Hello, I am happy to answer this question. Facial masks are very effective skin care products, but because facial mask paper is the best breeding ground for bacteria, the facial mask paper contains nutritional essence and also provides a good breeding ground for bacteria. Therefore, facial masks need to add a lot of preservatives to curb bacterial interference. What effects will the preservatives in facial masks have on the skin? How to avoid skin damage caused by preservatives?
Most of the facial masks currently sold on the market contain preservatives. Because the essence of facial mask cosmetics is covered on the mask paper, it is easier to cause bacterial contamination. A certain amount of preservatives needs to be added for long-term storage. Make the shelf life longer and more conducive to sales. ”
But it is precisely because of the addition of preservatives that if used improperly, it will cause other skin problems. Preservatives are a very common and important cause of allergies. Many women use products containing them for a long time. Masks containing preservatives can easily aggravate allergies for some people with particularly sensitive skin.
Applying the mask on the face will provide a continuous penetration effect, because the time it takes to apply the mask will increase. It is relatively long, and due to the high permeability of the mask itself, if there are preservatives, the cumulative use of preservatives will penetrate into the deep layers of the skin, which can easily cause allergies and damage to the skin. Healthy skin has a balance, but improper use of the mask will cause it. If there is a kind of facial mask that is particularly effective after just a few uses, you must be careful because it often contains prohibited ingredients.
Another situation is that the mask is still there when it is just used. Okay, if you feel uncomfortable on your skin after using it for a while, you should also pay attention at this time. If the mask itself is a compliant product, you must consider whether it is an issue with additives, such as preservatives, flavors, activators, etc. Short Time cannot tell the damage of side effects. After long-term cumulative use, it is likely to cause skin allergies, redness, etc., so people with sensitive skin should avoid using masks containing additives and preservatives.
In daily life, many patients seek medical treatment for skin allergies, and allergies and inflammation caused by facial masks are on the rise. If you encounter such allergies, what should you do first? The easiest and safest way to do it at home is to apply continuous cold compress. Soak a towel or thicker gauze with cold mineral water and apply it on the face continuously for more than 10 minutes. If the cold compress is not effective the next day, it is recommended to go to the hospital in time. . But it should be noted that some people are allergic and may develop blisters, and cold compresses cannot be used at this time.
In the face of the dazzling array of facial mask products on the market, consumers should be careful not to blindly follow the trend and choose. The more expensive the mask and other products, the better. They vary from person to person. The most important thing is that they should be suitable for you. Some people have sensitive skin. When choosing a facial mask, you should avoid using additives such as preservatives, fragrances, and active agents. Women who frequently wear facial masks should also avoid using facial masks that contain preservatives.
Facial masks are the first choice for skin care for many beauty-loving women. There are various products on the market, ranging from hydrating to moisturizing. Acne removal, whitening, tightening, everything. But do you really know how to apply a facial mask? Does a small facial mask really have so many "miraculous" effects?
What to do before applying a facial mask? What should you pay attention to?
To remove makeup, even if you are wearing sunscreen, you can use a mild makeup remover or makeup remover and wipe it gently with a cotton pad while your face and hands are dry. Face. For those with sensitive skin, apply mild makeup remover for 5 to 8 minutes, then emulsify and wash off with water.
Use a mild cleanser, such as one containing amino acids, hyaluronic acid, and glycerin. Use cleansing products, gently massage the entire face for 2 to 3 minutes, and finally rinse with water and pat dry.
It should be reminded that the temperature of the face wash water should not be too high and the cleaning power should not be too strong. It is recommended to use a cleansing towel or a good-quality cotton pad to dry your face. Ordinary towels will become hard after being used for a long time and are prone to breed bacteria, making facial skin more sensitive.
What are the misunderstandings about applying facial masks?
Myth 1: Applying a facial mask can provide long-lasting hydration
“Face mask is a kind of skin care product with different functions and formulas, which can be divided into moisturizing, whitening, acne removal, and cleansing care. and anti-wrinkle types.
"Zhong Shaomin, a dermatologist at Peking University Hospital, takes moisturizing facial masks as an example. Its moisturizing ingredients such as hyaluronic acid, hyaluronic acid, and collagen are mainly water-based and can temporarily increase the moisture content of the stratum corneum. Other types of facial masks will add appropriate amounts. Excipients, such as sorbitol, squalane, glycerin, 1-3 propylene glycol and other substances, therefore also have a certain moisturizing effect. However, these ingredients cannot reach the deep layers of the skin. When the stratum corneum is dry and shrunken or the sebum secretion is insufficient to lock in moisture, Moisture will be lost easily and the skin will be dry, so there will be no long-term effect.
