so a few months ago we did a responding to your comments video on how to treat sunburn
the videos done really well and I think we probably had over a thousand messages
of people asking me, Abraham what sunscreens do you recommend?
so you asked for it and you got it but before we begin I just want to tell you this
one thing I know that youtubers are often approached by many companies to
endorse or recommend their products I'm also approached by many of these
companies as well but I do feel it's unethical of me to do this so what I'm
not going to be doing in this video is recommending you a certain product but
what I will do is I'm going to teach you how to protect yourself from the Sun and
I'm also going to teach you what to look out for what ingredients to look out for
and how to pick the best sunscreen from any pharmacy so without further ado
let's begin I'm gonna go to work and I'll see you there
so for us to understand sunscreens we first need to understand how our skin reacts to
ultraviolet light and to do this we use something called a fitzpatrick skin type
scale which should pop up now have a look at it maybe pause the video and
determine which skin type you are I would classify myself as a type 3 now we
will come back to skin types a bit later on in the video but first let's learn
about sunscreen so sunscreens can contain two agents known as chemical
absorbers and physical absorbers now chemical absorbers are more commonly
found in sunscreens and the way they work is by converting UVB radiation into
heat physical absorbers however aren't commonly found in sunscreens and they're
insoluble pigments found in the sunscreen and when you apply it, it forms a non
transparent layer on the skin physically blocking both UVA and UVB radiation so
how do you check if your sunscreen has a physical blocker well it's pretty simple
just read the ingredients with things like zinc oxide and titanium dioxide
they're basically your ingredients that are physical blockers but remember this
generally speaking when a sunscreen has a physical blocker it is a little
thicker to use and it also may leave a white layer on your skin I don't mind it
many people don't but it's good for you to know that okay so what about
SPF stands for Sun Protection factor and it describes the protection you
get against burning from UVB radiation so it tells you how long you can stay in
the Sun without burning now let's say your sunscreen is SPF 15 and you can
usually spend about 10 minutes in the Sun without burning now by applying an
SPF 15 sunscreen it's going to mean you can spend 15 times longer in the Sun
without burning so 15 multiplied by 10 minutes duration which you're good with gives
you 150 minutes in the Sun without burning but the question is how accurate is SPF
is it an exact science well I'm afraid it's not because what SPF doesn't do is
it doesn't take into account many different variables
so one example is the intensity of solar radiation so this can
differ at different times of the day different seasons and also the
reflection of solar radiation off surfaces so where are you are you on
water are you on snow are you on sand all of these can have a massive impact
so SPF protects against UVB radiation but what about UVA radiation it doesn't
cause burning but it does cause skin ageing wrinkles and skin cancer now UVA
protection is classified by a star rating and I don't actually think many
people are aware of this and I do think that the sunscreen manufacturers should
make this more visible so everyone's aware so you have star ratings of one to
five, one gives you about twenty to forty percent protection against UVA radiation
and five star which is the best gives you about 90 to 100 percent protection
against UVA radiation so you now know how sunscreens work about SPF and UVA
protection but which sunscreen should you get which is the best well generally
speaking you need to go for a sunscreen with an SPF of 30 and a UVA protection
of 5 stars but do you remember the fitzpatrick
scale that we spoke about at the start well the reason I mentioned this is that
if you are an adult whose skin type is one that burns very easily then it may
be more appropriate for you to get a sunscreen with a higher SPF now in terms
of application you need to be applying a quantity of 6-8 teaspoons worth of
sunscreen at least 30 minutes before going out in the Sun you also need to
reapply at least every two hours you might need to reapply more often
if you're getting wet and it's getting washed off so normally I don't like to be the
healthcare professional who's all doom and gloom but getting sunburned is very
serious and getting it just once every two years
triples your risk of melanoma type skin cancer so I can't stress the importance
enough that you protect yourself from the Sun you protect family your loved
ones even tell strangers if they're not doing things right and let them know
because you're protecting them too also by the way getting sunburn
doesn't just me when your skin is red and peeling off sunburn is also
classified as when your skin is pink when it's red when it's irritated all of
this is also sun burn there's also many of the things that you can do to protect
yourself from the Sun such as wearing loose-fitting clothes wearing a hat
spending more time in the shade and not going out in the Sun between 11 a.m. to
3 p.m. when the Sun is most intense also don't forget to wear sunglasses and
wear a lip balm with an SPF I'll actually leave a load more information in the
description below which I'd recommend everyone to read on protecting yourself
from the Sun okay and I guess now you are a sunscreen pro so welcome to the
club enjoy buying your product you now know what
to look out for you now know what to get and you can even impress your friends with
all your new knowledge have fun stay safe and I'll see you next week
SPF, SPF (Phone beeps)
always beeping is this phone always beeping with your comments well that was
watsap actually so I did tell a lie there but a lot of times it's your comments
five star rating well that's ten star (Laughter)
many different variables one example for example, for example (Laughter)
