In an age when our phones are also our wallet, watch and GPS, I expect intelligent, multi-tasking efficiency from everyday skincare as well, especially SPF(sun-protection factor).
About Sunscreens
■Wear SPF daily. It helps protect against not only sunburn but also almost 80 percent of the skin and ageing problems. Meanwhile, remember to prevent skin from drying after the use of sunscreen since skin needs moisture (水分).
■Choose an SPF number based on length of time in the sun and the intensity of the sunlight. SPF30 lets about three percent of UVB ray s through;SPF50 about two percent.
■Understand the difference between chemical (or “organic”) and mineral (or “inorganic” physical) sunscreens. Chemical sunscreens tend to be more lightweight and less oily, which absorb UV light (紫外线). Their composition causes a reaction where light is changed into heat and then gone. Mineral sunscreens, meanwhile, act like a barrier. Active ingredients protect from UV rays, and sit on the surface of the skin, reflecting the sun’s rays. These are generally thicker in property and can leave a white cast.
Application tips
■Apply enough:about a shot glass for the whole body and about a quarter teaspoon (1.25ml) each for face and neck. No less for high SPF.
■Apply at least 20 minutes earlier before heading outside and reapply every two hours (more if you are swimming or sweating).
■Don’t miss the hairline, ears, front and back of neck.
■Make-up with SPF is not enough for sun protection. Layer it on top of sunscreen.
