越用唇膏嘴唇越干!

The fine layers of skin covering our lips are particularly susceptible to dryness and breakage. According to Rapid City Medical Center, while other areas of the body contain oil glands to self-hydrate, our lips do not, leaving us vulnerable to chapped lips due to water loss. The purpose of lip balm is to prevent this painful dryness from occurring through the use of hydrating ingredients such as shea butter or petroleum jelly (via WebMD). Additional ingredients include wax, which serves as an adhesive to keep the balm firmly in place on our lips.

覆蓋在嘴唇上的精細(xì)皮膚層特別容易干燥和破裂。根據(jù)Rapid City醫(yī)療中心的說法，雖然身體的其他部位含有能夠自我水合的油腺，但我們的嘴唇卻沒有，這使得我們很容易因缺水而嘴唇皸裂。潤唇膏的目的是通過使用乳木果油或凡士林等保濕成分來防止這種痛苦的干燥。唇膏還含有蠟，它是一種粘合劑，可以使唇膏牢固地貼在嘴唇上。

Cheilitis, otherwise known as chapped lips, most often develops as a result of environmental factors such as excessive sun exposure or allergens, as well as hot or cold weather changes (via Cleveland Clinic). Chapped lips can affect both adults and children and can be exacerbated by frequent licking of the lips with one's tongue.

唇炎，又稱唇裂，通常是由環(huán)境因素引起的，如過度暴露在陽光下或過敏原，以及炎熱或寒冷的天氣變化。嘴唇皸裂會(huì)影響成人和兒童，并會(huì)因頻繁用舌頭舔嘴唇而變得更糟。

Because chapped lips can be painful, lip balm seems like a logical solution to the problem, but certain lip balms may be making the problem go from bad to worse.

因?yàn)樽齑桨椓褧?huì)很痛苦，所以潤唇膏似乎是解決問題的合理方法，但某些潤唇膏可能會(huì)使問題變得越來越嚴(yán)重。

Although lip balms are intended to hydrate the lips, the moisture from the product eventually evaporates, further drying out our lips (via Live Science).

雖然潤唇膏是用來滋潤嘴唇的，但產(chǎn)品中的水分最終會(huì)蒸發(fā)，進(jìn)而嘴唇更加干燥。

Additionally, dermatologist Melissa Piliang explains that certain ingredients in lip balm can be more dehydrating than they are hydrating, stating, "Lip balms containing ingredients like phenol, menthol and salicylic acid actually make your lips drier" (via Cleveland Clinic). This can lead to repeated product application, which assistant professor of dermatology at Tulane University Dr. Leah Jacob describes to Live Science as "a vicious cycle."

此外，皮膚科醫(yī)生Melissa Piliang解釋說，潤唇膏中的某些成分可能比保濕成分更具脫水性，他說，“含有苯酚、薄荷腦和水楊酸等成分的潤唇膏實(shí)際上會(huì)讓你的嘴唇更干燥”。從而導(dǎo)致反復(fù)使用唇膏，杜蘭大學(xué)皮膚病學(xué)助理教授Leah Jacob博士將其描述為“惡性循環(huán)”

Not only that, but lip balms with scented additives can be additionally damaging, with Dr. Jacob citing peppermint flavors in particular. These kinds of scented or flavored ingredients can contribute to further dryness or even prompt allergic reactions in those with allergies (via Cleveland Clinic).

不僅如此，含有香味添加劑的潤唇膏也可能造成額外的傷害，博士特別提到了薄荷口味。這些種類的香味或調(diào)味成分可能導(dǎo)致過敏患者進(jìn)一步干燥，甚至引發(fā)過敏反應(yīng)。

Choosing a lip balm with preventative moisturizing ingredients will help keep lips adequately hydrated and relieved of discomfort. Experts at the Cleveland Clinic suggest choosing lip balms made with petroleum jelly, as well as products containing an SPF of 30 or more to help keep lips protected from sun exposure. Choosing lip balms with these ingredients will be helpful in preventing ongoing chapped lips.

選擇含有預(yù)防性保濕成分的潤唇膏將有助于保持嘴唇充分水分，緩解不適?？死蛱m診所的專家建議選擇由凡士林制成的唇膏，以及SPF為30或更高的產(chǎn)品，以幫助保護(hù)嘴唇免受陽光照射。選擇含有這些成分的唇膏將有助于防止嘴唇持續(xù)皸裂。
