1, pearl powder identification
Real pearl powder has several important characteristics, please keep in mind and pay attention to the distinction:
1. Smell. The real pearl powder has a faint taste, which is the natural taste of pearls, not the disgusting kind; Generally speaking, the smell of superfine pearl powder will be heavier than that of ordinary pearl powder; The smell of nano pearl powder is heavier than that of ultra-fine pearl powder.
2. Taste. Real pearl powder tastes slightly salty, while nano pearl powder is a bit like sugar-free milk. The taste is mellow and comfortable, and most of the shell powder is a little astringent. Inferior pearl powder has sour, astringent, pungent or other peculiar smell, or no taste. If the powder smells burnt or burnt, and the color of the powder turns yellow, it may be the residual powder of the pearl diamond, and the yellowing of the powder is caused by the high-speed rotation and heating of the black steel needle. Long-term use of this pearl powder may lead to heavy metal accumulation poisoning.
3. color. The real pearl powder color is white-like, that is, close to white. The colors of pearl powder from different processes will be somewhat different, some are slightly gray and some are slightly yellow, but they are definitely not that pale color or brown, and should be very soft;
4. price. Basically, no real pearl powder is sold in bags of100g, 200g or even 400g. A few dollars a bag, the real pearl powder is not so cheap; The production cost of high-quality pearl powder: high-quality medicinal pearl is about 100 yuan /kg, plus packaging, equipment depreciation, management expenses, logistics expenses, etc. Therefore, high-quality medicinal pearl powder must be greater than 100 yuan. Of course, it doesn't mean that pearl powder above 100 yuan is of high quality.
5. Liquidity. Fake pearl powder is made by roughly crushing shells. It's thick and heavy to hold in your hand. Looking under the lamp, you can find the flash, which is very fluid (pearl powder fine enough will become a piece when pinched and spread like sand). Identification method: Pearl powder on the market is mostly bagged. Try to pinch the bag when you buy it. If the powder quickly gets out of the way (flows) and stays away from the place where you put pressure, then even pearl powder is extremely thick. If the parts you press are not so easy to spread out, or even will not spread out, but gather into a tight ball, it means that this pearl powder is very fine.
6. Relevant certificates. Pharmaceutical pearl powder manufacturers with the quasi-brand name of National Medicine should pass GMP certification, otherwise the safety of products cannot be guaranteed. Manufacturers of high-quality pearl powder will pay great attention to every detail of their products, such as packaging, Chinese and English characters and even punctuation marks. The requirements for printing quality and packaging quality are very strict, the color will not be black, overprinting will not be inaccurate, and sealing will not be incorrect.
There are some popular folk methods to identify the authenticity of pearl powder, which are not reliable, including:
1. Add vinegar to pearl powder to see if it bubbles. Clarification: No matter pearl powder, shell powder and right powder, bubbles will appear if vinegar is added, so it is impossible to distinguish the authenticity of pearl powder by this method. If you are interested in further studying the reasons, you can refer to junior high school physics;
2. Smoke the pearl powder black with fire. Clarification: Both shell powder and pearl powder contain a certain amount of organic matter, which will turn black at high temperature. Therefore, this method can not be used to distinguish between true and false pearl powder.
3. Put it into the water and observe the sinking speed. The sinking speed is related to the surface tension of liquid, the hydrophilicity and density of powder surface, and also to the humidity of powder. In this test, it is basically impossible to judge what factors affect the sinking speed, so it cannot be used as a basis for judgment.
abstract
Fake pearl powder:
Texture: take a small amount of powder with your fingers, spread it out in the sun or light and observe it carefully. You can find a clear flash. This is mica.
Color: obviously whiter than pure pearl powder. This fake pearl powder is mixed with hydrolyzed animal protein powder, and mica will stick to the stomach after long-term use.
High quality pure pearl powder:
Texture: the powder is white, uniform in color and free of impurities.
Handle: It feels delicate and smooth, and is easily absorbed by the skin.
Smell: It smells slightly fishy, but there is no other peculiar smell.
Inferior pearl powder:
Texture: The main raw material of this powder is the powder drilled during pearl jewelry processing, mixed with talcum powder.
Color: yellowish, mainly caused by high temperature and high heat during drilling.
Smell: The smell is burnt or smelly. Black steel needle fragments fall into powder and contain a large number of metal bodies, which will make people chronically poisoned after long-term use.
2. The harm of fake pearl powder
Pearl powder is a traditional beauty product, which is deeply loved by China's ancient concubines and foreign celebrities. It is a sacred product for maintenance and restoration!