Myth 2: Don’t smile while wearing a mask, otherwise you will develop wrinkles.
Some beauty bloggers post tutorials. At that time, everyone was often taught to lie flat when applying a facial mask, and not to make any major changes to the face, such as not smiling, otherwise wrinkles would easily occur. However, is this really the case?
Zhong Shaomin said that when applying a facial mask, It is "completely unreasonable" to say that you can't smile otherwise you will develop wrinkles. "Wrinkles are a problem of deep skin structure. Wrinkles are a cumulative process and are related to many factors such as time, skin aging, and expression. The facial mask can only work on the stratum corneum. Although it is effective in alleviating dry fine lines on the epidermis, it will not affect the deep structure of the skin. Therefore, the possibility of wrinkles directly caused by laughing during the application of the mask is very small. ”
Misunderstanding 3: Facial masks must be applied every day for better results
In order to maintain good skin condition, beauty bloggers tirelessly advocate applying more facial masks, and many celebrities seem to do so every day Wear a facial mask. But is it really necessary to apply a facial mask every day?
Zhong Shaomin believes that facial masks generally do not need to be applied every day, and the frequency of use is not absolute, depending on the ingredients of the mask, the type of skin and the application of the mask.
If it is an acute skin inflammation, the mask can be used as a cold compress every day for a period of time; if it is used to replenish water, it can be applied every other day or used at any time when needed; the cleansing mask can be used every day. It can cause skin sensitivity and even redness and swelling, so you can use it once a week; using a moisturizing mask every day can easily cause acne, so it is recommended to use it once or twice a week.
Dr. Clove recently pointed out that the outermost layer of the skin has. The stratum corneum, in a healthy state, is composed of 10% to 30% water. There is also a sebum film outside the stratum corneum, which under normal circumstances has a certain function of moisturizing and locking water. "The skin will gradually increase in abnormal moisture content for a long time. Damage the skin barrier. "Zhong Shaomin emphasized that wearing a facial mask every day without any skin problems is not necessarily a good thing.
Misunderstanding 4: Facial mask = culture medium, wearing a facial mask breeds bacteria
There are rumors on the Internet that wearing a facial mask Zhong Shaomin was very surprised by this, saying, "This is a bit unscientific. Masks and culture media are completely different things. Applying a mask can breed bacteria." Pure rumors. ”
The most common facial mask on the market is a water-based mask composed of mask stickers, mask base cloth and essence. The culture medium refers to the laboratory for the growth and growth of microorganisms, plants and animal cells or tissues. The main ingredients of artificial cultivation nutrients are carbohydrates, nitrogen-containing substances, etc. "Face masks are not a culture medium for the growth of bacteria. Masks produced by regular manufacturers are tested and sterilized before leaving the factory, and human facial skin is a sterile environment. To put it simply, neither the mask nor the human face itself meets the conditions for the growth of bacteria. It is even more sensational and nonsense that bacteria will breed on the face after applying the mask. ”
There are pitfalls in applying facial masks, avoid them!
Yang Xichuan, Chief Physician of the Department of Dermatology, First Affiliated Hospital of Chongqing Third Military Medical University: Many women have a soft spot for facial masks for skin care. , you should learn to avoid these mask pitfalls
Be careful of allergies when applying fresh fruits and vegetables directly
Online tips often advocate using fresh fruits and vegetables to apply directly on the face. This is actually a misunderstanding! Some fruits and vegetables. It does contain vitamin C, but the content is very small. It cannot be absorbed much when applied to the face. In addition, fruits and vegetables also contain other ingredients, which will not only hinder the absorption of vitamin C, but also easily cause allergies, especially irritating fruits and vegetables, such as lemons. , strawberries, pineapples, etc. Lemons are very acidic, and acids are corrosive; strawberries and pineapples are rich in tannic acid, fruit acid and other acidic ingredients, which will have an exfoliating effect. People with sensitive skin cannot apply them directly. On the skin, otherwise it will cause great irritation to the skin, prone to dryness, redness and other symptoms, and in severe cases, skin allergies.
