● Is your skin aging prematurely?
In addition to endogenous cell aging, the most important factor in human skin aging is exogenous aging. Among these exogenous factors, sun exposure is the first factor causing skin aging, commonly known as "photoaging" by doctors. In order to slow down skin aging, many young and middle-aged people are paying more and more attention to daily sun protection.
Have you chosen the right sunscreen?
Midsummer has arrived. Facing the scorching sun, have you chosen and used the right sunscreen? In this episode of " I am a great doctor ", the program team specially selected the 7 sunscreens with the highest purchase rate and conducted real-person tests under the scorching sun. What kind of sunscreen is more effective? The
program team used white tape to separate 10 4*5cm squares on the backs of the staff. Except for the top grid, which is not applied as a control group, the remaining 9 grids are evenly coated with equal amounts of sunscreen of different brands. Stay exposed to the sun for 2 hours outdoors, observe the progress of the experiment every half hour, and ask the subjects how they feel. Finally, based on the sun protection results, a sunscreen with better sun protection effect can be summarized.
"I Am a Doctor" invited Wang Baoxi, Secretary of the Party Committee and Chief Physician of the Department of Dermatology of the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences, to analyze the experimental results at the recording site. The test results show that sunscreens with higher SPF values are relatively more effective, and sunscreens that combine physical and chemical combinations also stand out among the seven sunscreens.
Experts remind that if your skin is sensitive, you should try to choose alcohol-free sunscreen. At the same time, three common ingredients in sunscreens are hormones or preservatives. In order to reduce the contact between skin and preservatives, you should try to choose benzophenone-3, hydroxyphenyl propyl ester , methyl isopropyl ester, etc. in the ingredient list. For sunscreens containing thiazolidinone ingredients, the simplest way is to choose a sunscreen with a relatively short shelf life, which also contains relatively few preservatives.
Which sun protection clothing is more effective?
Sun protection clothing is also a common item for people to protect themselves from the sun in summer, especially among young girls. However, with all kinds of sun protection clothing on the market, which one can provide effective sun protection? "I Am a Great Doctor" conducted a simple experiment on site, and people can also refer to this method when choosing sun protection clothing.
In addition to preparing various sun protection clothing , the program team also prepared a UV flashlight and a hundred-yuan bill. Use an ultraviolet flashlight to shine a hundred-dollar bill through the sun-protective clothing. If the anti-counterfeiting mark on the banknote is clearly visible, it proves that the sun-protective clothing may not have the ability to block ultraviolet rays. The less obvious the anti-counterfeiting mark is, the stronger the ability of the sun protection clothing to withstand ultraviolet rays.
Washing your face like this may make your face look bad!
Experts said that many people in daily life "don't know how to wash their faces." The so-called "not knowing how to wash your face" does not mean that you cannot wash your face cleanly, but it means that you have washed your face too much. The outermost layer of human skin is a layer of sebum film , which is an important barrier to protect skin health. Many people feel that their faces are oily in summer, so they wash their faces too frequently or too seriously. Some beauty-loving women wash their faces for up to half an hour at a time. As everyone knows, such excessive cleaning may have damaged the skin barrier, eventually making " sensitive skin " more and more common.
To master the real method of washing your face, experts gave the "Three Ones for correct face washing" formula - "Only use facial cleanser once a day, use 1 soybean-sized amount of facial cleanser, and scrub for 1 minute." This will not only keep your face clean Leaves skin refreshed without excessive damage to the skin barrier.
In addition to summer skin care, there are many detail minefields. How should we avoid them in life? Tonight at 21:00, we will summarize the "Summer Skin Strategy" with Beijing Satellite TV's "I Am a Great Doctor"!
