well hey guys welcome back to the QA so
you know the temperatures are dropping
probably getting very cold depending on
where you live in the world and this
week I wanted to talk about dry skin on
the Friday QA I think it's appropriate
for the time of the year and I hope to
share with you guys some of my favorite
moisturizers in a video later next week
so stay tuned for that but today I'm
going to be talking about dry skin on
the body and dry skin during the
wintertime how to deal with it and that
sort of thing if you're new here welcome
my name is Andrea I'm a dermatologist I
post fun day-in-the-life blogs as well
as some fun recipe and lifestyle videos
but my content is largely skincare
focused and I do a weekly QA on a sink
care topic of interest as well as review
a lot of skincare products their
ingredients and that sort of thing so if
this type of content is of interest to
you I encourage you to stick around and
check it out
so you know I've talked about this
before on the channel but if you think
about your skin is sort of like a bed
and you have a mattress that corresponds
to the dermis or the deeper layer of the
skin and then you have all of your
bedding on top your quilts your linens
and that sort of thing and the quilts
and linens on the top are similar to our
epidermis okay they're sort of a
different layer of our bedding so to
speak and dry skin occurs when the very
very top layer of the skin the stratum
corneum the very top layer of the
epidermis becomes too water deficient
okay and it has lost too much water and
that results in the in the stratum
corneum kind of having a dull appearance
being flaky and and dry and predisposing
to cracked skin fishers and bouts of
itchy skin the function of our skin is
is to form a barrier and to keep you
know fluids it in but as it becomes dry
it becomes a little bit compromised and
it starts to lose water more readily
that's called trans epidermal water loss
okay and you know the medical term for
dry skin we have all these fancy names
for it like cirrhosis XE OSIS a
steatosis but you know I think at the
end of the day we all have at least
dealt with dry skin at some point in our
lives it's quite a common and prevalent
skin concern it you know it can if it
affects men and women of all ages it
doesn't have a gender predilection since
this video is not you know just for
women skin care is for men and women so
hopefully that message is clear to you
guys out there watching but there is a
little bit of racial variability and
that certain ethnicities may have a
predisposition to dry our skin and this
predisposition reflects some subtle
variability in the lipid content of the
top layer of the skin not only the lipid
content but also some of the proteins
that make up our top skin barrier
one such protein is something called
fill Agron dry skin can start at any age
but people who may have a little bit of
an underlying genetic susceptibility to
dry skin such as people with different
forms of fog Rijn they'll develop dry
skin very very early in childhood so you
know depending on your family history it
may be something that you've played been
plagued with all of your life or merely
episodically as a result of your
environment if you have atopic
dermatitis or eczema you're also
probably intimately familiar with dry
skin it's a cornerstone of the eczema
features unfortunately and you probably
are well aware of the fact that keeping
it on top of your dry skin is essential
to prevent flares of your eczema and
bounce of itchy inflamed
Raschi skin on the body that can be
quite uncomfortable another ingredient
if you will in in this skin barrier or
something called ceramides that can
become a little bit deficient just with
time and chronology of age and so much
so that nearly everyone
over the age of 60 is going to be
dealing with dry skin okay so you can
see how this is quite a prevalent issue
there are also certain diseases and
conditions that unfortunately are
associated with we're very very stubborn
dry skin I think it postmenopausal women
out there well relate to this but after
after menopause because of some of the
hormone changes in the body that
normally kind of drives some of the oil
production that keep our skin hydrated
