Goggles distinguishes inferior cosmetics

Women's nature is beautiful, so all kinds of cosmetics become the "golden" weapon of the manufacturers. However, the beauty and skin care products on the market today are all called pure natural, pure plants, and do not contain any harmful substances. In fact, many of them are toxic products that are safe or have excessive chemical content. How can I buy it with confidence and use it with peace of mind? In fact, you can use a very simple method, although it can not be said to be 100% accurate, but at least it can be distinguished.

Silver ring to measure lead content

Every time Miss Li goes to the counter to buy cosmetics, she always wears a silver ring on her hand. Apply a cosmetic to the back of the hand or the root of the ear before applying it. These two parts are the most sensitive areas of the human body. After evenly applying, the silver ring on the hand (other silver products can also be replaced) is slightly rubbed in the application area. If it is black or has a light black mark, it indicates that it contains heavy metals such as lead. The deeper the black, the larger the lead content. This method is very useful in detecting hair dyes and lipsticks. Chronic lead poisoning can cause anemia, can damage people's liver, kidney, bones, cause neurasthenia, constipation, loss of appetite, etc., and seriously endanger human health.

Clear water test lotion

In the autumn and summer seasons, many people use lotions instead of creams, but the emulsion often contains a small amount of oil ester, which is easy to clog pores, causing dry and dehydrated skin, and the pores will gradually become larger over time. Emulsifiers are also included in the emulsion. Emulsifiers are surfactants that damage the skin's structure, cause skin sensitivity, and are highly carcinogenic.

To test whether these two kinds of harmful substances are contained, Ms. Liu's method is very simple: a cup of water is OK. She first poured the appropriate lotion into the water, such as the emulsion floating on the water, proof that it contains oil stone ester. Shake it gently and the liquid becomes milky white, indicating that the emulsion contains an emulsifier.

Iodine wine anti-oxidation function

Iron will rust when exposed to the air for a long time, and the peeled potatoes will turn yellow in a while, which is the result of oxidation by air. Skin is no exception. Therefore, anti-oxidation is anti-aging, and many products are also emphasizing their antioxidant function.

The secret of Yingying is to test with iodine. First, pour some water into the transparent glassware, and add iodine in the water. The ratio of iodine to water is about 1:50. Shake well and put the products to be tested, such as toner and facial cleanser, a little. Stir well. If the product and liquid are fully dissolved and the water is clear and transparent, it means it has anti-oxidation function; if the water can not be reduced or blackened, it proves that the skin will continue to be oxidized by air, which will seriously increase oxidation. .

pH test paper wash facial milk

The skin of the human body is weakly acidic. There is a weak acid film on the surface of the skin. If it is destroyed, the skin will become weak and the bacteria will grow in an alkaline environment. Therefore, the use of a weak acid facial cleanser is very helpful for cleansing the skin.

Fashionista Xiaoyan prepared some pH test strips in her bag. When she bought facial cleanser or cleansing products, she took out the pH test paper. She applied a small amount of product to the test paper first. If the test paper turned dark green after a few minutes, it indicates that the product has too much alkaline component and should not be used.
