A paper on Maillard reaction
The most difficult skin care problem I have ever encountered is that my friend with sensitive muscles asked me:

"How do our sensitive muscles fight aging?"

Although I know the answer, I really can't bear to tell ta, because it is really too difficult for sensitive muscles to resist aging. Not only should we improve redness caused by sensitivity, fine lines caused by dryness, fine lines caused by cell damage and photoaging, not to mention sagging, relaxation and wrinkles caused by age.

The most important thing is to buy skin care products for sensitive muscles, which is super easy to "explode" and easily stings and blushes. If you buy it wrong, it is a few months' repair period. Tired! Sensitive muscles are not anti-aging, but they must be cautious. When they are anti-aging, they must also be repaired so that they are not easy to roll over.

Why is it easy to sting with various efficacy products, peeling for three days and rotten face for five days? Because the skin barrier of sensitive muscles is too poor.

The season-changing stage is a sensitive period of high incidence. Frequent changes in temperature and long-term exposure will bring irritation to the skin. Death behaviors such as excessive cleaning and excessive mask application can also destroy the skin barrier. Coupled with young people staying up late for a long time, work pressure and other factors, it is easy to trigger the sensitive state of the skin and reduce the skin's tolerance to the external environment.

The damaged skin barrier is like a broken wall. Other houses are well defended, and you have a big hole here. Compared with healthy skin, fragile skin barrier is more likely to accelerate cell damage and aging.

Common allergens such as pollen and dust, as well as common pollutants such as PM2.5 and PM 10, are like soldiers who attack the city wall. They are attached to the skin wall and constantly stimulate the skin to produce proinflammatory factors such as interleukin, TNF-α [1][2], so that sensitive muscles are in a state of "high stress response" for a long time.

These irritants will trigger a chain reaction of the skin, just like a string of firecrackers, and lighting one is a series of explosions. TRPV 1 receptors on sensitive skin are easily activated, which causes the skin's own immune and inflammatory reactions [3] and leads to telangiectasia; The activity of related protease on skin increases, which leads to the aggravation and destruction of skin barrier [1]. In the end, it will produce a series of stress reactions, causing damage to its own cells, aggravating skin aging, and making the aging problem of sensitive muscles come faster.

Fragile sensitive muscles should pay more attention to anti-aging and repair than healthy skin, improve skin tolerance, improve skin microenvironment, reduce the release of proinflammatory factors and minimize cell damage.

One of the main causes of skin aging is ultraviolet rays. Ultraviolet (UVA) can directly penetrate cells and damage DNA. Short-wave ultraviolet (UVB) can cause skin thermal pain and other reactions, and produce pro-inflammatory factors. Sensitive muscles are in a state of "high stress response", and the activity of TRPV 1 related receptors is higher than that of normal skin [1][3]. The thermal effect brought by ultraviolet rays is more obvious, so it is easier to be damaged by ultraviolet rays, resulting in stress oxidation and photoaging of skin.

What we commonly call the antioxidant process is the process of neutralizing free radicals and interrupting skin damage. However, many functional ingredients that can be used by ordinary skin are unbearable for sensitive muscles. For example, the prototype VC with high concentration has excellent antioxidant effect, but in order to ensure the activity of components, the product formula with low pH value must be used, which greatly improves the irritation. Sensitive muscles will sting when touched, which is more likely to aggravate sensitive problems.

In addition to anti-oxidation, glycosylation problems that occur in ordinary skin can also occur in sensitive muscles. Although the cake is delicious, sugar is also the old enemy of skin care products. Glucose produced by decomposition will combine with collagen in skin, resulting in Maillard reaction and brown substance. "300 lychees a day" of the imperial concubine, certainly not less efforts in skin care.

Look at the bright red braised pork, which is the help of "frying sugar" The products of Maillard reaction will not only lead to dull and uneven skin color, but also make collagen brittle and inelastic, and the skin will not look so tender. So if you don't want to add some "sugar color" to your skin, you must do a good job of anti-saccharification.

Sensitive muscles are anti-aging, anti-oxidation and anti-saccharification, so they must be gentle and safe, and can't add stimulation to the skin barrier with low lipid!

Speaking of this, we must introduce the protagonist of Amway this time, Winona, a skin care brand under Bettignies Group, which focuses on sensitive muscle care.