The effective components in pearl powder, such as amino acids, can regulate and maintain the whole body skin, promote the synthesis of new cells, make the skin smooth, delicate and elastic, and delay aging; It can also regulate endocrine, soothe the nerves and eliminate tension and fatigue! For this reason, in today's developed science and technology industry, pearl powder, as an ancient beauty product, has changed from a luxurious palace beauty secret recipe to a fashionable MM skin care treasure after years of baptism.
In recent years, with nano pearl powder becoming the mainstream of pearl powder market, there are too many counterfeit "nano pearl powder" in the market, which is very popular!
A sin: blocking pores and expanding pores.
Many JM think that pearl powder for oral use should be selected, and it doesn't matter for external use! So when I chose pearl powder for external use, I bought a little cheaper pearl powder with poor quality. Who knows that after using it, it has no effect and skin care is not beautiful? To make matters worse, it will damage and destroy the skin!
I hereby seriously warn all sisters: Don't be greedy for petty gain and neglect quality! Choose a good brand and quality pearl powder for internal and external use! In fact, pearl powder for external use should be thinner and better. The skin's absorption capacity is extremely weak, and the finer the pearl powder for external use, the better it will be absorbed, so it is the best choice to use good nano pearl powder. In addition, the use of fine pearl powder can avoid damage to the stratum corneum. Real pearl powder is so demanding, let alone fake. Therefore, pearl powder for external use should not be sloppy at all.
Two sins: scratching the skin and hurting pores.
Among all kinds of fake pearl powder, because the raw material is not 100% pearl, the fineness is not fine enough, and the finished product is often rough! The identification method is simple. You can see many bright spots in the light. If possible, you can look at it under a microscope and find many sharp water chestnuts. Smells tasteless, dry powder is coated on the back of the hand, and there is a tingling sensation of particles. When massaging the skin with this kind of thing, it is very easy to wear the skin. After using this pearl powder for a period of time, the skin will be very red and thin, and some will even cause irreversible allergic reactions to the skin, and even cause pores to be injured and inflamed, resulting in rougher skin.
I would like to remind you that many pearl powders on the market now can only be boiled in medicine because of their simple equipment, fineness of about 200-800 meshes, coarse particles and sharp edges. Due to the limited grinding environment, bacteria and other pollution are inevitable. JMS does not recommend skin external use! (The introduction of this fineness unit will be discussed below. Let me mention that the nano pearl powder is above 15000 mesh, and the fineness of Yongweitang reaches 15000-770000 mesh. )
Three sins: bacteria exceeding the standard and powder being polluted.
After being deceived by fake and shoddy products, Miaomiao found out about pearl powder on the Internet! In order to ensure the quality and hygiene of pearl powder, the whole process of pearl powder regeneration must be produced according to GMP standards. In particular, nano pearl powder needs to be tested in all aspects of production to ensure the aseptic, natural and organic characteristics of nano pearl powder. Now many enterprises are misleading consumers under the banner of "production according to GMP workshop" and "production according to GMP standards", but in fact, manufacturers simply do not have GMP certificates and conditions issued by the state! This fake pearl powder is easy to be contaminated by bacteria in the production process, which leads to the spread of bacteria. This fake pearl powder is harmful to human body, and it is easy to cause skin allergy and intestinal diseases, because pearl powder is generally used for a long time. This kind of harm may not be obvious at first, but it can be imagined over time!
Four deadly sins: chemical residue, poisoning human body.
In modern society, with the development of science and technology, pearl powder has also produced many preparation methods. From the most primitive mashing and grinding to the later ball milling and airflow crushing. Up to now, one of the most advanced nano-preparation technologies is chemical preparation. Chemical preparation technology uses a large number of chemicals to participate in the manufacturing process of pearl powder. This not only destroys the natural and organic nature of pearl powder, but also leaves chemical components easily, among which sodium hydroxide is the most harmful to human body. Sodium hydroxide, commonly known as caustic soda, is used by some fake pearl powder as the raw material for the initial processing of shells. It has strong irritation and corrosiveness and is harmful to human skin, stomach and respiratory tract. External use is obvious, which will cause problems such as rough skin, increased dandruff and large pores.
At present, there are not a few pearl powders made by chemical methods. At present, the national invention patent of "preparation method of all-natural nano pearl powder" is unique to only one enterprise in Zhejiang. This preparation method has high technical content, advanced equipment and high cost. Relatively speaking, chemical method is simple and low-cost, and it has become the first choice for many fake pearl powders.
