教您应怎样避免阳光灼晒一

Using sunscreens
It is one of the most important ways to protect your from the strong sunlight. You'd better use sunscreen 15 to 30 min. before going outside. It should be applied on all exposed skin, which includes lips, nose, ears, neck, hands, feet and eyelids. Try not to put it in the eyes because it can irritate them. You also need to note [1] that before or after swimming, you need to apply the sunscreen on your skin, because the sun's rays can pass through the water easily.
