老生常談，你的防曬霜用對了嗎？

(HealthDay)—Stick or spray-on sunscreens are essential tools against skin cancer, but it's important to use them the right way, a dermatologist says.

皮膚科醫(yī)生告訴我們，涂防曬霜或噴防曬噴霧在一定程度上有利于預防皮膚癌，但僅知道這一點卻是不夠的，知道怎么正確使用也是很重要的。

Wattenberg is an associate clinical professor of dermatology at the Icahn School of Medicine at Mount Sinai in New York City. "Sticks are easy for under the eyes and the backs of the hands, while spray sunscreens are often easier to apply on children," Dr. Debra Wattenberg said in an American Academy of Dermatology news release."However, it's important to take precautions when using stick and spray sunscreens to ensure the best protection for you and your family," she added.

黛布拉 · 沃滕伯格博士，是紐約市西奈山醫(yī)學院皮膚科的臨床副教授。她在美國皮膚病學會的新聞發(fā)布會上說:"當我們要在眼下或者手背上涂時，用防曬霜棒更好;對兒童來說，防曬噴霧更友好。但不論怎么使用，安全問題不容忽視，你必須采取一定的防護措施，這樣你的家人和你才能得到更好的保護。”

As with lotion sunscreens, choose sticks and sprays that are broad-spectrum, water-resistant and have an SPF (sun-protection factor) of 30 or higher, Wattenberg said.

她還說到：“不論是防曬霜棒還是噴霧型的，必須滿足防水、廣譜防曬，且防曬指數(shù)必須達到30及以上。”

When using sticks, apply four passes back and forth on each area of skin to ensure ample protection. Then, rub the sunscreen in so there is an even layer of coverage.

用棒涂時，必須要來來回回涂個四遍，這樣才能形成足夠的保護，再涂防曬霜，就又可以多加一層覆蓋;

When using sprays, hold the nozzle close to the skin and apply generously. A good rule of thumb is to spray until the skin glistens. Rub the spray in thoroughly to ensure there are no uncovered spots and coverage is even, Wattenberg said.

使用噴霧時，將噴嘴貼近皮膚，盡管噴別心疼。那怎么樣才算是噴好了呢?一直噴到皮膚有點反光才可以。沃滕伯格說，你需要徹底擦拭噴霧，確保沒有發(fā)現(xiàn)抹不開的斑點，也不存在沒覆蓋到的區(qū)域。

Never spray sunscreen near your face or mouth and do not inhale it. Spray your hands first and then use them to apply sunscreen to your face.

永遠也不要在臉上附近或者嘴邊噴防曬噴霧，以免吸到嘴里。你可以先多噴下手，然后再小心地涂抹在臉上。

Don't use spray sunscreen on windy days because it's harder to apply and there's a greater chance of accidentally inhaling it. Never apply a spray sunscreen near heat or an open flame, or while smoking, and make sure it's thoroughly rubbed in and dry before going near open flames.

假如某一天風很大，最好也不要涂抹防曬，因為這種天氣本來就不好涂抹，再加上你吸入口里的可能性也更大。此外，也千萬不要在接近高溫或者明火的地方涂抹防曬霜、噴防曬噴霧，吸煙的時候也涂抹不得，你還必須在接近火焰之前，把防曬霜徹底擦干。

"No matter what type of sunscreen you use, make sure you reapply it every two hours when outdoors or immediately after swimming or sweating," Wattenberg said.

瓦滕伯格說：“最重要的是，無論你涂了啥樣的防曬霜，在戶外呆了兩小時之后，游泳甚至是出汗之后，都必須重新涂一次。”
