Most of the masks sold in the market now contain preservatives, because the mask makeup essence is covered on the mask paper, which is easy to cause bacterial pollution. Long-term storage requires adding a certain dose of preservatives to 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 masks containing preservatives for a long time, which is easy to further aggravate the allergic phenomenon for some people with particularly sensitive skin.
Applying the mask to the face will provide lasting penetration, because it takes a long time to apply the mask, and because of the high permeability of the mask itself, if there are preservatives, the cumulative use of preservatives will penetrate deep into the skin, which will easily cause skin allergies and injuries. Healthy skin is balanced, but improper use of mask will destroy this balance of skin. If there is a mask that works very well after being used several times, you must be careful. This mask often contains prohibited ingredients.
In another case, the mask was fine when it was first used, but it felt uncomfortable after using it for a while, so you should pay attention at this time. If the mask itself is a compliant product, it is necessary to consider whether it is an additive, such as preservative, essence, activator, etc. We can't see the harm of side effects in a short time. After long-term cumulative use, it is likely to cause skin allergies, red blood and so on. Therefore, sensitive skin should avoid using masks containing additives and preservatives.
In daily life, there are many patients who seek medical treatment because of skin allergy, and the situation of allergic inflammation caused by mask is on the rise. What should I do if I encounter such an allergic problem? First, stop using it. The simplest and safest way at home is to keep cold compress. Soak a towel or thick gauze in cold mineral water and keep it on your face for more than 10 minutes. If the cold compress effect is not obvious the next day, it is recommended to go to the hospital in time. However, it should be noted that some people are allergic to blisters and cannot use cold compress at this time.
Facing the dazzling array of mask products on the market, consumers should be careful not to blindly follow suit. Choosing products such as masks is not as expensive as possible, but varies from person to person. The most important thing is to suit yourself. Some people have sensitive skin. When choosing a mask, avoid additives such as preservatives, essences and active ingredients. Women who often use masks should also avoid using masks containing preservatives.
Mask dressing is the first choice for many women who love beauty. Various products emerge in an endless stream on the market, with functions ranging from initial moisturizing to acne removal, whitening and lifting. But can you really wear a mask? Does a small mask really have so many "magical" effects?
What should I pay attention to before applying the mask?
Remove makeup, no makeup, and apply sunscreen. You can gently wipe your face with a cotton pad with mild makeup remover or cleansing oil when your face and hands are dry. Sensitive skin can be wet-applied with mild makeup remover for 5-8 minutes, then emulsified and washed with water.
Choose mild cleansing products, such as amino acids, hyaluronic acid, glycerin, etc., gently massage the whole face for 2~3 minutes, and finally wash and dry with water.
It should be reminded that the temperature of washing water should not be too high and the cleaning intensity should not be too high. It is recommended to use a good quality cleansing towel or cotton pad to dry your face. Ordinary towels are hard when used for a long time, which is easy to breed bacteria and make facial skin more sensitive.
What are the misunderstandings of applying mask?
Myth 1: The mask can replenish water for a long time.
"Mask is a kind of skin care products with different functions and different formulas, which can be divided into moisturizing type, whitening type, acne removing type, cleaning type and anti-wrinkle type." Zhong, a dermatologist at Peking University Hospital, took moisturizing mask as an example, saying that its moisturizing components such as hyaluronic acid, hyaluronic acid and collagen are mainly water quality, which can temporarily increase the moisture content of stratum corneum. Other types of facial masks will add some auxiliary materials, such as sorbitol, squalane, glycerol, 1-3 propylene glycol, etc., so they also have a certain moisturizing effect. However, none of these ingredients can reach the deep layer of the skin. When the cuticle is dry and atrophied or sebum secretion is insufficient to lock water, water will be easily lost and the skin will be dry, so there is no long-term effect.
Myth 2: you can't laugh when you apply a mask, otherwise it will wrinkle.
When some beauty bloggers send tutorials, they often teach everyone to lie flat when applying masks. There should be no major changes in the face, such as not laughing, otherwise wrinkles will easily grow. But is this really the case?
Zhong said that it is "totally unreasonable" to say that you can't laugh or that you will have wrinkles. "Wrinkles are a problem with the deep structure of the skin. Long wrinkles are a cumulative process, which is related to many factors such as time, skin aging and expression. The mask can only work in the stratum corneum. Although it has an effect on relieving dry fine lines of epidermis, it will not affect the deep structure of skin. Therefore, in the process of applying the mask, it is very unlikely that laughter will directly lead to long wrinkles. "
Myth 3: It is better to apply a mask every day.
In order to maintain a good skin condition, beauty bloggers tirelessly advocate applying more masks, and many stars seem to apply masks every day. But is it really necessary to apply a mask every day?
Zhong believes that masks generally do not need to be applied every day, and the frequency of use is not absolute. It depends on the composition, skin quality and purpose of applying masks.
If it is acute skin inflammation, the mask plays a role in convergence, and you can do cold compress for a period of time every day; If it is used to replenish water, it can be applied every other day, or it can be used at any time when needed; Daily use of cleansing mask will cause skin sensitivity and even redness, so it can be used once a week; Moisturizing mask is easy to grow acne when used every day. It is recommended to use it once or twice a week.
Dr. Laila recently wrote that the outermost layer of skin has stratum corneum, and in a healthy state, 10%-30% is water. There is also a sebum membrane outside the stratum corneum, which has a certain moisturizing and water-locking function under normal circumstances. "Long-term abnormal moisture content of the skin will gradually destroy the skin barrier." Zhong stressed that it is not necessarily a good thing to apply a mask to the skin every day.
Myth 4: mask = culture medium, and applying mask breeds bacteria.
