Lip Balms and Glosses May Boost Skin Cancer Risks
It's the shine that attracts ultraviolet rays, but sunscreen base can help, expert says
| SATURDAY, April 26 (HealthDay News) -- Shiny lip balms and glosses may attract ultraviolet rays and increase the risk of skin cancer, warns a dermatologist at Baylor University Medical Center at Dallas. Dr. Christine Brown noted that protecting your lips from harmful sun rays is as important as using sunscreen to protect your skin. But a recent study found that less than 25 percent of Americans use some form of lip protection. Lips are more susceptible than skin to aging from chronic sun damage and also more prone to developing serious cancers. "When skin cancer occurs on the lower lip, it has the potential to be much more aggressive and metastasize to surrounding lymph nodes," Brown said in a prepared statement. Shiny balms and glosses don't offer protection. Instead, they attract the sun's rays to the lips. "What most people don't realize is they're actually increasing light penetration through the lip surface by applying something clear and shiny to them," Brown said. (這才是重點) Women should only wear glossy lipsticks in the sun when they have a layer of sun protection on underneath, dermatologists advise. Anyone who's planning on being outdoors for more than 20 minutes at a time should use a lip sun block with an SPF of 30. Women should apply it in the morning under any lipsticks or lip glosses and then reapply the sun block throughout the day. People should check their lips for signs of cancer. Consult a dermatologist if you notice any changes to the color of the lip surface (an area turns opaque or white), or if you have persistent peeling or flaking of a spot on your lip, Brown said.(這才是重點) |

Protecting Your Lips from Skin Cancer
Tuesday September 25 - How do you protect your lips from the sun? Most women think their balms and glosses have got them covered—but experts say they're dangerously mistaken. Those can actually increase your chances of developing a skin cancer. Dr. David Winter tells us more in tonight's HealthSource report.
DR. WINTER
Wear sunscreen on your face everyday? Think you're covered? Well think again.
DR. CHRISTINE BROWN
Dermatologist
Baylor University Medical Center
"Many people do use sunscreen now however they do forget their lips."
DR. WINTER
According to a recent study, less than one-in-four Americans wear some form of lip protection. Experts say that's scary since the lips are not only more susceptible to aging from chronic sun damage—but are also more prone to developing serious cancers.
DR. CHRISTINE BROWN
"When skin cancer occurs on the lower lip it has the potential to be much more aggressive and metastasize to surrounding lymph nodes."
DR. WINTER
What's worse—many of us unknowingly attract the sun's rays to our lips by using balms and glosses.
DR. CHRISTINE BROWN
"What they don't realize is they're actually increasing light penetration through the lip surface by applying something clear and shiny to them."
DR. WINTER
In fact—dermatologists advise—women should avoid wearing glossy lipsticks in the sun altogether unless they have a layer of sun protection on underneath.
DR. CHRISTINE BROWN
"For people who are planning to be outdoors for more than 20 minutes at a time—they really should have a specific lip sun block with an SPF of 30 ideally."
DR. WINTER
So the first thing you need to do is get a lip balm or a lip sunscreen that has an SPF of 30. You should apply it in the morning under any lipsticks or lip glosses—and then reapply throughout the day just as you would a lip color. Remember, it is just as important as wearing sunscreen on your face and body.
ANCHOR TAG
What are the signs you may have developed a skin cancer on your lip?
DR. WINTER
First of all, skin cancers are more likely to appear on the lower lip. If you have any changes to the color of the lip surface—if an area turns opaque or white—or if you have persistent peeling or flaking of a spot on your lip-you should have it checked by a dermatologist.

唇蜜吸收紫外線 小心皮膚癌!(華視新聞)
擦唇蜜的女性可要注意了，美國最新研究發現，閃亮的唇蜜擦在嘴上，不僅無法保護嘴唇，反而更容易吸收紫外線，長期曝曬下，嘴唇會脫皮，還會引起皮膚癌，因此醫生建議，上妝前，嘴巴也別忘了防曬。
愛美的女性，總不忘拿起唇蜜，擠出一些抹在嘴巴上，淡淡粉紅色，讓嘴巴看起來閃亮又動人，不過小心了，美國一份研究報告指出，顏色越光亮的唇蜜，反而容易吸收紫外線， 國內 醫師也贊同這個理論。
透明的唇蜜，讓陽光光線越容易穿透，間接造成傷害，尤其長時間曝曬下，嘴唇會變得乾燥，開始脫皮。
各種顏色的唇蜜，一點也不防曬，因為容易吸收紫外線恐怕引起皮膚癌，塗抹前，記得先擦上有防曬係數的護唇膏，才不會讓愛美付出代價。(記者詹季燁、張春峰報導)
「閃亮唇蜜」 增加罹皮膚癌機率
【聯合報╱國際中心／綜合報導】 2008.04.28 02:05 am
美國達拉斯貝勒大學醫學中心皮膚科醫生克莉絲汀‧布朗指出，閃閃發亮的護唇膏和唇蜜可能吸引紫外線，增加罹患皮膚癌的風險。
每日健康新聞廿六日報導，布朗表示，保護嘴唇免於受到有害的太陽光照射，和用防曬油保護皮膚一樣重要。但最新研究發現，使用唇部保護產品的美國人還不到百分之廿五。
嘴唇比皮膚更容易因為長期陽光損害而老化，也更容易罹患嚴重癌症。布朗說：「下嘴唇罹患的皮膚癌傷害性可能更大，更可能轉移到周圍的淋巴結。」
閃亮的護唇膏和唇蜜無法保護嘴唇，反而會把太陽光吸引到唇部。布朗說：「大多數民眾不明白的是，在嘴唇上塗透明閃亮的東西，會增加穿透嘴唇表面的光線。」
皮膚學家建議，白天塗唇蜜前，應先塗一層防曬護唇膏。預計會在室外廿分鐘以上，都應使用SPF30的防曬唇膏，女性早上出門前應該把防曬護唇膏塗在任何口紅或唇蜜之下，並不時重複塗抹防曬唇膏。
布朗表示，民眾應該檢查嘴唇是否有出現任何癌症徵兆，如果發現任何表面唇色變化，例如一個區域顏色變暗或變白、或嘴唇某個部分一直脫皮，應到皮膚科就診。
***********************************************************
這裏有個很大的疑點是「護唇膏和唇蜜可能吸引紫外線」
這點在現實上實在不太可能
就像是說只要你用了護唇膏和唇蜜
紫外線就會被吸引而找到使用的部位進行破壞
這中間的邏輯不但不通而且也真的太不可思議
深入了解後發現其實”吸引-Attract”這個字並非由文中的 皮膚科 醫師所說
而是主持人在節目中問話中的一個字
而且之 後 醫師的回答並沒有提到這樣的說法
雖然主持人用Attract這個字的確有待斟酌
但在電視上為了加強民眾的注意力的確是有可能這麼說
但我想重點應該是後來 皮膚科 醫師的回答才對
原先由主持人問話中的一個字最後變 成皮膚科 醫師所說(其實是沒這樣說的)
這的確是有點被加工過的感覺
所以護唇膏和唇蜜會吸引紫外線是不對的
應該說是單獨塗上透明的唇膏或唇蜜後
因為嘴唇表面變平滑了紫外線會比較容易穿透
但倒底會增加多少的穿透量
還跟你使用唇膏或唇蜜的厚度及所照射紫外線的強度及時間長短有關
這裡所提到絕對不是全有全無的狀況
也就是說不是使用了透明的唇膏或唇蜜
就會吸引紫外線而造成唇癌(皮膚癌)
這樣子跳躍式的結論實在是很不合理的
