Signs of over-moisturizing the skin // Can you MOISTURIZE TOO MUCH? @DrDrayzday
Summary
TLDRThis video explores the possibility of overdoing it with moisturizer and whether it can be detrimental. It explains the role of moisturizers in maintaining skin's natural barrier by reducing water loss and keeping irritants out. The script delves into the skin's stratum corneum, its composition, and the importance of water content for skin health. It addresses common misconceptions, such as causing oiliness or acne, and conditions like diaper rash and maskne, which are not caused by moisturizer overuse. The video concludes that while overuse is possible, it's unlikely with typical moisturizer application, and they are generally beneficial for skin health.
Takeaways
- 💧 Moisturizers are essential for maintaining skin health by reducing water loss and keeping irritants out.
- 🧱 The skin's outermost layer, the stratum corneum, functions as a barrier with 'bricks and mortar' made of corneocytes and lipids.
- 🌊 Natural Moisturizing Factors (NMFs) within the skin help bind water and maintain hydration.
- 🛡️ Environmental factors like detergents and pollutants can damage the skin's protective barrier, leading to dryness and irritation.
- 💦 Humectants in moisturizers mimic the skin's NMFs by attracting and binding water to the skin's surface.
- 🔒 Occlusives in moisturizers form a barrier on the skin's surface, trapping water in and preventing transepidermal water loss.
- 🚫 Over-moisturizing is unlikely with typical use, but conditions like diaper rash and 'maskne' can occur from excessive hydration.
- 🏊♂️ Swimmers may experience acne due to hyper-hydration from prolonged water exposure, not from moisturizer use.
- 👐 Frequent hand washing can disrupt the skin's lipid barrier, making regular hand moisturization important.
- ☀️ Sunscreen is considered a type of moisturizer as it contains humectants and is occlusive, helping to reduce water loss and protect from UV damage.
Q & A
Is it possible to overdo it with moisturizer?
-Yes, it is possible to overdo it with moisturizer, but it's not likely to cause issues like diaper rash or trench foot, which are due to prolonged contact with water, not moisturizer use.
What is the primary function of moisturizers?
-Moisturizers primarily help the skin by reducing water loss and helping to keep irritants out.
How does the skin naturally protect itself from water loss and irritants?
-The skin naturally protects itself through the stratum corneum, which is composed of dead cells called corneocytes enmeshed in a lipid protein matrix, acting like bricks and mortar.
What are the two strategies moisturizers employ to help the skin?
-Moisturizers employ two strategies: increasing water content in the stratum corneum with humectants like glycerin and hyaluronic acid, and depositing a water-insoluble oily substance on the skin surface to mimic the skin's lipids and trap water in.
Why is petrolatum a favorite occlusive in moisturizers?
-Petrolatum is a favorite occlusive in moisturizers because it can reduce water loss out of the skin by 99% and does a good job mimicking the skin's lipids.
Can moisturizers cause acne or oiliness?
-Moisturizers do not cause acne or oiliness. Oil production is governed by hormones and is not influenced by moisturizer application.
What is 'maskne' and how is it related to moisturizers?
-'Maskne' refers to acne caused by wearing masks, which can trap sweat and moisture against the skin. While moisturizers are not the direct cause, using an occlusive moisturizer can help prevent further irritation and promote skin healing.
How often should one apply moisturizer?
-The frequency of applying moisturizer depends on individual skin needs and conditions. Generally, after cleansing, and more often if hands are washed frequently or if one has dry skin conditions like eczema.
What is the role of sunscreen as a moisturizer?
-Sunscreen acts like a moisturizer by containing humectants and being occlusive, helping to reduce water loss from the skin and prevent dryness caused by UV exposure.
Can using too much moisturizer cause contact dermatitis?
-Using too much moisturizer can potentially cause contact dermatitis if one is allergic or sensitive to an ingredient in the moisturizer, but this is not due to the hydration itself.
What is the recommended approach to moisturizing for swimmers?
-For swimmers, it is recommended to use an occlusive moisturizer before entering the pool to prevent the skin from absorbing too much irritating pool water, and to rinse the skin after swimming to remove chlorine.