Be careful with fluorescent agents in powerful whitening masks
The main role of fluorescent whitening agents in cosmetics is to brighten the skin. This ingredient can not only be added to facial masks, but can also be placed in other whitening creams. If used in a short period of time, it will have no effect on facial skin. When they are deposited on the skin, it will look "much whiter than before." But it is not as easy to be broken down as ordinary chemical components. It is very difficult to remove it! Because it is difficult to wash off and metabolize. There are potential safety hazards in long-term use!
Be careful with hormones in quick freckle removal masks
Although the country has long banned the use of hormones in cosmetics, it still cannot stop unscrupulous manufacturers from using hormones in different ways, because Only by adding hormones can this magical effect of rapid freckle removal and whitening occur. It can also reduce the irritating reaction of hydroquinone and retinoic acid, or add some ingredients that can interfere with hormone detection. If you use a mask with hormones for a long time, your skin will become thinner, red bloodshot, pores will appear, the skin barrier function will decrease, the skin will become prone to inflammation, and you may even become hormone dependent.
How to choose and use facial mask?
Faced with various beauty “traps”, how should consumers choose and use facial masks?
Yan Yan, director of the Department of Dermatology at the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences, said that the main ingredients of most facial masks include water, moisturizers, thickeners, preservatives, functional ingredients, etc. Water is the solvent of facial masks, with the largest content, and is the main source of hydration; moisturizers can have a certain moisturizing effect because they contain hydroxyl groups that can capture water; thickeners can adjust the viscosity of facial masks; products containing water Preservatives are a must. Facial masks can easily breed bacteria, so the preservative requirements are high. Functional ingredients are the "main force" of skin care, such as plant extracts, marine organisms, etc., and are also the key to determining the efficacy of the entire facial mask. Yan Yan believes that although ordinary hydrating masks, or concept masks such as red wine, silk, and bird's nest masks, have skin care effects, their effects are limited and lack scientific basis, so they cannot be exaggerated indefinitely. In addition, the effectiveness of the mask depends on whether the manufacturer has extracted effective substances and added antioxidants to maintain activity, which are difficult for consumers to judge from the outer packaging.
Li Liqun, vice chairman of the Medical Aesthetics and Cosmetology Branch of the Zhejiang Medical Association, president of the Scar Plastic Surgery Branch of the Zhejiang Plastic Surgery and Beauty Industry Association, and director of the Plastic Surgery Department of the First Affiliated Hospital of Wenzhou Medical University, pointed out that medical facial masks are made of non-woven fabrics. Bacterial production, including purified production workshops and sterilized raw materials, can be directly used on skin wounds, while common daily skin care products do not have such strict requirements in all aspects of production. Therefore, when choosing a facial mask, if you need skin treatment, you should go to a medical institution and follow the doctor's instructions to choose a medical mask. If you use it for daily skin care, facial masks produced by regular large manufacturers are relatively safe. Do not choose the "three noes" products sold through various small channels.
"At present, the ingredients contained in facial masks are very complicated. However, the formula of medical facial masks is streamlined and does not add any non-functional additives. Not only the raw materials have been strictly screened, but the safety and effectiveness of the products have also been tested Tests and clinical verification have shown that the mechanism of action is clearer, and a simple summary is: clear ingredients and strong targeting. "Li Liqun said that there are many types of other non-medical facial masks, and their functions can be roughly divided into cleaning, moisturizing, repairing, whitening, and wrinkle removal. Anti-aging, etc., consumers should choose according to their skin conditions and needs.
In addition, you must also recognize the word "makeup" and the word "machine". Products marked with the font size "Zhuang" and "Mechanical" are regular products that meet national standards, while those marked with the font size "Xiao" are not suitable for use on the face. At the same time, it is recommended that everyone go to regular shopping malls to buy, and do not trust WeChat merchants and informal overseas purchasing agents. When choosing a facial mask, you need to understand your skin condition. Oily skin types should choose masks with thinner essences; dry skin should choose masks with thicker essences.
The time of application is also important. The sheet mask cannot be peeled off after it dries completely. You can remove it when the mask is still slightly moist, massage your face to allow the remaining essence to be absorbed, and then perform follow-up care. Generally speaking, the more frequently you apply a facial mask, the better. It is recommended to apply it 2 to 3 times a week in spring, autumn and winter. In summer, when the air humidity is high, once every two weeks is enough.
