Q & A
日焼けサロンはなぜ肌に有害なのですか?
-日焼けサロンは主にUVA線を放射しており、これにより皮膚が急速に老化し、皮膚癌のリスクも高まります。UVA線は皮膚のDNAを損傷させ、老化を引き起こすことが知られています。
ニキビを破裂させるのはなぜ避けるべきですか?
-ニキビを破裂させると、毛穴ユニットを損傷し、周辺のコラーゲンに炎症を引き起こすため、傷跡が残りやすくなります。
アクネを予防するためにはどのような対策を取れば良いですか?
-アクネを予防するためには、アクネを引き起こす要因に対処するため、皮膚細胞の粘りや油分泌を減少させる成分を含むスポットトリートメントを使用することが有効です。
ヘアロスに対抗する完全な治療法はなぜ存在しないのですか?
-細胞はプログラムされた死のサイクルを経て、一定回数しか増殖できないため、ヘアロスに対する完全な治療法は存在しないと言われています。現在ある治療法は、ヘアロスの進行を遅延させ、一部の毛を再生するものです。
アクチノイン(Isotretinoin)はアクネ治療においてどのように作用しますか?
-アクチノインはアクネの原因となる4つの要素のうち、油分泌の増加、皮膚細胞の粘り、炎症を減少させる効果があり、アクネの治療において非常に効果的です。
ストレスが肌に与える影響とは何ですか?
-ストレスは生理学的にホルモンを放出し、このホルモンは皮膚の油腺に作用してアクネを引き起こすことがあります。また、ストレスは脱毛にも影響を与える可能性があります。
抗汗剤と除臭剤の違いは何ですか?
-抗汗剤は汗の分泌を阻止するのに対し、除臭剤は汗液の匂いを抑える効果しか持たないことが多く、安全性の点では除臭剤の方が優れていると言われています。
日焼けの危険性はどの程度ですか?
-日焼けはDNAに損傷を与え、皮膚癌の発生リスクを高めます。また、一度の重度の日焼けで皮膚癌のリスクが増加する可能性があります。
肌荒れはなぜ起こることがあるのですか?
-肌荒れは肌の水分を失ったり、肌の障壁が弱っていると起こることがあります。肌の水分を保ち、適切な保湿ケアを行うことで肌荒れを防ぐことができます。
刺青を削除する方法は何ですか?
-刺青を削除するためには、特定の色素を攻撃するレーザーを使用して、色素を小さな粒子に分解し、体の免疫システムが排除できるようにします。
アルコールフラッシュ(Asian Flush)はなぜ起こることがあるのですか?
-アルコールフラッシュは、アルコール代謝に関与する酵素の遺伝子変異により、アルコールを分解できない人で起こることがあります。この状態は、アルコールの毒性が原因で赤みや炎症を引き起こします。
皮膚が老化するにつれてしわが生じる理由は何ですか?
-皮膚が老化するにつれてしわが生じるのは、皮膚のボリュームが減少し、重力の影響で下に向かって移動し始めたこと、そして表情筋の動きによる皮膚のくすみが原因です。
肌の色が変化するメラノーマの特徴は何ですか?
-メラノーマの特徴は、非対称性、境界線の不規則性、色の多様性、直径の大きさ(6mm以上)、変化していることです。これらの症状がある場合は、すぐに皮膚科医院就诊する必要があります。
唇が日焼けをする可能性はありますか?
-はい、唇は他の皮膚と比べて保護層が薄いため、日焼けをすることがありえます。特にビーチなどで日焼けが起こりやすい場合は、 SPFを含むリップクリームを使用することが重要です。
マスクを長時間着用することで肌にどのような影響を与える可能性がありますか?
-マスクを長時間着用することで、肌にアクネや刺激を引き起こす可能性があります。肌への摩擦や密閉空間での湿度の上昇が原因で、肌の炎症を悪化させる可能性があります。
足のひじむきが乾燥して皺が入った場合は、皮膚科医に相談すべきですか?