💧 Moisturizing: How It Works and Its Importance
This paragraph discusses the role of moisturizers in maintaining skin health. It explains that moisturizers help reduce water loss and protect the skin from irritants. The skin's outermost layer, the stratum corneum, is composed of dead cells and lipids that form a protective barrier. As we age or under certain conditions, this barrier can become compromised, leading to dry and irritated skin. Moisturizers combat this by increasing water content and depositing an oily substance on the skin's surface to mimic the skin's natural lipids and prevent water loss. The paragraph also dispels the myth that moisturizers are not suitable for oily skin, emphasizing that everyone can benefit from their use.
🚫 Debunking Over-Moisturizing Myths
The paragraph addresses the possibility of overdoing moisturizer application. It explains that while there is a point at which the stratum corneum can become overly hydrated, it is unlikely to occur from using moisturizers. Conditions like diaper rash and 'maskne' are cited as examples of over-hydration, but these are due to external factors like prolonged moisture exposure, not moisturizer use. The paragraph also discusses how occlusive moisturizers can actually help in these situations by reducing water loss and preventing further irritation. It concludes by mentioning that using too much moisturizer does not increase oil production, which is hormone-regulated, and that swimmers may experience acne due to water absorption rather than moisturizer use.
🛑 When to Use Moisturizer and Potential Side Effects
This paragraph provides guidance on when to apply moisturizer, suggesting that it should be used after cleansing and possibly more frequently for those with dry skin conditions or in winter. It also recommends reapplying moisturizer to the hands often, especially due to frequent handwashing. The paragraph touches on the benefits of using sunscreen, which acts like a moisturizer by reducing water loss and protecting against UV rays. It concludes by discussing potential adverse effects from using any skincare product, such as contact dermatitis from allergens or irritants, and notes that moisturizers can actually help to reduce irritation by keeping the skin hydrated.

well hey guys in this video i'm going to
be talking about over doing it with
moisturizer is that even possible can
you have too much of a good thing why do
we even moisturize in the first place
moisturizers help our skin in terms of
reducing water loss and helping our skin
to keep irritating things out but isn't
that the job of our skin in the first
place yes
how does it do that well skin the
outermost layer is called the stratum
corneum it's composed of essentially
dead cells called cornea sites that are
enmeshed in this lipid protein milieu
think of it as bricks and mortar there
are specialized proteins in between the
cornea sides called cornea desmosomes
that rivet between them and with time
those degrade and that allows for
shedding of the cornea sites and what's
called declamation or basically
exfoliation now when the water content
of the stratum corneum drops that can be
delayed and of course with age and in
certain dry skin conditions that can get
a little slow as well and that is what
leads to
dry heaped up skin cells and ultimately
that can impair the health of that
barrier function now also within that
you've got these lipids that help to
seal water in and keep irritating things
from getting getting into the skin and
causing problems for you within that
milieu you also have hydroscopic factors
that bind water there and hold it in
place that's referred to as natural
moisturizing factors
now it'd be all well and good if that
just was there on the top of the skin
doing its thing plugging and chugging
along during our day-to-day life though
we are exposed to a lot of things that
kind of eat away at that protective
layer detergent surfactants that we are
encounter with washing our hands
cleansing cosmetics makeup dirt
impurities pollutants all sorts of
things settle on the surface of the skin
that protective layer can become
impaired you can start losing more water
and water plays a critical role in the
function of the skin barrier it's
important for enzyme activity when our
moisture barrier is impaired then we
lose more water from the skin we're more
prone to irritation that can lead to
acne flares redness all sorts of skin
problems so herein is the role for
moisturizers and why they are helpful
moisturizers employ two strategies the
first is to increase the water content
in the stratum corneum through the
inclusion of hydroscopic
ingredients namely humectants things
like glycerin hyaluronic acid that bind
water there they kind of mimic your
skin's natural moisturizing factor and
the second strategy behind moisturizers
is to deposit a water insoluble oily
substance on the surface of the skin
that will kind of mimic the skin's
intracellular lipids to trap water in
there and prevent trans epidermal water
loss those ingredients are known as
occlusives and one of my favorites is
petrolatum why because it can reduce
water loss out of the skin
by 99
and it does a good job mimicking the
skin's lipids it can intercalate between
those cornea sites and moisturizers help
address the needs of the skin barrier
and everyone can benefit from that
including people who have oily skin it
is a myth that if you have oily skin