Five sins: insufficient effective ingredients, pearl powder discount.
Pearl powder is a traditional beauty product in China. It is found that pearls are rich in 15 amino acids, more than 30 trace elements, B vitamins and biological calcium. These substances have a unique proportion and cannot be obtained artificially so far.
The fake pearl powder does not have the proper ingredients of these pearl powders, especially the chemical preparation technology completely changes the properties of pearl powder, and chemical solvents take away or destroy amino acids, trace elements and vitamins. Not to mention those who use talcum powder and shell powder to fake pearl powder. Tell my sisters with my own "history of blood and tears": it is impossible to obtain the beauty and health care effect brought by the magical ingredients of pearl powder with this fake and shoddy pearl powder! Oral administration is equivalent to taking calcium supplements at most; External use, the effect may not be as good as using flour as a mask.
Six sins: the fineness is not enough and it is not easy to absorb.
Many sisters don't know how to distinguish the quality of pearl powder, so I take this opportunity to give you a suggestion: Pearl contains all kinds of life elements necessary for human body. Only by grinding pearl powder into as fine powder as possible and ionizing it to the greatest extent can these life elements be fully absorbed by human body and play their special functions. For thousands of years, people have been trying to improve the processing technology of pearl powder to improve the processing fineness of pearl powder. China's pearl powder nanotechnology was successfully developed in 2003, and its fineness has reached 40~ 100 nm. The best pearl powder is of course prepared by nanotechnology and physical methods!
On the other hand, the fake and shoddy pearl powder in the market is simple in technology and backward in technology, relying on low-priced and fancy promotion methods, and its fineness can't reach the nanometer level at all. Generally, the absorption of pearl ingredients by oral administration of this fake pearl powder is only 5%- 16% of that of real nano pearl powder! In industry terms, pearl powder "goes through the intestines", no matter how cheap it is, it is also a waste! Moreover, the fineness of pearl powder is not enough, which will increase the burden on the stomach and thus damage our stomach.
But not afraid! At present, we have the independent patent of "Preparation method of all-natural nano pearl powder" in China. If you are interested, you can find JMS on China Patent Network!
Seven deadly sins: causing other potential diseases
100% pearl powder is made of pearls, which has a certain cost. Pearls are not cheap, especially medicinal pearls. Fake and shoddy pearl powder can't be made from pure pearls. Shell powder is the most commonly used, and even fake pearl powder is made directly from talcum powder and calcium carbonate (these are mostly used to make some low-priced masks). Some "smart" counterfeiters will mix some shell powder and talcum powder into real pearl powder.
This raw material can easily lead to potential diseases of human body, such as talcum powder may cause constipation (pearl powder was originally used to treat constipation, hehe, this is also an irony of a counterfeit product), and taking it in large quantities may cause female reproductive system problems and so on. Sodium hydroxide can cause gastrointestinal diseases, skin diseases, respiratory diseases and so on. Pearl powder with excessive bacteria may also cause gastric wall adhesion and intestinal infection; Using the waste powder drilled from pearl ornaments as pearl powder (this powder has a faint burnt smell, which is caused by friction and heat generated by high-speed drilling with a metal drill, rather than the normal fresh smell of pearl powder) will do harm to heavy metals accumulated in the body or skin. Once heavy metals accumulate in the skin, it is difficult to excrete them, which will bring lifelong harm.
Suggestion: When consumers buy pearl powder, they must look for regular and professional pearl powder manufacturers and brands. Don't be confused by low-priced and cheap goods, learn more and compare more. After all, pearl powder must be used well and effectively. The best way is to ask to try on a formal suit before buying!
Step 3 choose a hydrating mask
(1) In fact, there are many hydrating masks at present, and all kinds of masks confuse everyone. If you want to choose the hydrating mask correctly, you can choose according to the thickness of the hydrating mask. Because the thicker the mask proves, the more materials will be used in the mask, and the hydrating essence contained in the mask will be relatively more. We can buy one and go home, then open the package and try it on ourselves. We can put the mask flat on our hands and feel its weight. If it feels lighter, it proves thinner. We should not continue to choose this hydrating mask.
(2) In addition, it can be selected according to the consistency of the essence contained in the hydrating mask. Friends who often use hydrating mask should know that the efficacy of hydrating mask depends largely on the hydrating essence contained in the mask. Generally, those masks with good hydration will have a higher consistency. When we open the package, we will find that most of the essence is adsorbed on the mask. On the contrary, the mask essence with poor quality will be sparse and contain relatively few nutrients.