It is widely rumored on the Internet that applying a mask is equivalent to applying a culture medium to the face, and nutrients will not only be absorbed but also breed bacteria. Zhong was very surprised by this. "This statement is a bit too unscientific. Mask and culture medium are completely different. It is purely a rumor that the mask is breeding bacteria. "
The most common facial mask on the market is a water-based facial mask consisting of facial mask paste, facial mask base cloth and essence. Culture medium refers to the nutrients artificially cultivated in the laboratory for the growth and maintenance of microorganisms, plants and animal cells or tissues, and its main components are carbohydrates and nitrogen-containing substances. "Masks are not a culture medium for bacteria. Masks produced by regular manufacturers have been tested and disinfected before leaving the factory, and human facial skin is a resistant, healthy and complete barrier. Simply put, masks and faces themselves do not meet the conditions for bacterial growth. It is even more sensational and nonsense to breed bacteria on the face after applying the mask. "
Masks and these pits, avoid them!
Yang Xichuan, chief physician of dermatology department of the First Affiliated Hospital of Chongqing Third Military Medical University: Many women have a soft spot for facial mask skin care, and these facial mask pits should be avoided.
Direct application of fresh fruits and vegetables should be careful of allergies.
In the small coup of online transmission, it is often advocated to apply fresh fruits and vegetables directly to the face, which is actually a misunderstanding! Some fruits and vegetables do contain vitamin C, but the content is very small, and it is not 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 lemon, strawberry and pineapple. Lemon is very sour and acid is corrosive; Strawberry and pineapple are rich in acidic components such as tannic acid and fruit acid, which will exfoliate. People with sensitive skin can't stick it directly on the skin, otherwise it will cause great irritation to the skin, and it is prone to symptoms such as facial dryness and redness. In severe cases, it will cause skin allergies.
Strong whitening mask beware of fluorescent agent.
The function of fluorescent whitening agent in cosmetics is mainly to brighten the skin. This ingredient can be added not only to facial mask, but also to other whitening creams. There is no effect on facial skin in a short time, and they will look "much whiter than before" when deposited on the skin. But it is not as easy to decompose as ordinary chemical components, and it is very difficult to remove! Because it's hard to wash off and metabolize. Long-term use has security risks!
Quick freckle mask, be careful of hormones.
Although the country has banned the use of hormones in cosmetics for a long time, it can't prevent black-hearted manufacturers from using hormones in another way, because only by adding hormones can this magical effect of quickly removing spots and whitening appear, and it can also reduce the stimulating reaction of hydroquinone and retinoic acid, or add some ingredients that can interfere with hormone detection. If the mask containing hormones is used for a long time, it will make the skin thinner, appear red blood, have more pores, reduce the skin barrier function, make the skin prone to inflammation, and even produce hormone dependence.
How to choose and use facial mask?
Faced with various beauty "traps", how should consumers choose and use masks?
Yan Yan, director of the Department of Dermatology, Plastic Surgery Hospital of China Academy of Medical Sciences, said that the main components of most masks are water, humectants, thickeners, preservatives and functional components. Water is the solvent of facial mask, with the largest content, and it is the main source of hydration. Because the humectant contains hydroxyl groups, it can capture moisture and play a certain moisturizing role; Thickener can adjust the viscosity of the mask; Products with water must have preservatives, and masks are easy to breed bacteria, so anti-corrosion requirements are high; Active ingredients are the "main force" of skin care, such as plant essence, marine life, etc., and also the key to determine the efficacy of the whole mask. Yan Yan believes that ordinary hydrating masks, or conceptual masks such as red wine, silk and bird's nest, although they have skin care effects, have limited effects and lack scientific basis, and cannot be infinitely exaggerated. In addition, the effect of the mask depends on whether the manufacturer extracts effective substances and adds antioxidants to maintain its activity, which is difficult for consumers to judge from the outer packaging.
Li Liqun, deputy director of Medical Aesthetics and Beauty Branch of Zhejiang Medical Association, president of Scar Plastic Surgery Branch of Zhejiang Plastic Surgery Industry Association and director of plastic surgery department of the First Affiliated Hospital of Wenzhou Medical University, pointed out that medical masks are produced aseptically, including clean workshops and sterilized raw materials, which can be directly applied to skin wounds, while ordinary skin care products have no such strict requirements in all aspects of production. Therefore, when choosing a mask, if it is necessary for skin treatment, you should go to a medical institution and choose a medical mask according to the doctor's advice. If it is for your own skin care, the mask produced by regular manufacturers is still relatively safe. Don't choose the "three noes" products sold by various small channels.
"At present, the ingredients in the mask are very messy. However, the formula of medical mask has been simplified without adding non-functional additives. Not only the raw materials have been strictly screened, but also the safety and effectiveness of the products have been tested and clinically verified, and the mechanism of action is more clear. The simple summary is: the composition is clear and targeted. " Li Liqun said that there are many kinds of other non-medical masks, which can be divided into cleaning, moisturizing, repairing, whitening, wrinkle removal and anti-aging. Consumers should choose according to their skin conditions and needs.
In addition, we must also recognize the words "makeup" and "machinery". Those marked with "make-up" and "machinery" are all regular products that meet national standards, while those marked with "eliminated" are not suitable for face use. At the same time, I suggest you go to regular shopping malls to buy, and don't trust WeChat merchants and informal overseas purchasing. Choose a mask to recognize your skin condition, and choose a mask with thin essence for oily skin; Dry skin should be based on essence and thick texture.
The application time is also particular. The flaky mask can't be torn off after it is completely dry, but it can be taken off when the mask is still slightly wet, massaged on the face to absorb the residual essence, and then carried out subsequent maintenance. Generally speaking, the number of mask applications is not as many as possible. It is recommended to apply it 2 ~ 3 times a week in spring, autumn and winter, and once every two weeks when the air humidity is high in summer.
