As the cosmetics applied on delicate skin, I believe everyone is very concerned about its safety. As a result, some unimaginable and even toxic cosmetics detection methods spread on the Internet! For example, what water test emulsion method, fire burn cream method, etc., then these spread of cosmetics testing good or bad method, really useful?
In fact, many of these methods are unreliable. Most of them are derived from the "pseudoscience" of "three no wechat products" and "pyramid selling products"! It's easy for Xiaobai to believe these rumors through some fake model experiments. After all, "I saw it with my own eyes". When I saw a simple test method, I could easily believe that with the original intention of benefiting people around me, the rumor spread naturally. But seeing is not necessarily true. Cosmetics and skin care products are just like medicines. Because of their strong professionalism, it is difficult for ordinary people to fully understand. It is still up to product endorsement, national inspection and the third component analysis.
Today, let's have a good chat. Are the cosmetics detection methods circulating on the Internet really correct?
Facial Cleanser
Rumor 1: there is a light fragrance. It should be water-soluble when squeezed on the hand, and there is no greasy feeling.
Most facial cleansers are water-soluble. The main body of facial cleanser is water, accounting for about 50-80% of the total weight, and the rest is additives. If these additives are insoluble in water, the cleanser will be stratified, just as water and oil will be stratified if they are insoluble. Have you seen two layers of facial cleanser? So there is no basis to measure the quality of facial cleanser with water. Most additives of PS are soluble in water.
Myth 2: put the cleanser into the spoon and burn it with fire. If it splashes oil, it means that the cleanser is not good. If it burns more like milk, it means that the cleanser is better.
Burning and splashing oil have nothing to do with the quality of facial cleanser, which proves that the product is added with oily ingredients or emulsifiers at most. Many sensitive skin cleansers will add oil ingredients to reduce the degreasing power. The common amino acid facial cleanser will splash oil when burning, but it is safe and mild. Therefore, oil splashing can only prove that the cleaning power is not particularly strong, and the more milk is burned, the more milk is just formula technology, which has nothing to do with the quality.
Myth 3: take out the pH test paper and squeeze it directly onto the test paper, you will know
The skin of human body is weak acid. The pH value of normal skin surface is about 5-7, and that of Oriental is about 4.5-6.5. If the pH value is out of balance, the skin will become fragile, resulting in a series of skin problems.
Alkaline facial cleanser is higher than pH7. It is generally clean and suitable for oily skin and mixed skin. However, alkaline facial cleanser is not suitable for long-term use, but long-term use will stimulate the skin to secrete more oil. Facial cleanser is the best pH value for the skin, which will not hurt the skin, but also achieve the effect of skin friendly. You can't just think that the higher the better, the lower the better. The pH value that suits you is the best.
PH value < 7 is acid, pH value = 7 is neutral, pH value > 7 is alkaline
FSK amino acid facial cleanser: the golden ratio of soap based amino acids is suitable for the pH value of human body, and it does not contain mineral oil, pigment and alcohol. It is proper and gentle, and does not irritate the skin!
emollient water
Refute the rumor: after shaking, watch the bubble.
① Less bubbles means less nutrients
② There are many bubbles, but it means there is salicylic acid. Salicylic acid has a good effect on skin cleansing, but it is very irritating and allergic.
③ Many bubbles are very thin and soon disappear, indicating that they contain alcohol and are easy to damage the skin's protective film.
④ The bubbles are delicate, rich, thick and durable, that is, good water.
Whether there are bubbles after the water shakes depends on whether there are foaming ingredients in the water, while the nutrition ingredients and the foaming ingredients are two concepts, and there is no inevitable connection. The size, shape and stability of bubbles are only different in the structure of foaming components, which can not indicate good or bad. The bubble disappears quickly and slowly, except for the characteristics of the foaming agent itself, and may also be affected by defoaming components. The defoaming component causes the bubble to burst by destroying the elasticity of the bubble film, thus accelerating the bubble disappearance.
Vitamin C is not easy to froth in aqueous solution, adding a little cleansing cream or emulsion to shake bubbles in water.
Remember: nutrients have nothing to do with bubbles, vitamin C is not easy to bubble.
Batumi hyaluronic acid high moisturizing lotion: it does not contain eight additives, such as pigment, Nipagin ester, silicon, mineral oil, etc. it is not only efficient in moisturizing, but also does not hurt the skin. You can safely query the ingredients.
Cosmetics
Rumor dispelling: find a silver ornament, put on the make-up, and turn black to indicate that it contains lead and mercury.
Did you watch more costume plays? Silver needle tests poison. There are often plots in ancient costume dramas. Most of the ancient poisons were arsenic trioxide. In ancient times, the production technology was backward. It was inevitable that sulfide existed in the synthesis of arsenic. In fact, silver reacts with sulfide in arsenic. If it is replaced with enough pure arsenic, silver will not turn black.
You can insert the silver ring or chopsticks into your egg yolk. The silver ring / chopsticks will turn black too. It's just oxidized.
The blackening of silver ornaments does not mean the presence of mercury, which is just a metallic oxidation reaction. The reason for the reaction is not whether it contains mercury, but the pigment composition in cosmetics (such as iron oxide). How to test mercury in cosmetics? Please call the Health Bureau.
Yihuaye pop Twilight Lipstick: this lipstick formula uses natural petal pigment and other ingredients, with multiple effects of lasting moisturizing, filling fine lines on lips, making lips more pure and transparent.
Cleansing Water
Rumor: pour some makeup remover on lipstick and mascara on the back of your hand to see if it's easy to blend with make-up and wipe away with tissues.
In addition to the makeup removing ability, the makeup removing products should not be prickly and hot when they are used on the face. If they are only tested on the hand, they will mistakenly think that the products with strong cleaning power are good makeup removing products.
Therefore, the ingredients of cosmetics are not good or bad when you dissolve them with water or burn them with fire, but when you understand the ingredients list.
Green tea warm moisturizing makeup remover: skin friendly vegetable oil formula, no mineral oil and other irritant ingredients, gentle makeup remover without residue, can be used for eye and lip makeup remover.
Facial mask
Rumor: using a money detector or ultraviolet lamp to mask the mask. If fluorescence occurs, a fluorescent agent will be added, which will cause cancer and produce dependence.
It is unscientific to detect directly with ultraviolet radiation. Ultraviolet radiation can show fluorescence reaction, and the substances with fluorescence reaction are not necessarily fluorescent agents. There are many substances in nature have fluorescence reactions, such as plant flavonoids, most vitamins and so on. This is a natural reaction, not a fluorescent agent.
And whether the fluorescent agent can cause cancer has not been determined by the scientific community.
Mei an zhe Xi Xiu Xiu series mask: No fragrance, alcohol, artificial colors, preservatives and mineral oil! Affinity does not hurt the skin! Deeply replenish the water, quickly repair the damaged skin, and help you find the golden age beauty!

Xiaose is still that sentence, Professional people do professional things. Cosmetics is a highly professional industry. It is difficult for ordinary people to fully understand. Instead of believing in these pseudoscience, it is better to exercise their eyes and select qualified products and public praise products that meet the national testing regulations. Of course, you can also avoid unsafe ingredients through the third-party cosmetics ingredient testing website.
