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.

覆盖在嘴唇上的精细皮肤层特别容易干燥和破裂。根据Rapid City医疗中心的说法，虽然身体的其他部位含有能够自我水合的油腺，但我们的嘴唇却没有，这使得我们很容易因缺水而嘴唇皲裂。润唇膏的目的是通过使用乳木果油或凡士林等保湿成分来防止这种痛苦的干燥。唇膏还含有蜡，它是一种粘合剂，可以使唇膏牢固地贴在嘴唇上。

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，又称唇裂，通常是由环境因素引起的，如过度暴露在阳光下或过敏原，以及炎热或寒冷的天气变化。嘴唇皲裂会影响成人和儿童，并会因频繁用舌头舔嘴唇而变得更糟。

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.

因为嘴唇皲裂会很痛苦，所以润唇膏似乎是解决问题的合理方法，但某些润唇膏可能会使问题变得越来越严重。

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

虽然润唇膏是用来滋润嘴唇的，但产品中的水分最终会蒸发，进而嘴唇更加干燥。

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，皮肤科医生Melissa Piliang解释说，润唇膏中的某些成分可能比保湿成分更具脱水性，他说，“含有苯酚、薄荷脑和水杨酸等成分的润唇膏实际上会让你的嘴唇更干燥”。从而导致反复使用唇膏，杜兰大学皮肤病学助理教授Leah Jacob博士将其描述为“恶性循环”

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).

不仅如此，含有香味添加剂的润唇膏也可能造成额外的伤害，博士特别提到了薄荷口味。这些种类的香味或调味成分可能导致过敏患者进一步干燥，甚至引发过敏反应。

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.

选择含有预防性保湿成分的润唇膏将有助于保持嘴唇充分水分，缓解不适。克利夫兰诊所的专家建议选择由凡士林制成的唇膏，以及SPF为30或更高的产品，以帮助保护嘴唇免受阳光照射。选择含有这些成分的唇膏将有助于防止嘴唇持续皲裂。