-足のひじむきの乾燥やひびが入った場合は、足病医(ポジトリスト)または皮膚科医に相談することができます。両者ともに足の乾燥やひびを治療することができますが、足病医は足に関する専門知識を持っています。

🚫 タンニングの危険性とニキビの処理
Dr. Man Shaは、タニングが皮膚癌の原因になるだけでなく、急速に老化を促進すると警告。ニキビについては、自然に消えるのを待つか、効果的なスポットトリートメントを使用することが推奨され、ニキビを破裂させることで皮膚の傷痕や炎症後色素沈着を避けるべきだと述べています。また、毛の損失については、細胞のプログラムされた死滅と関連があり、完全な治愈はまだ見つかっていないが、治療はある程度の毛の成長を促進できる可能性があると説明しています。
🧪 アクチュアネの効果と副作用
アクチュアネ(イスオトレチノイン)は、ニキビの原因となる4つの要因のうち3つを効果的に減少させる薬剤であり、特に重度のノドゥロシスティックなニキビや皮膚の傷痕に対しては消滅的な効果があるとされています。しかし、副作用があり、すべての人に適しているわけではなく、適切な患者を選ぶ必要があるとDr. Man Shaは指摘しています。
😓 ストレスが皮膚への影響
ストレスが生理学的にニキビを引き起こすことが文書化されており、ストレスホルモンが皮膚の毛穴にある脂腺に作用し、ニキビを引き起こすことが説明されています。このサイクルは、ストレスがニキビを悪化させ、さらにストレスを増やす可能性があることを意味しています。髪の毛の損失にも同じメカニズムが考えられています。
🌞 日焼けと皮膚の老化
日焼けはDNAへの損傷を引き起こし、皮膚癌のリスクを高めることから危険であると警告されています。特に子供の頃の1回の重度の日焼けで皮膚癌のリスクが50%増加する可能性があることが強調されています。日焼けによる皮膚の老化は、UVBおよびUVA放射線による影響で、UVAが老化に寄与すると説明されています。
💧 肌の水分と保湿
肌は水分を失うことがあり、保湿は皮膚の健康を維持する上で非常に重要です。肌の水分を維持するための主な方法として、日光からの保護やレチノールなどのトピカルクリームを使用することが推奨されています。また、日焼けによる皮膚の損傷は、肌の水分を失う要因の1つであり、日焼けを防ぐことで肌の水分を維持することができます。
🤔 肌に関する一般的な疑問
様々な肌に関する疑問に対する答えが提供されています。例えば、耳の後ろの皮膚が裂ける理由、肌に水分を与える方法、肌の毒素を排除する方法、そして肌が呼吸するかどうかなど、様々なトピックに触れています。肌のケアに関するアドバイスとして、適切な保湿剤の使用や、肌に適した製品を選ぶことが重要であることが強調されています。
💉 皮膚の症状と治療
皮膚の症状に対する治療方法が説明されています。例えば、ニキビ、皮膚の赤斑、肌荒れ、肌の乾燥、そして皮膚の症状に対する一般的なアドバイスが提供されています。特に、肌のケアの基本として、適切な保湿と皮膚の障壁を保護することが重要であることが強調されています。
👩⚕️ 皮膚科の専門知識

the worst thing you can do for your skin
is go tanning not only do they cause
skin cancer but they also accelerate
aging rapidly hi I'm Dr man sha and this
is skin
[Music]
support So at Young forehead great
username should you or shouldn't you pop
your pimples I'm trying to settle a
debate all right let's settle this
debate right now anyone who follows me
knows I am very much against popping
your pimples they can lead to infections
they can lead to jarring we have to
think about what causes a pimple or
where is the pimple in your skin in
general it's actually stuck inside your
hair follicle unit or basically inside
your pore so this pimple is a little pus
Ball filled and stuck inside this pore
now it's restrained there which is fine
it's not going to cause any scarring at
this point the second that you pop it
you actually rupture that hair follicle
and it damages the surrounding collagen
because of all that inflammation so
that's where you get scarring so
definitely don't pop your pimples if you
don't want scarring if you don't want
that post-inflammatory hyperpig M mation
that sticks around forever there are so
many good spot treatments out nowadays
that eliminate your pimples pretty
quickly without you having to pop them
Mumbo Inc asked why is there no cure for
hair loss I wish there was because
everybody including myself suffers from
hair loss we don't have an answer yet
hopefully one day in my lifetime we will
have an answer but all of our cells go
through basically a programmed death
cycle they can only live so long they're
all meant to replicate a certain amount
of times and then eventually die off off
and our hair cells are exactly the same
way and once they die off you really
can't get them back and so we have
treatments in dermatology that can
actually stop the hair loss process slow
the hair loss process maybe get you a
few hairs back but nothing that's a
complete cure at this time hopefully one
day we do but if we ever to have a cell
that were to continue to replicate
forever and ever and never die off
that's exactly what cancer cells do so
we don't necessarily want that we need
to find something in between that lasts
long enough that we can produce hair
shafts forever but not last long enough
that it turns into a cancer rocking it
for you asked how safe are tanning
booths I used to go tanning all the time
as a result of that I ended up develing
being skin cancer at the age of 31 when
nobody in my family has ever had skin
cancer and I went tanning probably over
100 times so we know the tanning boosts
are going to increase your risk of skin
cancer we know that it's going to
accelerate aging as a matter of fact you
have UVB radiation and you have UVA
radiation now UVB radiation UVB b stands
for bad that's the one that damages your
DNA and mostly causes skin cancer and
then UVA mostly causes aging well our
tanning boosts are actually mostly UVA
so not only do they cause skin cancer
but they also accelerate aging rapidly
so that's why people that use tanning
