Higher SPF The Better? – Pt 4

The easiest way to remember UVA & UVB is ‘A’ stands for aging and ‘B’ stands for burning. To recall back, UVA ray penetrate deeper into skin giving rise to ’progressive’ injuries such as face wrinkles and fine lines, unlike the ‘immediate’ injuries from UVB.

Actually, there is a rating system for the UVA, called the PA rating, but it is not currently recognized by the U.S. FDA. The amount of UVA that reaches earth is actually significant, amounting to >90% and
"Go for the Mexoryl SX, a sunblock produced by L’Oreal and it is reported to be an excellent product and it can block both UVA and UVB and its UVA protection can sustain longer than most other products"
it is capable of penetrating through windows and cloud. This PA system is very common for anti sunscreen / sunblock and not limiting to anti wrinkle cream in Asian countries, particularly in Japan. There are 4 levels of protection: PA, PA+, PA++,PA+++ for the rating system. The more the plus (+) sign, the greater the level of protection and PA++ is the minimum recommended rating.
There are many forms of sunblocks or sunscreens in the market and you can find them in waxes, sprays, or powders apart from the more common lotions/gels. There are cases whereby some people are allergic to the Oxybenzone and PABA and if this happens, try converting to other brands. Which is the most suitable type of sunscreen / sunblock to your skin? Well, it varies very much on individual, as long as it is comfortable and not being too sticky, then it is okay.

 UV light pictureGo for the Mexoryl SX, a sunblock produced by L’Oreal and it is reported to be an excellent product and it can block both UVA and UVB and its UVA protection can sustain longer than most other products. Unfortunately, a few years ago when I checked, the Mexoryl SX is still not available in US soil but already available mostly in the rest of the world. Perhaps you can it now in US.

Info - I have seen some sunscren with SPF rating as high as 130, but you should only opt for minimum of SPF30 as described in Part 2 of this article as anything higher is just inconsequential.
