Sun rays can cause many damages to our skin in
many ways. It can cause sunburn, skin cancer and
many more. Thats why it became important to
apply extra protection on our skin to protect
from sun rays. Here comes best sunscreen gel or
cosmetic with SPF. There are many ways to get sun
protection get to know which one is best for
you. Why protect yourself from the sun at
all Solar radiation is the very first and
foremost factor in aging and skin cancer. The
sun rays damage to the DNA of skin cells, and
tanning is a defense against damage that
prevents further damage to the cells. This damage
can result in carcinoma and melanoma. Even the
lightest tan damage skin. Safe tanning is an
oxymoron. Do not try to convince me, yourself,
or anyone else that sun and light tanning are
beneficial. If you like sunbathing, please
sunbathe. But there is no need to say that it is
safe. Here I will also include highly frivolous
opinions that the sun heals the skin and, in
particular, acne. The sun helps the skin look
better by darkening it, but ultimately it only
aggravates skin problems. You need to protect
the skin of any color and any origin. If you have
dark skin that hardly burns, this does not mean
that you do not need protection. It is essential
to protect children, including babies, from the
sun. Dont be fooled by stories that sunscreens
are bad for childrens skin. Their skin can be
sensitive to certain filters, just like adults.

UVA vs. UVB Solar radiation (UV radiation) is
divided into UVA, UVB, and UVC. The latter
remains in the atmosphere, while the first two
reach our skin and damage it differently. UVB
rays have a 290-320 nm wavelength, and UVA rays
have 320-400 nm. Read to know Why should you
Wear Sunscreen GeL UVA rays penetrate the skin
deeper than UVB and play a critical role in skin
aging. Sunburn also appears mainly due to these
rays. They do not cause visible signs of
damage. That is, they do not produce burns.
Damage from UVA radiation builds up over the
years, and if you sunbathe well on vacation as a
teenager, then after 30, you should not be
surprised at age spots. UVA radiation causes
mutations in cells and also contributes to the
development of skin cancer. The intensity of
UVA radiation practically does not change
depending on the season, weather, and time of
day (except at night, of course). UVB rays do
not penetrate deep into the skin and are trapped
in the epidermis. And they are the ones that
cause burns. They also play the most critical
role in developing skin cancer and only
partially provoke photo-aging and sunburn. But
they are responsible for the production of
vitamin D. These rays do not penetrate glass and
clouds, and their most excellent activity occurs
in May-October from 10 am to 4 pm. SPF factor
in best sunscreen gel The SPF number shows how
effective a product is in protecting against UVB
radiation. Not UVA or full spectrum. The higher
the number, the more radiation it blocks. From
this graph, you can see that between SPF 30 and
50, the difference is only a couple of
percent. But this is only if you apply them in a
thick layer, and few people use them. And even in
this case, a higher SPF sunscreen gel protects
better. When applied in a thin (usual) layer, SPF
50 protects much better. Skin that has no
protection takes about 20 minutes to get
sunburned. SPF 15 increases this time 15 times,
that is, up to five hours. In other words, the
factor needs to be multiplied by 20, and you get
the time that you can safely be in the
sun. Because SPF is not an indicator of time,
but of the amount of radiation that your skin
with cream can withstand, compared to bare
skin, different skin needs different amounts of
radiation to burn. And the amount of radiation is
highly dependent on the UV index on
3
each specific day. In sunny, cloudless weather,
much more radiation will fall on your skin per
unit of time than in cloudy and cloudy ones. UVA
Protection To understand whether your cream
protects UVA, you need to look for specific
markings. In Derma Essentia best sunscreen gel,
contain PA (a different number of pulses
depending on the degree of protection) The broad
spectrum mark (means that the Sunscreen protects
against UVA in the same way as against UVB) The
UVA icon in a circle (means that the degree of
protection against UVA is at least 1/3 of the
SPF indicated on the package). How much
Sunscreen to use According to dermatologist, you
need to apply 2 mg of the product per 1 cm2 of
the skin. It is 1.25ml for the face only. This
amount ensures that the protection is as
indicated on the packaging. The number was
taken from experimental data. It is the amount at
which any sunscreen works on any skin. How much
it is by eye can be seen here. A lotion of
medium consistency is about half a teaspoon on
the face and neck and a tablespoon on all other
body parts. For the whole body with a minimum of
clothing, you need about 30 ml of cream. It
would help if you had more liquid lotion and less
dense thick cream. But the volume can vary
depending on the density and texture of the
product. And it also, of course, depends on the
area of the face. You can try to calculate the
location of your face and calculate how much you
need. I counted and found out that I needed 0.8
ml for my face. How to measure is written here.
According to research, most people apply half or
even a quarter of the amount they need. Yes,
when applied at 2mg / cm2, all sunscreens above
SPF 30 will protect about the same. But few
people use so much, and here sunscreens with a
higher SPF (50-100) are better protected because
a higher SPF, to some extent, can compensate for
the disadvantages of application. The question
logically arises why not make the best sunscreen
gel that works when applied in a thin layer?
Because the coating must be even, and it isnt
easy to apply a thin layer evenly. Thick is much
easier. To make things easier for yourself, use
this rule of thumb Apply two regular coats of
Sunscreen and be sure to wait to dry between
applications.
