PM2.5 damage to the skin
PM2.5, which causes haze weather, is a general term for a very small particle of air, including sulfur dioxide, nitrogen oxides, sulfates, nitrates, etc., which are so small that they are undetectable, and their average size is only about It is one-twentieth of the diameter of the hair. These highly irritating environmental pollutants adhere to the skin and cause a lot of potential irritation and damage to the skin. The acidic substances such as sulfur dioxide and nitrogen oxides in PM2.5 air pollutants can stimulate the skin, and the dust floats. Particles can also clog pores and prevent normal skin detoxification and breathing. In the haze, the air contains a lot of polluted particles and microorganisms. These substances are attached to the skin and cause the metabolic cycle of the skin to be affected. The problem of sebum accumulation, blackheads and enlarged pores is more obvious. If it is easy to cause acne physique, it is easy to induce acne. Nitrogen compounds in PM2.5 also cause free radical reactions and inflammatory reactions, which damage the extracellular matrix and cell membrane, and dry the skin, produce false wrinkles, and accelerate the dark yellow and aging of the skin.
How to skin care in smog weather
1, isolation protection
The first principle to avoid skin smog damage is to create a barrier to the skin when it's out, so that it is isolated from airborne contaminants. When working outdoors, try to wear long trousers to reduce the chance of contact between the body and harmful substances in the air. Masks are the most effective essential for protecting your face. Generally, conventional masks will not work. Because PM2.5 particles are too small, KN90, KN95, and N95 dust masks can effectively filter such fine particles. At the same time, choose a mask that suits you to avoid intimacy. leakage. It is necessary to pay attention to the regular cleaning of the mask. Remove the PM2.5 filter before washing, dilute with a neutral detergent and add water, then put the mask into it, gently wash it by hand, and dry it in a cool place. Do not wash in the washing machine with other clothing. It is generally recommended to clean once every 1~2 weeks, and the filter should be replaced during cleaning.
Even if you wear a mask, your skin must not be naked. In addition to skin care steps such as water lotion, essence, and cream, we also need to use sunscreen, BB and other products to protect the skin from pollution to a certain extent. It is important to pay attention to the choice of fresh and non-sticky skin care and isolation products to reduce the adhesion of skin to PM2.5 particles.
2, deep cleaning
When you go out, you should wash your face and bare skin immediately. In fact, even extremely small PM2.5 particles cannot pass through the stratum corneum and pores of healthy skin, and air-contaminated particles generally only adhere to the skin surface. Therefore, the most effective way to combat air pollution against skin damage is to clean, and most of the particles attached to the skin surface can be washed away by cleansing products. In the choice of cleansing products, the dry and cold season should be based on mild moisturizing type. Care should be taken to avoid the use of abrasive cleansing products, which may cause damage to the skin surface. Excessive cleaning can also damage the skin's protective barrier.

After the pores of the skin are opened by warm water, gently rub the ring with your fingertips. It is recommended to use a foam-rich cleaning product to bring out facial dirt. And while cleaning the face, stay in the place where the blackheads and other blackheads are easy to generate for 10-20 seconds, and daily targeted care to avoid the residual substances in the haze.
Cleansing point3: instrument assist
A high-tech cleansing instrument that can deepen the dirt inside the pores is a good helper for deep cleansing of the skin in a smoky environment. When choosing a cleansing device, be sure to check and feel whether the brush hair is fine enough, gentle enough, and you must see a cluster of Whether the arrangement is neat and tidy, and also should choose a face brush with fast and slow gear adjustment. When using, you can use the quick gear to make foam, and the slow gear to clean, so as not to cause too much vibration frequency to cause irritation to the skin.
3, timely moisturizing
The haze weather is often accompanied by the dry climate and dust. The skin is exposed to water and dryness in this environment. Therefore, it is very important to replenish moisture in time. In addition to the moisturizing step in the morning skin care step, during the daytime When you return to the room in an outdoor smog environment, you can simply clean your face with a wet wipe and then use a spray to replenish your skin. After going home at night, you should immediately remove the makeup cleansing, and then immediately add moisture to the skin, from the moisturizing lotion to the moisturizing cream, to the refreshing moisturizing eye cream, one can not be less. If you feel that your skin is particularly dry during the day, it is better to apply a dense hydrating mask to your skin.
4, fight free radicals (antioxidation)
The nitrogen oxides in PM2.5 cause free radical reactions, and free radicals are the culprit of skin aging. Therefore, it is necessary to do anti-free radical work for the skin. In addition to regular skin care products, it is recommended to add an antioxidant product to the skin care step. The common and effective antioxidant ingredients in skin care products should look for the following: tocopherol acetate (vitamin E derivative), grape polyphenols, Coenzyme Q10, astaxanthin, etc.
In addition, the smog has a lot of free radicals after entering the human body, so when we encounter smog weather, in addition to doing a "face" project, we must also clean up the free radicals generated in the body so that we can get from inside to outside. The full protection of the skin. The only effective way to fight free radicals is to supplement antioxidants. Drinking tea and taking vitamin C and vitamin E can eliminate free radicals, because the tea polyphenols contained in tea are an antioxidant. Everyone eats vitamin E and eats vitamin C, which can strengthen and maintain the antioxidant effect of vitamin E.
Also, keep in mind these antioxidant-rich foods: mangosteen, tomatoes, grapes, red wine, salmon, nuts, broccoli, blueberries, pomegranates, lemons, spinach, green tea, cherries, and carrots.
5, repair the skin barrier
It can be found from scientific research that skin damaged by the skin barrier is more susceptible to air pollution. The causes of impaired skin barrier function are various, such as decreased skin immunity caused by decreased skin cell viability, excessive cleansing or excessive skin care, lack of sleep, dryness and lack of water, and the like. Therefore, in a heavily polluted environment, skin care should be as simple as possible, do a basic moisturizing, and choose a targeted repair product that has the function of rebuilding the skin barrier. >>>Smog days teach you how to wash your face clean