beds often look much older than their
age and so they're not safe they
increase the risk of skin cancer and if
there's one thing that I do on all my
social media platforms and when I get on
here and I talk to all of you is the
worst thing you can do for your skin is
go tanning hjo PD asked hey Siri how do
I get rid of genital warts probably not
tweeting to everybody about your genital
warts would be a good start uh genital
warts are actually caused by the HPV or
human papiloma virus and that human
papiloma virus can cause cervical cancer
in women and it can also cause penile
cancer in men if you do have genital
warts that's something you want to get
treated and it's also something that you
don't want to spread to other people
especially your partner who could end up
with cervical or penile or anal cancer
as a result of that but once you have it
we do have several ways to get rid of it
including freezing them with liquid
nitrogen and using other topical
treatments like aamod which is a
prescription medication and others they
can get rid of them but I would have
them treated and not try to spread them
to other people but you have different
types of HPV vaccines that are very
effective at stopping you from getting
this in the first place now the HPV
vaccine is approved up to 45 but it
probably has even benefit beyond that
there's actually a new study that showed
that up to 87% % reduction in cervical
cancer in women so it actually makes a
huge difference if you get it and I
actually recommend it highly to people
especially at a young age to prevent
getting HPV in the first place next up
Dr ched asked how the heck does Accutane
work goodness gracious so Accutane is
actually no longer on the market but I
actually use that word still myself um
it's actually known as isotretinoin so
isotron and is a vitamin a derivative
but to understand how it works we have
to go back to what causes acne in the
first place so there's a few things that
cause acne one your skin cells basically
stick together too much and basically
clog your pores two you have bacteria
that's stuck in those pores clogging
those pores three you have increased oil
production that's trapped inside your
pores and four all of that bundle
creates inflammation so basically four
main things that causes acne Accutane or
isotretinoin targets three out of those
four very very effectively it decreases
oil production decreases skin cell
stickiness and decreases infl
and is the number one best treatment for
acne the problem is that it does have
some side effects that we do need to
monitor so it's not for everyone it's
not the answer for everyone's acne but
for people with really bad nodulocystic
or scarring acne it is an absolute
obliterating medication and
life-changing medication for people that
have acne next up we have GG rimon why
does my skin break out when I have
stress as if that won't stress me out
more ah this is such a good question so
when you have stress physiologically it
actually causes you to break out this is
actually something that's really well
documented we have a hormone released
from our hypothalamus called
corticotropin releasing hormone and it
actually acts on the sebaceous or sweat
or oil glands within the hair follicles
that actually causes acne so that stress
hormone acts on your hair follicle to
create the oil that causes acne that's
like the worst thing ever right cuz you
get stressed you break out you're
stressed out more because now you have
acne and it's just a vicious cycle and
you can actually get in your own head
and make your acne worse this is
actually true for hair loss too that
stress can cause hair loss or teagen
aium and you can end up in this vicious
cycle where your stress is actually
making your hair loss worse I could just
tell you like don't be stressed but I'm
stressed myself so I don't really have a
good answer for you uh but you know some
meditation in the morning you know
exercising can really get your mind off
things and just stick with a regimen
that works for acne and then that will
help to improve it but I can't eliminate
all stress in life I wish I could mini
poly me asked while we're talking about
stuff like this is anti-perspirant more
dangerous than deodorant so good
question and a lot of people just
consider these two to be the same thing
