3 It Can Be Too Late to Start Wearing Sunscreen. 想要開始涂防曬霜時可能為時已晚。

The cumulative effect of the sun's rays causes a multitude of damage to skin, but it's never too late to start protecting skin from the sun. There is clinical evidence that once you start protecting the skin, it has the ability to repair itself. This repair is not going to happen overmight; it's a gradual process that can take a couple years to yield significant results. Do your skin a favour and start the day with a layer of sunscreen. And remember to wear sunscreen during the winter. Just because you don't feel the sun's rays, doesn't mean its harmful UVA and UVB rays are not penetrating your skin. If you can see shadows, you need to protect your skin.
日積月累的日曬會對皮膚造成嚴重損害，但是什么時候開始讓皮膚避免日曬都不晚。臨床證明，一旦你開始保護你的皮膚，它就擁有了自我修復能力。這種修復不會在一夜之間發生；它是一個循序漸進的過程，可能需要幾年時間才產生顯著效果。幫幫你的皮膚吧，涂上一層防曬霜再開始一天的生活。此外，在冬天也要記得涂防曬霜。就因為你感覺不到陽光，并不意味著有害的紫外線A和紫外線B不會滲透到你的皮膚中。如果你可以看到影子，你就需要保護你的皮膚。
