面霜，可防止与年龄相关的皮肤病
“Anti-aging:” In thebeauty world, it’s a term used on face creams that claim to reduce wrinkles and increase brightness. But new research shows that the right skin-care routine may slash your risk of chronic disease as you age, too.
As it turns out, skin — the largest organ in the body — may be at the root of the low-level inflammation that occurs throughout the body as we get older, according to a small new study, out of the University of California at San Francisco (UCSF) and the San Francisco Veterans Administration Health Care System. The good news? Using a moisturizing cream all over your body could lower that inflammation and lower your risk of certain diseases.
衰老相关的炎症（“充气衰老”）与疾病有关Alzheimer’s disease,diabetes, andcardiovascular disease. While scientists formerly believed the liver or the immune system was to blame for this inflamm-aging, the UCSF study points toward the skin instead.
“炎症必须来自足够大的器官，以至于非常轻微的炎症会影响整个身体。皮肤是一个很好的候选人，因为它的规模，“学习高级作者毛强人，M.D.是一位新闻发布的高原皮肤科研究科学家M.D。“一旦我们变老了，我们的皮肤病症状就像瘙痒，干燥，酸度的变化。可能是皮肤具有非常轻微的炎症，因为它是如此的大器官，它升高了循环细胞因子水平。“这意味着甚至很少的问题都可以转化为整个身体的炎症，因此增加了某些疾病的风险。
The team that worked on the study, published in theJournal of The European Academy of Dermatology and Venereology, used a skin cream, which was developed based on the researchers’ previous work, to reverse age-related skin damage. A group of 33 adults between ages 58 and 95 used the cream, which contained three types of lipids that promote skin health and moisture — cholesterol, free fatty acids, and ceramides — all over their bodies twice a day for a month. When the month was over, the UCSF scientists measured the participants’ blood levels for three cytokines (a type of protein) that have been linked to age-related inflammatory diseases.
结果显示,成年人使用的皮肤cream had lower levels of the three cytokines after the month was over, and their levels were also lower than those of adults who had not used the skin cream. In fact, the older adults who used the cream ended up with cytokine levels as low as the levels of people in their 30s.
In addition to reducing inflammation, the skin cream lowered pH, improved skin hydration, and repaired the permeability barrier. And that barrier is key — when broken, it can cause inflammatory signals to be released into the blood.
“[In a larger study]随着人们年龄将阻止那些下游疾病的发展，我们将看到是否使用奶油将表皮功能保持正常。“如果我们这样做，这一含义就是在50岁之后，您希望在您的余生中每天申请有效的题单屏障修复准备。”
Until then, skin moisturizers do a face and body good for other reasons too (a.k.a., softness, smoothness). These products contain the three key lipids from the study (but note that they may not be at the exact ratio specified in the study): SkinCeuticals Triple Lipid Restore 2:4:2($128, DermStore), Ceramedx Ultra Moisturizing Cream ($17.99, ceramedx.com), and CeraVe Daily Moisturizing Lotion ($10.49, Amazon).
根据美国皮肤科学院的说法，这些其他提示可以帮助您保护您的皮肤并防止干燥：
Apply a moisturizer right after your bath or shower; it’ll soak in best on damp skin.
If you have parched skin, go for ointments and creams over lotions for more intense moisturization.
And don’t forget sunscreen: Research shows that using one with an SPF of 30 or more can protect your skin better than a lower SPF, even if you don’t apply it properly.
