UVA related values ​​are more complicated, because different countries have different representations. For example, PA (Protection Grade of UVA) is Japan's UVA filter and protection specification. The number of plus signs behind PA means popular database that the skin can be tanned after use. time. PPD (Persistent Pigment Darkening) is the EU's UVA filter and protection specification, which symbolizes the degree of tanning that persists after 24 hours of UVA exposure. The more numbers behind the PPD, the higher the protection level. Also because SPF, PA and PPD pay attention to different parts, when choosing sunscreen care products, you can't just look at one or two of them, but three kinds in parallel. When choosing sun care products, pay attention to the SPF factor and the plus sign behind the PA are only basic skills. You must look more closely to see if there is a UVA symbol wrapped in a circle on the package. The so-called UVA circle is the sun protection ratio recommended by the European Commission (SPF/PPD≤3), which meets the standards of the European Commission before the UVA logo can be added to the product packaging, which means that the sunscreen has an average resistance to UVB and UVA. , without particular emphasis on anti-UVB or UVA, is one of the indicators of good sunscreen products.
