If you’re buying sunscreen from a Japanese brand, you’re likely to come across the PA rating system. 

PA stands for protection grade of UVA system and is the Japanese measurement of sun protection, which is based on the Persistent Pigment Darkening (PPD) reaction reading at 2-4 hours of sun exposure.  According to info from the wiki, the Persistent Pigment Darkening (PPD) method is a method of measuring UVA protection, similar to the SPF method of measuring UVB light protection.

If you go round the pharmacies, you must have seen the latest range of Neutrogena Ultra Sheer range consisting of Dry-Touch Sunblock SPF50+, Dry-Touch Sunblock SPF70 and Body Mist Sunblock SPF45 which all come with the patented Helioplex suncare technology.  So what exactly is Helioplex and is it true that it gives up to three times longer UVA protection? 

What is Helioplex?
According to the information I gathered from Neutrogena’s website, Helioplex covers the complete UVA/UVB spectrum by harnessing the full power of two sunscreens, Avobenzone and Oxybenzone. 

Anthelios XL Stick for ultra sun protection

The temperature has been reported to be as high as 30° C and the UV index is at 11 and that is an extreme UV status which calls for ultra UV protection of course!  Definitely an extremely good excuse to get the La Roche-Posay Anthelios XL Stick Protection SPF50+ I say.

Sunscreen before or after moisturizer?

I’ve updated my earlier entry Tips on sunscreen protection & application with a couple more information.  One of which is about when to apply sunscreen in the order of our skincare regime because I noticed that this is something frequently asked. 

Actually I’ve always thought that sunscreen should be applied after using our serums or moisturizer but if you consider that chemical sunscreens absorb UV rays and neutralize them in the skin tissues, then it make perfect sense that they should go on clean, bare skin first because in order to be effective, it must interact with our skin cells.
