Hi,
everyone.
Super today's video.
We're going to be investigating the question.
Does sunscreen really work?
Before we can answer this question,
it is important to understand how this plan can affect
your skin is going to mix ultra violet radiation,
which is almost 95% UVA radiation.
This is a primary type of radiation that causes wrinkles
and can trigger carcinogenic affected by cancer.
There is also UVB radiation.
The difference between the two is their way fun.
UVA has a longer wavelength and is therefore more damaging
because it can penetrate the deeper layers of the skin.
Now,
let's say you wanted to relax at the beach and
tan,
you would be exposing your skin to both these types
of radiation.
This will cause the skin cells to produce a factor
called melanin,
which is a pigment found in your skin.
A longer one is exposed to the Sun,
the more they can,
or the more melanin in their body.
Produces your body,
tries produces melanin,
as a protective measure melanin helps to protect the surface
layer of the skin called the epidermis and it does
so,
but absorb UV lights before the radiation can penetrate the
Beeper to DNA of the skin cells.
15 acres to skin cells.
Are not able to reproduce as effectively nor can they
produce a skin benefiting factors?
Like halogen,
which is a protein that helps maintain from this in
the skin.
Decrease collagen production means decrease skin,
elasticity of the formation of wrinkles UV radiation can cause
mutations to occur in the skin cells undergo and reproduction
occurs,
DNA says cells are more likely to become cancerous as
they are unable to self-regulate.
That thinks that your skin is limited in the amount
of media rate they can absorb in a given.
Of time.
This is wear sunscreen can help,
but providing that extra layer of protection.
It works in a couple different ways depending on the
type of sunscreen,
you're wearing green organic
compounds that contain carbon on the other hand.
If you choose to wear,
your sunscreen probably has either titanium dioxide or zinc oxide
in it,
but will get is the different types of sunscreens later.
Now,
do you understand the basics of how the Sun can
be harmful to our skin?
Let's get into others videos,
really about the screen as mentioned before.
There are two main types of sunscreen chemical and physical
physical.
Sunscreen can contain either a titanium dioxide or zinc oxide
and this type of sunscreen work,
similar to a mirror,
it will reflect and Scatter the UV rays as they
come in contact with the skin.
Physical sunscreen to have to tanium dioxide or zinc.
Oxide as their main component,
tend to be less soluble and liquid meaning that if
your Clues any chance dermal,
absorption of more than the minimum balance regardless of concentration,
information on product,
given that these two elements are insoluble.
I'd only active and do not penetrate into skin or
enter into the systemic circulation to any meeting books by
the FDA,
consider the available data on titanium dioxide and zinc.
Oxide adequate enough to approve it and allow it to
be used in sunscreen formulation.
Currently,
It is believed that the difference between titanium dioxide and
zinc oxide,
is that titanium dioxide Khomeini?
Absorbs use Easy life where I think outside of the
UVA.
So,
as you can imagine,
a combination of both would provide broader and more effective
protection chemical.
Sunscreens on the other hand Works differently because they contain
organic compounds.
Chemical,
sunscreens are able to dissipate to absorb UV radiation via
photochemical Pathways involving reactive oxygen.
If
we're at some point in time,
a bit toxic to scan model cells when undergoing testing
in the lab,
this was determined by a few experimental studies and maybe
the reason why some people still hesitate to work on
screen Give me misinformation,
is sunscreen all that necessary but take a look at
what the research says.
Has the primary purpose of sunscreen is a protect people
from harmful UV rays.
Some Studies have been conducted to support
the use of sunscreen daily.
Multiple studies tested.
Sunscreens,
Effectiveness on skin cell tumors.
Specifically basal and squamous cell carcinoma tumors basal cell
carcinoma by the end of the study.
There was enough,
served a 40% decrease in squamous,
cell,
carcinoma tumors,
and those apply sunscreen daily despite the significant impact of
sunscreen and squamous cell carcinoma.
There wasn't much less considerable impact on.
Basal cell carcinoma,
these results support the day today,
used as sunscreen,
in addition to other forms of protection from UV rays.
in other studies,
there has also been overall support for sunscreen what experiment
showed that people exposed to a moderate amount of UV
rays,
and reach a 7.5,
sun protection,
factor or SB,
I will have an 84% reduced risk of basal and
squamous cell carcinoma for 55 years old,
The study has also highlighted the impact of sun exposure
and skin Types.
On a person's risk of skin cancer,
the difference and exposure during childhood and adulthood was described
using the sun,
definitely,
right?
Or SAR at the same time,
skin texture separated,
into four categories based on a person's likelihood of being
tan or developing either basal or squamous cell carcinoma.
Tumors from the grass,
is shows how two different sun protection Factor.
Then Infinity ratio is good type affect and mitigate the
risk and under UV radiation.
Do the benefits of sunscreen on you over some of
the rest sunscreen May impose on human health can be
broken down into three categories,
sunscreen reaction with the skin sunscreen absorption and sunscreen
affect and developmental and endocrine impairment.
Coming to your party reactions with sunscreen are irritations of
skin.
Such as singing burning and clogging up.
Of course,
there any ingredients is censoring such as oxybenzone and oxygen
with oxygen.
And might have also been reported to cause allergic reactions
with the skin but very rarely Who studies sponsored by
the United States Food and Drug Administration have also confirmed
that for sunscreen ingredients,
oxybenzone and Zone after Carlene and the council showed the
stomach absorption blood levels for these compounds were higher than
those advice.
But US Food and Drug Administration standards Wendy's,
compounds were utilized under maximum usage recommendations over for consecutive
days that has had extensive Half-Life.
However,
it is important to note that most people do not
use the music of sunscreen that was used in the
study further.
Research needs to be done to understand if any health
risks are actually associated with a girl version of beat
ingredients,
Leslie.
Recent data suggest that some sunscreen ingredients May function as
endocrine disruptors which could be hazardous to developing organism.
These ingredients have been linked to altered estrogen,
and Urgent and progesterone activity which can lead to reproductive
or developmental toxicity.
And dysfunction there.
Any ingredients have also been shown to cross the blood-brain
barrier and playing in Euro,
toxicity risk.
So based on what,
you know,
now how will you answer the initial question?
Do you find sunscreen to be really necessary?
Let us know what you think in the comments and
thanks for watching.
