerin Cream," but there are
00:14:46.21\00:14:51.15
also other different
types of moisturizers
00:14:51.19\00:14:54.96
that work as well and your
pharmacist or dermatologist
00:14:54.99\00:14:58.96
will lead you in that direction.
00:14:58.99\00:15:00.70
Dry skin, especially
in the cold in the winter,
00:15:00.73\00:15:04.10
it's very important as
people have more dry skin.
00:15:04.13\00:15:07.54
And the real danger is if you
don't get that taken care of,
00:15:07.57\00:15:10.94
it can lead to
other problems. Right
00:15:10.97\00:15:12.97
I don't like dry skin. Right!
00:15:13.01\00:15:14.64
We've got another
question: "What about acne?"
00:15:14.68\00:15:16.95
"I'm a very self-conscious,
18-year-old, I need help."
00:15:16.98\00:15:20.75
What do we do about acne?
00:15:20.78\00:15:22.12
Well acne is a very big problem
and it's bacteria on the skin,
00:15:22.15\00:15:26.05
lots of hormones and
things going on in kids.
00:15:26.09\00:15:28.82
We see it flare up a
lot, but, you know, I was
00:15:28.86\00:15:31.66
reading a recent study - I do
a lot of work with nutritionists
00:15:31.69\00:15:36.13
and Dr. Greger is one of
the nutritionists I work with,
00:15:36.16\00:15:39.20
he's a doctor that
studies that and he found
00:15:39.23\00:15:41.04
out that if guys and
gals and that would just go
00:15:41.07\00:15:45.71
to a whole food, plant-based
diet and get all that
00:15:45.74\00:15:49.78
garbage food out of them,
that's something that really
00:15:51.08\00:15:53.92
helps in the
development of acne.
00:15:53.95\00:15:56.45
Now if it goes beyond
that, of course, there are
00:15:56.48\00:15:59.02
creams that can be used.
00:15:59.05\00:16:00.39
In severe cases, they
give some antibiotics,
00:16:00.42\00:16:02.86
but I want to tell those
that are fighting with acne
00:16:02.89\00:16:04.73
right now - try going to a
whole food, plant-based diet,
00:16:05.16\00:16:10.23
and see if that won't really
help turn the acne around.
00:16:10.27\00:16:13.57
Everyone that I've seen that's
gone on a strict diet like that
00:16:13.60\00:16:16.20
has had dramatic
improvements in their skin.
00:16:16.24\00:16:19.44
In fact, everyone that
wants to have healthier skin,
00:16:19.47\00:16:22.64
that's something they can do.
00:16:22.68\00:16:24.65
One of the things that
that type of diet does is it
00:16:24.68\00:16:27.05
removes fat and protein
and all these other junk
00:16:27.08\00:16:30.59
that our skin gets
- it can remove that,
00:16:30.62\00:16:33.22
and the other thing it does
is it helps our blood vessels
00:16:33.25\00:16:35.89
of our skin become healthier and
get a healthier blood supply.
00:16:35.92\00:16:39.46
So people that eat a healthy
diet, lots of whole foods,
00:16:39.49\00:16:42.76
lots of real foods,
gets a better blood supply;
00:16:42.80\00:16:45.57
they look more
alive; they're more dynamic;
00:16:45.60\00:16:47.90
they have a better blood supply;
00:16:47.94\00:16:49.37
their skin just works
better and functions better.
00:16:49.40\00:16:51.84
It's something that's
underestimated in the care of
00:16:51.87\00:16:55.34
the skin is our
nutrition, so I want everyone to
00:16:55.38\00:16:58.21
eat that whole
food, plant-based diet.
00:16:58.25\00:17:00.18
We'll do that and we'll
drink some water and try
00:17:00.22\00:17:02.28
and stay out of
the sun. We'll do that.
00:17:02.32\00:17:05.09
We hope this has been
beneficial for you at home.
00:17:05.12\00:17:07.36
Stay tuned, Dr.
Marcum is going to lead us

skin today and I want to just
