Do you know UV-A is the intensest in May?!

         In May, there are so many kinds of dangerous rays from the sun. Among those, the Ultraviolet A (UV-A) is the intensest. It can get through window glasses reaching inside your skin. If you continue this ray-bathing, deep dark spots, freckles, wrinkles, etc. will appear on your skin.  Moreover, UV-B, which immediately gives you an inflammatory after bathing, is also increasing in this season. These rays can follow you wherever you go; under the shade, even when you turn your back towards them. This is because there are scattered rays from the Sun. Therefore, you may need an effective sunscreen to help!

         “SPF” and “PA” are signs indicating the efficiency of the sunscreen you use.  “SPF” means the protection against the UV-B. The higher it is, the more it is efficient. In the case of showing “SPF more than 50”, there will be “50+” instead. For everyday life, SPF 20 is enough. For outdoor soft sports is 30, whereas for a strong one should be 50 or over. 

         “PA” is the [+] sign telling how much it can protect you from the UV-A.  The more there are + sign, the stronger the protection is. For everyday life, PA + is enough. For outdoor soft sports is ++, whereas for a strong one (marine sports etc.) should be +++ or over. 

         And if you plan to get into a swimming pool or the sea, do not forget “water-resistance” type and re-apply every 2-3 hours. Follow these instructions, and then your skin will keep freshness, brightness, and healthiness!!!

Comment:    I am also a person who takes care of the skin and hate the strong light. Hahaha However, it is so shameful that I did not know the meanings of one of those signs before. I think many people are like me. They surely know SPF, but do not really care the PA + sign. Nonetheless, it is the real time to look after our skin from now on!!!