Winona was born in Yunnan. Relying on superior geographical environment and rich products, Winona cooperated with many experts in the field of dermatology in China to develop a series of skin care formulas focusing on plant active essence. Focus on improving common sensitive skin problems and repairing skin barriers.

Winona Laboratories has developed many skin care products for sensitive muscles by using the green thorn fruit from Bajia Snow Mountain in Shangri-La. Not only the product production follows GMPC standard, but also has clinical cooperation with dozens of hospitals in China, and has published many domestic dermatological papers on eczema and atopic dermatitis.

Yesterday, Winona and five dermatological industry associations held the second sensitive skin summit forum. At the meeting, Winona released new breakthroughs and new progress in the field of anti-aging of sensitive muscles, and launched the first anti-aging essence specially developed for sensitive muscles-Shuangxiu Shuangkang Essence.

Double repair can also double anti-aging and give sensitive muscles a safe, gentle and effective skin care choice.

Double repair, temporary and permanent.

One of the main components in this essence is "Cercidia utilis oil ceramide".

Sensitive muscles should be familiar with ceramide, which is an essential lipid in skin barrier, accounting for about 50% of intercellular substance, and is an important raw material for repairing sensitive muscles.

The thorn fruit contains about 40% oily substances, which can promote the expression of ASH 1 enzyme related to ceramide and promote the skin to synthesize ceramide itself. Moreover, the fatty acid content of the green thorn fruit is close to the skin lipid, which can supplement essential fatty acids for the skin, moisturize and instantly improve the problem of dryness and tightness [6].

Winona Shuangxiu Shuangkang Essence is a component of Nitraria oil ceramide, which is a combination of Nitraria oil and sphingosine, the precursor of ceramide. It can not only promote the production of ceramide, but also directly supplement ceramide needed by skin barrier. This is the repair of the essence of double culture and double antibody, which fundamentally improves the tolerance of skin barrier.

The second cultivation is the sour pulp and purslane extract in the essence of Shuangxiu Shuangkang.

Physalis alkekengi calyx contains a lot of flavonoids and saponins, which can neutralize free radicals, regulate skin microenvironment, resist oxidation and improve sensitivity.

Portulaca oleracea extract is an essential ingredient for skin care of sensitive muscles. Studies have found that Portulaca oleracea extract can reduce the release of inflammatory factors, stabilize skin hyperresponsiveness and improve sensitive problems.

Using Portulaca oleracea and Physalis alkekengi extracts to inhibit inflammatory factors, relieve the sensitive state of skin and reduce the damage of free radicals to skin, which is the second repair function.

Double anti-aging, collagen regeneration, full skin elasticity.

In the aspect of anti-aging, double-cultivation and double-resistance essence is also a strategy to choose hands. Firstly, the components extracted from Yunnan Pu 'er tea were used. Tea polyphenols, EGCG and other components contained in tea not only have excellent antioxidant effect, neutralize free radicals of skin itself, reduce cell damage, but also prevent photoaging damage to skin caused by UVB [9].

In addition, Gastrodia elata extract [10] and myopeptide can promote the production of collagen and inhibit the activity of metalloproteinases that decompose collagen. It is also a good anti-saccharification ingredient, which can reduce skin saccharification and make skin color more uniform.

Light and not greasy, light and moist.

The barrier of sensitive muscles is not perfect, so most moisturizing products will pay special attention to moisturizing, moisturizing and supplementing sebum. But in the face of this rising temperature, no matter how dry the skin is, you can't paste the cream willfully.

The texture of double-repair and double-reverse essence is clear and not greasy, very silky, which can bring light moisturizing effect and will not be greasy at all. When applied to the face, it is light coagulation, which is very easy to absorb.

It can be used alone in spring and summer, and cream can be superimposed in autumn and winter, and it is versatile and does not rub mud, and it is free from sun protection.

Whether you have dry skin, oily sensitive muscles, or dry sensitive muscles, double-repairing double antibody essence must be very suitable for you. Cercidia utilis oil ceramide repairs skin barrier and supplements essential lipids; Physalis alkekengi and Portulaca oleracea extract can repair skin microenvironment, reduce inflammatory factors and improve skin tolerance; Yunnan Pu 'er tea extract can resist oxidation and improve aging. Gastrodia elata root extract and carnosine can resist saccharification, promote collagen production and cooperate with anti-aging.

Double repair, double anti-aging, all aspects are considered for sensitive muscles, new products are on the market, don't miss it!
