**World's best sunblock**

This is my favourite sunblock ever after i tried more than dozen of sunblocks....perhaps the words MADE IN JAPAN really convincing....hehe^^

It is a sunblock which is non greasy at all and most important it able to moisturize your face!

Biore claimed to have SPF50+ PA+++, meaning that it is one of the highest sun protection value in the market after Sunplay SPF130.....but actually, you can notice there are a "+" after SPF50 in Biore, this is because Japan Health Ministry had made a law stated that no sunblock can label more than SPF50, any sunblock higher than that, can add a sign"+"....thus, Biore might be higher than Sunplay, we won't know!!! For your information, Sunplay is a products under Mentholatum, Korea product.

Since nothing to do today, let me tell about some scientific knowledge....hehe....if you feel bored, can just skip this!!! Everyday, we just keep talking about UV, UV and UV, but do you know exactly what UV did to our body???

UV is a type of radiation which capable to cause cancer. The effects on cell include inhibition of cell division, inactivation of enzymes, induction of mutations and in sufficient dosage, death of cells. There are mainly 3 types of UV rays - UVA, UVB & UVC. Among them, UVB is the most dangerous, as it is carcinogenic. In the other word, it responsibles for most of the skin carcinoma for instance basal cell carcinoma, squamous cell carcinoma, and melanoma! How it affects the cell? It is attributed to its formation of pyrimidine dimers in DNA and sometimes it will cause mutations in p53 and RAS oncogene....UVA won't cause severe harmful effects while UVC though is mutagenic but fortunately it is filtered by ozone layer....however, in case the ozone layer deplete, then "cham" lol!!! Perhaps it quite complicated for understanding, to explain in the simple way, 95% of them are UVA, it radiates in a high proportion whole day long, causes melanin accumulation, thus form dark spot and aging ; UVB in fact causes redness and swelling, and most of the symptoms shown after went to beach, they will radiate in large amount from 10am to 3pm.

So, whenever you go and buy sunblock, you can see the label SPF and PA. SPF means sun protection factor, protect you from UVB. PA means protection factors of UVA, this measurement is officially released by Japan cosmetic company. As you can notice, most of the Japan brand will labeled both SPF and PA, while Europe products will merely have SPF and some will put PPD. Don't worry, SPF normally will range from 15 to 50....it means how long you can stand to the sun, before you get sunburn. You can calculate it by simply adding a zero and convert it into minutes. For example, if you're using SPF 15, meaning that you can stand under the sun for 150minutes. PA will be valued by the amount of +, as by now, the max is +++.
This is the indicator:-PPD 2~4 is PA+
PPD 4~8 is PA++
PPD 8 above is PA+++
So, whenever you wanna buy sunblock, SPF50 PA+++ will be the best right now!

Back to Biore, this waterproof sunblock can instantly radiance your skin and cover up minor pores! Almost the same texture with Mentholatum Sunplay Range, what we called "Liquid Paper", Biore consists of powder which can absorb oil and cause the skin looks smooth, just like the effect of foundation, but it don't looks like makeup! This product also easy to spread out through the face and won't feel sticky even apply twice on your face! This sunblock need makeup remover to remove in order to get rid from blackhead and whitehead thingy! If possible, I'll recommend a nice makeup remover tomorrow.

Last but not least, give all of you some tips while buying sunblock, just shake the sunblock, and if there are "guli" inside, just like liquid paper! Then, that's a good sunblock!!!!

Whitist forever!!!!
