In this era of "face value is justice", anti-aging and anti-wrinkle is a topic that many fairies discuss every day.

Skin care water, essence and mask have become daily necessities.

Many medical beauty projects have also become the driving force for many girls to save money.

Why at the same age, some people are younger than their peers 10 years old, while others look much older in appearance?

Do you really need to spend a lot of money or even cut your face to stay young?

In fact, it is not difficult to make you younger than your peers in the right way!

The BBC documentary "How to delay aging" tells us with super-scientific experimental basis, what can be done to delay aging?

I have to say that this documentary is simply the gospel of skin care fairies.

Many times, we can see some skin care tips and anti-aging tips.

But we never thought, why does our skin age?

This time, the BBC documentary "How to Delay Aging" tells you the answer with research.

The protagonist of this documentary is plastic surgeon Rozina.

Rozina's daily work is related to the skin. Like many friends, she wants to know the underlying causes of skin aging and then give targeted solutions to skin aging.

Rozina left his familiar operating room and went to the laboratory to study advanced dermatology. The opening of How to Delay Aging gives us an unexpected and certain conclusion: the biggest culprit of long wrinkles is sunshine.

Why are you sunburned?

The documentary tells us the answer:

The rays of the sun will destroy the collagen of our skin, and the skin will wrinkle only because the collagen begins to shrink.

Of course, defining wrinkles directly seems unconvincing.

"Speaking with facts" is the consistent theoretical style of BBC documentaries.

Rozina and scientists decided to study truck drivers who drive for a long time.

"Will there be wrinkles in the sun?" The answer is ready.

The driver was tested under the irradiation of special instruments.

Wrinkles under the detection and treatment of the instrument, the naked eye can see that the wrinkle density and depth of the driver's left and right faces are obviously different!

It stands to reason that even if there are wrinkles, there should not be much difference between the cheeks on both sides.

But why do drivers have significantly different test results on both sides of their faces?

The answer is consistent with our previous conclusion:

Due to the particularity of the working environment, one face of the driver is exposed to the sun for longer than the other face.

The driver is in the driver's seat, protected by the windshield, which directly isolates UVB into short-wave ultraviolet rays, so that the skin of the truck driver will not be sunburned because of sitting in the car.

But long-wave ultraviolet rays are everywhere, so it is not so easy for simple glass to resist.

UVA has a longer wavelength, which can penetrate glass and penetrate deep into skin, eventually weakening collagen and causing wrinkles.

Being in the sun will really get old. After reading these, I realized that the sunshine is not so good.

It can be directly concluded that whether there are wrinkles or not has a lot to do with sun protection.

Even indoors, it will be "harassed" by UVA, let alone outdoors.

So whether it's cloudy during the day or inside or outside the car, we need to apply sunscreen.

When buying sunscreen, you should not only check the sun protection coefficient, but also pay attention to the UVA rating. Five stars can prevent aging caused by sunlight to the greatest extent.

Besides sun protection, what else should we pay attention to?

We continue to explore "the secret of preventing skin aging" with Rozina.

Anyone who knows a little about skin care is familiar with the term collagen.

When describing a young man, people often say that "her face is really full of collagen".

Correspondingly, with age, the whole skin looks shriveled, which is also due to the lack of collagen.

The BBC didn't say much about collagen, but introduced us to a cell: fibroblast.

Don't underestimate this cell, it is the producer of collagen.

With it, why don't you worry about your collagen?

But fibroblasts are not as "strong" as you think.

Human beings need oxygen for survival. I'm afraid everyone knows this professional knowledge, but little known is that 1%-2% oxygen is not directly circulated by the human body, but forms free radicals.

The cumulative effect of free radicals counteracts the body's own defense mechanism.

Free radicals slowly and overwhelmingly overcome the body's defense mechanism, which will cause human aging and directly damage fibroblasts that can produce collagen.

A new discussion point is just around the corner. What can we do to repair damaged fibroblasts?

The BBC's How to Slow down Aging gives us part of the answer to the question simply and clearly: diet.

Food is the most important thing for people. What should we eat?

Can you repair fibroblasts, continuously produce collagen, and make skin youthful and energetic?

Fairy Dan? The BBC naturally won't give such a mindless answer.

The documentary "How to Delay Aging" directly takes us through what we should eat and what we shouldn't eat.

The first item is: brightly colored food. In the BBC documentary, the representative thing is tomato.

The main reason why tomatoes are brightly colored is that they contain a special ingredient: lycopene.

Lycopene can absorb oxidation, prevent oxidative stress, and have a good repair effect on fibroblasts.

The second item is: bitter vegetables. Some friends may struggle: life is bitter enough, why can't it be sweeter?

The vegetables listed by BBC here are actually not bitter, but a healthy vegetable that fitness people often include in their recipes: broccoli and carrots.

They contain an ingredient called glucosinolate, which is a natural anti-aging and antioxidant substance.

After the human body ingests this ingredient, glucosinolates will be stored in the skin, so that the skin has the ability to protect itself.

The third item is fish. By eating a large number of oily fish, we can achieve the purpose of anti-aging.

Fish contains a special substance: omega-3 fatty acids.

Some fish can even play an anti-inflammatory role, inflammation will lead to oxidative stress reaction of the skin, and the unique substances of fish can eliminate inflammation in skin cells, which is naturally beneficial to anti-aging.

The first three items are recommended foods for everyone to eat.

The fourth item is the food that people avoid: starchy foods, such as potatoes, rice and pasta.

The last study in How to Delay Aging is whether it will lead to aging.

You'll never guess: sugar.

Little fairies who like to order milk tea and eat desserts naturally have a daily sugar intake higher than the average. Free skin health and beauty test form

But BBC research shows that sugar intake also determines skin aging.

Most obviously, when diabetics guess the options and match their age through their appearance.

The conclusion is that diabetics generally look older than their peers. Later, the study directly tested the relationship between blood sugar and skin, and found that the relationship between blood sugar and appearance age was very significant.

The experiment confirmed the conclusion that people with hyperglycemia are older than those with hypoglycemia.

To this end, the protagonist of our documentary also personally tested his blood sugar.

Rozina's statistics of hundreds of researchers show that she is ten years younger than her peers.

Then the blood sugar content in her body was tested, and the result was hypoglycemia.

After reading these experimental data, I have to think that sugar is also the enemy of time.

The sugar ban movement must be put on the agenda. ...

After several major events, the documentary is also drawing to a close, and we are racing against time to make the following summary:

1, pay attention to sun protection.

2. Eat more brightly colored food, fatty fish and bitter food like broccoli.

3. Reduce the intake of starch

The most important thing is to give up sugar.