but they're actually very different so
anti-perspirants actually block echine
sweat from happening so they basically
include those Ducks the other side you
have deodorant which actually doesn't do
that it just is basically perfume
essentially for your armpits deodorants
in general are going to be considered to
be safer because there is some risk that
people speak of regarding aluminum if
you talk to most dermatologists and most
people in the scientific space they'll
tell you that that risk is unfounded so
there is some concern that aluminum can
cause cancer right now that's unfounded
so we definitely need more data now if
you're someone who's concerned about
this I think it's reasonable to just use
deodorant now personally from my
personal opinion it's not something that
I'm worried about I always make my
recommendations based on what I would
recommend to my mom my sister my dad my
wife based on my recommendations to my
own family members I'm not currently
worried about antiperspirants or
aluminum based deodorants that may
change as more data comes out but if you
are somebody who's concerned I think it
would be reasonable to use deodorant
that doesn't have the aluminum in it so
Sunshine R Kayla asked okay I have a
question skincare friends I've been
having issues pretty consistently with
breaking out on my cheeks just the lower
part I haven't changed anything in my
skincare routine but it's frustrating so
this is a really good and common
question hormonal acne can affect any
part of the face but specifically we
find that in women specifically in their
20s and 30s outside of those teenage
years seem to develop acne along the
jawline we don't necessarily know why
this happens some people think it has to
do with different receptors in the skin
at these levels but we do know that
people get hormonal acne specifically in
this region the treatment over the-
counter is going to be identical so
you're going to look for those acne
fighting ingredients salicylic acid
benzil peroxide adapalene or retinoids
that's all you can do for it over the
counter it's when you see a
dermatologist that we're going to treat
your hormonal acne different than we
would treat other forms of acne so what
we would essentially do is go after the
hormones instead of going after other
things that we usually treat acne with
we instead go after the actual hormones
and we give medications that regulate or
normalize your hormone production to get
you back into balance so room Aesthetics
asked why does skin wrinkle with age you
have to think about volume so you have
to picture yourself essentially as a
great so when you're young you're a
great when you get older you start to
lose volume your volume starts to head
in the direction of gravity and you
develop wrinkles or you become
essentially a raisin and the number two
thing is movement now you have to
picture yourself as a leather shoe when
you get a brand new leather shoe it's
got no creases in it but as soon as you
start to move and walk it develops
essentially a crease in it and that's
what happens when we move the muscles in
our face you develop wrinkles because of
that so it's volume and movement and
basically all the treatments that we
have in dermatology Aesthetics plastic
surgery actually Target one of these two
things to eliminate wrinkles you got to
ask yourself hey is this anti-aging
cream actually going to work for me it
has to Target one of these things it
either has to stop movement which we
don't really have any topical treatments
that can really do that effectively
there is a topical treatment called
argilene that may have some benefit
similar to Botox to stop movement but
beyond that we're thinking about how do
we restore volume so the first thing you
can do is protect your volume so one
thing is to actually wear sunscreen we
know that about 90% of the Aging that
happens to our skin is actually due to
the Sun and so by inhibiting the sun
effect on the skin by using sunscreen
that's going to do most of the work the
other thing is you could try to build
the volume that you lost by building the
collagen and support structures in your
skin the number one thing for that as
far as topical creams is going to be
your retinols or vitamin A derivatives
smart Solarium UK asked how dangerous is
sunburn can one case of severe sunburn
give you cancer so sadly yes in a way
