2. Don't easily believe that there are quick-acting whitening products with hot-selling advertisements on the market. At present, there are many whitening products on the market, and some of them can see the whitening effect as soon as they are painted. But do you dare to use such a product? In fact, there is no product that can really whiten quickly and is safe and reliable. These products with instant whitening effect can be divided into two categories:
One is to add reflective and fluorescent ingredients, such as mica, so that when people apply it to their faces, their skin will refract more light and look white. In fact, mica gives the skin a false whitening effect. However, if this mineral powder is used for a long time, if the cleansing and makeup removal are not thorough, it is easy to block pores and cause inflammation and acne.
Another quick-acting whitening product is to add hormones, steroids and so on. It can achieve rapid whitening effect in a short time, and these substances may cause hormone-dependent dermatitis and make the skin unhealthy if used for a long time; It may also be absorbed by the skin and enter the blood, endangering our overall health. Therefore, it is best not to buy or use such quick-acting whitening products.
3. Don't wash your skin too frequently. Some people love to talk about hygiene and pay attention to the cleaning industry. They always think that they are dirty after going out, and they have to take a long bath after going home to be comfortable, so that their skin becomes defatted and dry, and even dermatitis, eczema and decreased resistance appear all over the body. Even buying expensive skin care products to repair it won't help. After years of research, now everyone has a common sense that the natural sebum film on the human body surface is very important, and it is easy to destroy its natural state and balance state if it is washed frequently.
4. Never wash your face with cleansing wipes instead of washing your face! Nowadays, many girls wipe their faces with wet tissues instead of washing their faces. There are many brands of cleansing wipes on the market, but try not to use them on your face, especially those marked with sterilization and disinfection function. These wet wipes often contain alcohol, preservatives and other raw materials, which are irritating and easy to aggravate the formation of acne and acne. In windy and dusty weather, if you just wipe your face with a wet paper towel, it is more likely that dirt will remain in the pores of your skin and scratch your skin, so don't wash your face with a cleansing paper towel instead of water.
5. Never use skin care products for skin test. No matter what brand, function and dosage form of skin care products, you must buy small packages before you decide to use them, and conduct a local skin test on the inner side of your arm for 1 month to observe whether the skin has any adverse reactions such as redness, itching and acne. Adverse reactions caused by skin care products often cannot occur in a short time and need long-term observation, preferably one month. Therefore, you must do a skin test before changing skin care products.
