Good protector for your skin

Do you know with is SPF(Sun Protective Factor)? What is PA (Protection Grade of UVA)? Let’s give you some brief idea. SPF is to defense UVB and PA is for the UVA protection. For the sun block products, the PA is mainly use among the Asia especially in Japan.

There are 2 main type of the sun block, the chemical and physical barrier. For the chemical barrier, it contains some chemical substance that will form reaction when the UV rays enter the skin. The chemical substance will break down the UV particles. Some people will have allergy reaction for this. For the physical barrier, the main ingredient is Zinc oxide or Titanium oxide. Both of them act as a shield on top of your skin and reflect the UV rays. So no chemical reaction inside your skin that will cause allergy reaction. For kids, sensitive skin, after skin treatment like laser/peeling/IPL is recommend to use the physical barrier.

For the SPF, it’s an indicator that can resist the UVB ray for how long. 1 SPF =10mins. For example, SPF 30=300mins (6hours) of protection. Many people like to use some product with very high SPF >100, that really not good. The higher the SPF, the more the chemicals inside. So just choose that one that’s good enough for you

For the PA, the more the + is better. There are 3 grading, PA+, PA++, PA+++. The dermatologist is recommenced to use at least PA++ for Asian.

For the application of sun block, you have to apply it 30mins before you expose to the sun and should reapply it every 2 hours, or after lots of sweating or after swimming. As the ozone is getting thinner, it’s better for us to use the sun block as daily use. So choose your own sun block and use it when you are going for any outdoor activities or just simply walking under the SUN.

The UV index and the Sun exposure level:

0 – 2 


3 – 5 


6 – 7 


8 – 10 

Very High

Love to play under the SUN

Finally having a sunny day. I really don’t like rainy day, last week is terrible, the whole week was raining, even having black rainstorm warning signal. I hate the rain and mud that make my clothes with stains, so keep wearing the dark colors clothing for the whole week. Dark clothing with the cloudy sky, really bad mood week~!!

I love the walk, play and go hiking under the sunny day with the blue sky. But before I go out every day, I must put on the sunscreen. Since the skin cancer is getting more popular, this is the way to reduce some risk.

Everyone want their faces to look younger, the ultraviolet (UV) ray is the main element that made your skin look older. There are 3 kind of UV rays, most people might know the UVA and UVB, UVC is present but most of it couldn’t penetrate through the ozone layers. Do you know how did the UV ray been discover?? It’s not discovered by any scientist or doctor. It’s noticed by clerks who sit next to the window for the whole year. He noticed that his right arm which is close to the window, getting darker and start having some aged spots.  So he started to figure out what made the difference between the 2 hands. That’s how the UV ray was found out.

For myself, I’m using the skinceuticals sun block with SPF 20 daily. It’s very nice for sensitive skin because it’s having zinc oxide. The zinc oxide acts as a physical barrier to reflect the UV ray from your skin and won’t cause any reaction inside your skin. Just like putting on an invisible protective clothing, it can be use for kids too. Want to know how to choose a sun block that’s suitable for U, talk in details later~!!