because the way that skin cancers are
formed is basically a mutation in your
DNA must occur and that DNA mutation
leads to Rapid replication of one cell
so you really only have to get one bad
cell for this all to happen and so a
really bad sunburn could damage your DNA
to the point where you get an abnormal
cell that does turn into a skin cancer
now that is relatively uncommon but we
do know that just a single sunburn
during childhood could increase your
risk of skin cancer by 50% anytime you
get more sunburns it's going to be even
worse for you so not just melanoma but
you can also get squa cell skin cancers
basil cell skin cancers you can't
reverse what you did in the past so you
can't go back in time and stop your
sunburns but what you can do going
forward is wear sunscreen every day and
really try to get shade when you're out
in the sun at the beach coffeeology
asked what is the optimal SPF that I
should use on my face right now I have
SPF 15 but I'm not sure if it's
protective enough perfect segue here so
this is a common misconception because
the FDA actually recommends SPF 15 SPF
15 blocks about 93% of UVB radiation we
find that that's really not enough in
dermatology because people don't really
apply it thick enough as they're
supposed to from the American Academy of
Dermatology we really recommend SPF 30
or higher you don't need SPF 100 but SPF
30 to SPF 60 is really going to get you
there SPF 15 is probably not enough when
you get to SPF 30 you get 97% coverage
if you use thick enough of a layer
jungle go asked SOS help I got a
piercing around a month ago and I've
developed an infection in the area what
do I do crying face so this is July 15th
so I'm hoping they're okay it's been a
while hopefully they saw somebody um any
type of infection if it's starting to
spread or become painful or draining pus
definitely see a doctor for this
probably don't tweet unless the people
tweeting back at you were saying to go
see a doctor one of the things that you
can do is just clean the area with soap
and water clean Thea with alcohol
chlorexidine or iodine any wound those
are the best things to really clean it
with so you can use a topical antibiotic
ointment polysporin is a good option
especially in the United States clean
the area with soap and water if it
really starts to get worse and you start
to have fevers chills headaches or start
to feel really ill that's when you want
to see a doctor kc2 sjm asked Fact or
Crap windburn can be more dangerous and
last longer than a sunburn is this a
fact or is it crap specifically when we
talk about windburn or sunburn this is
actually a great debate in the
Dermatology Community there are some
dermatologists that don't even think
windburn exists they actually think that
windburn is actually just sunburn
disguised as being in the cold windy
times my opinion it's a combination of
both when it's windy and cold outside
the humidity is down wind is blowing in
your face your skin starts to crack and
get dry and it weakens Your Skin Barrier
and this makes you more sensitive to the
sun because now that top layer of your
skin can't protect you from the Sun so
it's a combination wind low humidity
plus the Sun that actually causes wind
bur the sunburn is actually more
dangerous because it's damaging your DNA
and the windburn May last longer because
it just takes you longer for your skin
to heal so it's a combination of the two
actually Gat sw8 asked does your skin
breathe and does it need to detox some
people will say hey my Skin's breaking
out I need to give it a chance to
breathe what the people are experiencing
in that situation is that a lot of times
their skincare products or make up is
actually making their skin worse they're
using products that are clogging their
pores or they're using products that are
actually irritating their skin and by
giving their skin a chance to quote
unquote breathe their skin may get
better as a result of that so no your
skin doesn't physiologically breathe but
giving your skin a breather from harsh
products that are damaging Your Skin
Barrier may actually be beneficial for
some people and we need to sweat because
it eliminates heat from our body it uh
regulates our electrolyte Productions in
our body but we don't necessarily need
to remove toxins from our skin our
kidneys and our liver do most of the job
