In the previous article, we have discussed why to protect your skin from 
UVA and UVB  rays and some important knowledge about sunscreen gel – 
for sun protection.
Here we come up with part -2 of this article, we will discuss more on gel 
sunscreen for  face and why it’s soo important. Let’s 
get started, if you miss reading the part – 1 click  here to read.
How and when to use Gel sunscreen
It is important to remember that the thickness of the sunscreen layer you 
applied is the
whole essence of protection from the sun. This is why it’s important you 
should know how  to use it.
Gel sunscreen should be applied to all treatments and before makeup (if you 
use it). It is  because it must be applied on top of the care. After all, if you 
spread a regular cream on  top of the sunscreen layer, you will rub the 
protection layer, and it will not be uniform.
And because moisturizing will not reach the skin through makeup. Mke sure 
Makeup  should be applied over Sunscreen because what’s the point of 
applying some other  cream on top of the foundation? It will smear. The 
essence of makeup is that it is on the  surface of the skin.
Foundations do not destroy protection because filters absorb radiation and do 
not need to  be on the surface. Analogy: if you wear a T-shirt over a sweater, it 
will not destroy the  sweater’s warmth.
Between applying Sunscreen and makeup, it is better to wait 5-10 minutes to 
dry and fix  the Sunscreen, so the protection becomes more reliable. I usually 1/4
don’t wait for that  much. Time in the sun damage.
Apply it with patting movements for the makeup to damage and break the 
protection layer  as little as possible. There is no need to wait between the 
application of the care and the  Sunscreen, but evaluate what can presumably 
happen.
For example, if your skin care product is wet and greasy and the layers mix 
upon  application, you don’t get an even thick layer of uv protection. So it 
is probably best to  wait until the care is absorbed.
A little about makeup with SPF, day creams and sunscreen 
sprays
Decorative cosmetics rarely have a sun protection factor above 15 and even 
less often  protects against UVA radiation. Therefore, even if your foundation 
has a sun protection  factor SPF of 30-50, you will never apply the foundation 
or powder needed for complete  protection.
It also applies to bb- and cc-creams. Therefore, I ask you not to rely 
on filters in  decorative cosmetics and to use a separate sunscreen.
The same goes for SPF 15 day creams. As for the sprays, they are practically 
useless as  the main protection.
It is impossible to create good coverage with them. Most of the product 
settles on all  surrounding surfaces, is blown away by the wind and, most 
unpleasant, and is inhaled.
And even if you use Sunscreen in a spray, you need to rub it with your hands 
and not just  leave it sprayed on the exposed skin. Sprays can be used to 
renew the protection on the  face over the top of the makeup. It’s the same 
with powders.
What happens if you use a Gel sunscreen SPF 50?
The ability of a medium to absorb light depends on the wavelength of the 
absorbed wave  and the concentration and thickness layer of this substance. 
The law is stunningly  obvious, and in theory, if you mix the two, the result is 
a protection factor that equals  something in between.
As you probably already know, not every theoretical calculation works in 
practice.
First, the SPF value does not directly depend on the concentration of the 
filters. There are  thousands of factors that determine the value. Not to 
mention that the filters are contained  in the base of the cream, and it dilutes 
the concentration.
Secondly, the SPF indicated on the package will be the same if you smear 
the  recommended 1.25 ml only on your face, and few people smear that 
much. As a result,  how much protection you have there is unknown, but 2/4
less than what is written on the  bank. Therefore, no one can tell which SPF 
values you are layering.
But if you layer two creams, then the SPF value is likely to increase simply 
because the  layer gets thicker. The main thing is to try not to mix them but 
to layer them.
Gel sunscreen and vitamin D
Of course, the sun plays an important role in the synthesis of vitamin D. But 
using broad  spectrum sunscreen does not cause vitamin D deficiency for 
several reasons:
No sunscreen protects 100% from the sun.
Few people put on so much Sunscreen to provide the best possible 
protection.  To get the required amount of vitamin D, you need to be 
in the sun for 10-15  minutes a day.
What’s more, Sunscreen helps maintain proper vitamin D levels because 
people are not  afraid to be in the sun with it. Several materials:
A study shows that people who protect themselves from the sun by 
wearing closed  clothing and sitting indoors have a risk of vitamin D 
deficiency, while those using
Sunscreen do not.
Two – an Australian study with a control group that no person was vitamin D 
deficient in  Sunscreen. Not a single one.
Three – a study that Sunscreen can only slightly reduce the synthesis of 
vitamin D., But  this does not affect the overall level and health.
Four is a great overview of the issue, which has brought up virtually all of 
the existing  research on the topic. But, no, there is no link between 
Sunscreen and vitamin D  deficiency.
Final recommendations
Choose a cream with an SPF of at least 30 or higher
It must be labeled with UVA protection, depending on the country of 
origin.
For sensitive skin, choose inorganic filters because they are less likely 
to cause  allergies.
Apply gel sunscreen half an hour before sun 
exposure  Reapply sunscreen after every three 
hours.
Remember to wear ear protectors and the back of 
your neck.  Sunscreen is always the last step before 
makeup.
Wait for the Sunscreen to dry and absorb before applying the 
foundation. It usually  takes no more than 10 minutes.
It is possible to apply the tone over the Sunscreen, but it is better 
with patting  movements or a sponge.
Update every two hours if you are outdoors.
If you use persistent Sunscreen, then wash it off as permanent 
makeup. If your  Sunscreen is not persistent, wash it off as usual.
Avoid the open sun whenever possible, even if you are covered with 3/4
protection.