then you know moisturizers are somehow
beneath you can you have too much of a
good thing can you have too much
moisture in the skin the short answer is
yes but it's not likely because you are
using a moisturizer so there is a
tipping point where you can have too
much hydration in the stratum corneum it
can be hyper hydrated there are a few
conditions in which that occurs the
first situation that comes to mind is
diaper rash and diaper rash happens
because you have a moist environment in
the diaper with sweat
you know maybe urine or whatever getting
on the skin compromising the health of
the moisture barrier and it ends up
actually becoming hyper hydrated and the
end result of that is actually losing
even more water out of the skin so it's
kind of going too too far and impairing
the function of the moisture barrier and
that actually facilitates overgrowth of
certain types of bacteria and yeast and
can lead to
painful irritated rashes in the diaper
area but it's not just babies we have
another kind of similar
process that a lot of us experienced
over the past few years with the
pandemic and that is mask knee the same
sort of principle of over hydration of
the stratum corneum from trapping of
sweat moisture maybe saliva that gets
around your mouth as well
and that can end up causing a lot of
irritation
interestingly enough the remedy for both
of these situations is to use an
occlusive moisturizer to act as a
barrier to water loss out of the skin
and to prevent friction and further
irritation and compromise so that your
your skin can't heal and recover
same thing can also happen
in anywhere where you have skin on skin
contact under the armpits if you have
pendulous breasts or abdominal folds
especially in the heat of the summer you
get a lot of sweat that's trapped under
there hyper hydration of the stratum
corneum further irritation a moist humid
environment leads to overgrowth again of
yeast that causes a lot of inflammation
i mean there you have you have breakdown
of the skin barrier by virtue of
maceration and again the solution in
those situations is a topical barrier
cream so moisturizers remedy the
situation they don't cause it then you
have trench foot or immersion foot
syndrome
uh which is due to hyper hydration of
the stratum corneum of the feet this was
originally seen in world war one
soldiers
on the western front who had prolonged
exposure to wet muddy
immersion of their feet and what ends up
happening is the
stratum corneum of the bottom of your
feet is actually very very thick and it
can act as a sponge for water and absorb
200 percent as dry weight and water that
ends up leading to painful swelling of
the feet it can cause
nerve damage and it's actually you know
can be quite deadly and it's again a
hospitable environment for bacterial
overgrowth you can get deadly skin
infections so it was definitely a
problem
in soldiers and now they have better
shoes and whatnot better boots jungle
boots i think they're called
but it certainly still can happen we see
it a lot more now in like the homeless
population unfortunately but we're
talking days of exposure to water alone
it's not a situa it's not a condition
that is caused from using too much
moisturizer
now the treatment in that disease is to
rapidly dry the skin so there we
actually try and dry it out but again
this is not something that's going to
happen to you from using moisturizer now
i see a lot of musings on the interwebs
that using too much moisturizer can
actually end up making you oilier and
that is not true either oil production
is governed by your hormones and it's
not going to be influenced by putting
moisturizer on your skin now a group of
people however that can end up with
excessive oiliness and acne flares due
to hyper hydration of the stratum
corneum are actually swimmers but in
this case it's because they're in the
pool so much
and it has nothing to do with them using
too much moisturizer what ends up
happening is that and some in some
swimmers it's not everyone but the
stratum corneum ends up absorbing a lot
of water and it's thought that it kind
of acts like a sponge it swells and it
kind of blocks the pore
and
once that kind of remits a bit
then you have this outflow of sebum that
was prior previously kind of blocked up
from the swelling of the hyper hydrated
stratum corneum and those folks also can
develop acne flares now some of that
also has to do with the fact that
chlorine in the pool water is an
irritant to the follicle and can trigger
acne so it's a combination of things for
those individuals and again
interestingly enough the treatment here
or the prevention of this is to use
something occlusive
an occlusive moisturizer to the skin
before getting in the pool to prevent
that irritating pool water
your skin from soaking up too much of
that irritating pool water and then when
you get out oddly enough even though
it's a hyper hydrated stratum accordion
that you know we recommend swimmers
actually rinse their skin to remove that
chlorine water that is irritating so
there's a mechanism there for an acne
flare due to a hyper hydrated stratum
corneum in swimmers if you are a swimmer
i do have a video all about these little
skin manifestations that swimmers can
encounter so definitely check that out i
will link it down below in the d box
do you know what the d box is a side
note it's a description box there's like
a little arrow that you can expand it
and i put all sorts of stuff in there