doing that our skin does very little job
to detox our bodies R Welsh makeup asked
skincare question does anyone know why
some moisturizers make my face feel
sweaty a few seconds after applying it
like not just a moisture layer but like
I've been sweating when you're applying
a moisturizer you're basically applying
like a blanket to your face and that
increased heat or Suffocation of the
skin could essentially cause you to
sweat a little bit more moisturizers
actually prevent water water loss that's
the main mechanism by which they work so
if you start sweating and you apply a
moisturizer it's going to trap that
moisture that's coming out of your pores
right into the skin and so you may
actually be locking in your sweat and
just feeling a little bit more than you
probably normally would next up we have
Ted Talk ideas and if they're supposed
to last forever how does tattoo removal
work what ends up happening with tattoo
is that you're putting an ink underneath
the skin essentially into the durmis
layer of the skin and it basically sits
there and that's what we see when we
look at underneath the microscope we see
these little particles of black or red
dots sitting in that dermis layer of the
skin we used to think that tattoos would
last forever but then they inv invented
laser tattoo removal how does it work is
basically there's a specific laser beam
that targets what we call a chromophor
now a chromophor is anything that
absorbs light at a specific wavelength
if you have black tattoo ink the laser
will Target that specific black tattoo
ink and really nothing else and that's
the chromophor that it's attacking and
by hitting that with high power energy
laser beam essentially explodes these
into tiny little particles that your
body's able to finally absorb and get
rid of Amelia Chan asked why does my
sister have asian flush but I don't
you're luckier than your sister I
suppose but it certainly is genetic to
some degree so what ends up happening
with asian flush or alcohol flush they
drink alcohol and immediately they turn
beet red and it's actually kind of
painful for them it's very very
uncomfortable so alcohol needs to be be
converted and metabolized to basically
the inactive forms of it but what ends
up happening is people with asian flush
they have a mutation in their acetyl
alahh dehydrogenase Gene and that
mutation makes it so that they can't
break down acety alahh so alcohol is you
drink the alcohol it's converted to
acetyl alahh and then they're not able
to break it down that acetyl alahh built
up in the body causes tons of
inflammation flushing redness pain
throbbing sensation and actually people
with the mut in this particular enzyme
or gene or increased risk of esophageal
cancer when they drink because this
acetyl alahh is actually really toxic to
cells it's actually physiologically a
dangerous thing to have asian flush and
drink on at the same time so it doesn't
exclusively affect the Asian populations
it happens to be more common in the
Asian populations because it's passed
through essentially mitochondrial DNA
which is passed actually from the mom
usually uh you inherit your
mitochondrial DNA from and so it is
genetic it can happen in all populations
it just happens to be more common in the
Asian population next up jonovan asked
curious how you can spot skin cancer
what does it look like and are there any
symptoms like I was saying earlier skin
cancer can kind of look like anything
but the main thing that I would really
want to warn everybody about is
something called melanoma which is
basically when a mole becomes abnormal
and that's one of those dark or brown
looking moles we actually do have a
really helpful pneumonic for this and we
call that the ABCDE e of melanoma a
stands for asymmetry so if you were to
take a mole and you were to lay it over
on top of itself it was if it was
asymmetric that would be one sign that
it's not good b means basically the
borders are Jagged or abnormal c means
that it has more than one color so it's
not just one homogeneous same color
brown but there's specks of black
there's specks of brown there's specks
of Pinks that's abnormal you don't want
that either d stands for diameter
anything over 6 mm or the size of like a
pencil head a eraser head that's
concerning as well and the last thing is
e or evolving so any mole that's
changing growing bleeding all of a
sudden doesn't look the same as it did
before that's something to look for and
the last thing has actually become
recently recognized in the literature
what we call the Ugly Duckling sign so
basically it's when you have one mole
that just doesn't look like the rest of
the moles on your body if you have any
of those signs or symptoms you want to
see a dermatologist immediately the
depth of how deep that mole goes can be
life-changing if it goes too deep it
could have already spread if it's very
shallow then we may be able to just
remove it right in the office so not
something to wait on everything else you
can wait on if you have a pimple what
have you but if you have an abnormal or
changing mle that's not something you
want to wait on Libby asked can your
lips get sunburn something about lip
gloss at the beach seems dangerous you
certainly can get sunburn on your lips
as a matter of fact your risk of sunburn
on your lips is actually higher than the
rest of your skin because it doesn't
have that protective top layer of the
skin called the stratum corneum so it
doesn't have as much prot protecting it
as the rest of your body does and we do
see skin cancers on the lips and when we
remove them it can actually affect the
function of your mouth and so a lot of
people don't even think to put sunscreen
on your lips but when you're at the
beach especially if you're prone to
getting sunburn you should really
actually put on a sunscreen lip balm
next up X Tina BB asked can Dermatology
Twitter give me some good skincare
reacks wearing an n95 all day has my
skin breaking out and it's already a
little oily at Baseline SOS yeah this is
a big problem that I saw throughout the
year is just mask related issues and
that a lot of people contributed it to
mask acne specifically but there was
this other side of the coin that was
mask irritation so just having that mask
on your skin all day rubbing up against
your face and also trapping moisture on
your face was actually really irritating
the skin so there's basically two
different piles you can choose from if
you have true acne where your pores are
clogged and you have inflammatory bumps
on the skin I highly recommend not
wearing makeup underneath your mask wear
nothing under The Mask that's actually
going to clog your pores because if you
do it's actually going to make acne
worse another thing is you didn't have
acne before so you may consider adding
an acne treatment to your routine so
something like adapalene or salicylic
acid or benzil peroxide those are going
to be your three top ingredients for
treating acne over the counter consider
adding one of them not all of them
because that can make irritation worse
now if you have irritation to the skin
you're going to want to change your mask
out frequently use softer masks maybe
use fabric masks you know change up that
regimen and then overnight moisturize
use zinc oxide paste that help to repair
the Skin Barrier so two different camps
you have to pick which Camp you're in
and then Target the treatment at that
Redbeard lull asked I have a pretty bad
cracked heel from the bad skin should I
go to a foot doctor or a dermatologist
this is a good question because in
medicine we always look at okay you have
the heart doctor and they deal with the
heart and then you have the kidney
doctor and they deal with the kidney
when truly our bodies are all one piece
right so you have to really look at it
from a holistic approach so you
definitely have overlapping fields and
so when it comes to Foot Care
Dermatology and Podiatry definitely
overlap so your foot doctor is your
podiatrist I would prefer that you would
see your podiatrist because I'm
personally not not interested in seeing
everyone's feet but we definitely treat
foot conditions in dermatology
especially cracked feet you can
definitely see a podiatrist will both
treat you probably equally as well one
of the things that I highly recommend
for anybody that has that cracked dry
feet so any that has ammonium lactate or
Ura in it very effective at moisturizing
and also exfoliating that thick and
cracked heel all right that wraps it up
I hope you learned something I know I
learned something from all of your
questions if you have more questions
make sure to hit Twitter and we'll see
you next time