that's where the time stamps are
and all sorts of goodies if i you know
reference a paper you'll find the
reference in there
so these skin conditions they come about
due to over hydration of the stratum
corneum but they're not due to using too
much moisturizer it's you know prolonged
contact with water
plus you know and or maceration i'm
hesitant to say that you can't overdo it
with moisturizer because i know there
you know will be inevitably someone out
there who goes overboard and is like
putting moisturizer on you know every
every minute
on the minute or something like that and
yeah that is excessive you certainly can
always overdo anything so i'm not
advocating for excessive use of
moisturizers i always encourage people
to use a moisturizer to the skin after
they have cleansed because the cleansing
action does disrupt some of the lipid
barrier and a moisturizer can help
reduce water loss out of the skin so if
you wash your face twice a day then
you'd be using a moisturizer twice a day
now if you have eczema or some other dry
skin condition or just a you know
tendency towards dryness maybe because
it's winter then you may find that you
benefit from putting on moisturizer
again at some other point in the day
when it comes to your hands i do
advocate
reapplying moisturizer to the hands a
bit more frequently because you are
going to be washing your hands a lot
especially if you you know
occupationally we're all washing our
hands a lot in that case you know that
constant stripping of the lipid barrier
it sets you up for dry hands and so
using a lot of occlusive moisturizer to
the hands is recommended and will
benefit those issues and then of course
sunscreen is basically a moisturizer
because it often will have humectants in
it and it is occlusive it helps reduce
water loss from the skin and if you're
going to be outdoors you need to be
reapplying sunscreen every two hours
ideally you know uv rays obviously they
put you at risk for skin cancer and
accelerated skin aging damage the
collagen in your skin and they aggravate
diseases of hyperpigmentation melasma
etc but they also make your skin drier
because they damage those proteins that
are part of that that outer shell and so
you do end up with more dryness
due to uv exposure and so you know
sunscreens not only are they protecting
you from the uv rays but they're also
kind of helping reduce water loss from
the skin and helping with just the
symptoms of dryness overall you know
you're not going to get trench foot
or
diaper rash from using moisturizers you
can develop adverse effects however to
using any skin care product probably one
of the most common adverse side effects
of using any skin care product is going
to be a contact dermatitis because on an
ingredient in the product you are either
allergic to or it's just your skin is
easily irritated by it most common
ingredients would be things like
fragrance
certain preservatives which really
aren't found too much in levon products
methyl isothiazolinone i don't find too
often in levon moisturizers although the
hota labo skin plumping gel cream that i
used to use does have that and i stopped
using that the other issue you can
encounter with moisturizing products is
that humectants they do increase the
penetration of other things
like for example hyaluronic acid
humectant it can help enhance
penetration of other things and when the
skin is well hydrated penetration of
things is greater so certain humectants
i can't increase the penetration of
other active ingredients and may make
them more irritating but actually using
a moisturizer ends up making it easier
to tolerate many irritating ingredients
just by helping to moisturize the skin
and reduce irritation i feel like i'm
going to get this question like well how
much is too much well how much is too
much
honestly there is not a definition if
you are putting moisturizer on every you
know minute two minutes three minutes
that's extreme
it's on an as needed basis so
you can overdo it if you're just
surreptitiously putting moisturizer on
that is not likely going to help you
it's just wasting the moisturizer all
right you guys i hope this helped answer
the question can you overdo it with
moisturizer water content is really
critical for the health and integrity of
the moisture barrier and the function of
the skin and moisturizers aim to
mimic your skin's natural moisturizing
factor ability for binding water and
then also those lipids for reducing
water loss and preventing irritating
things from getting into the skin so
moisturizers kind of step in and act
like second skin it's unlikely that you
can overdo it with them although you
know with the caveat that you certainly
can go overboard and unnecessarily
surreptitiously be applying moisturizer
but when used appropriately no you're
not going to be over doing it
anyways one last thing this shirt that
i'm wearing it's a new belief top i got
on the amazonian
i'm loving this color
it's got of course the hand sleeves and
it's just a little quarter zip
um i think it was like under 15
this brand believe i'm not sponsored by
them or anything
they i have like four or five
different upf 50 tops from them and they
hold up well
so highly recommend this it's very
comfortable very breathable
anyways
i hope you guys enjoyed this video if so
give it a thumbs up share with your
friends and as always don't forget
sunscreen and subscribe i'll talk to you
guys tomorrow bye
[Music]
you
