First: look at the price.
As the saying goes, "cheap goods are not good, good goods are not cheap", which is really suitable for pearl powder. In street stalls, we may often see some pearl powder that can be bought for 200 grams or even 300 grams for a few yuan or more. May wish to know the production cost of pearl powder: high-quality medicinal pearls are about 100 yuan/kg, plus packaging, equipment depreciation, management expenses, logistics expenses, etc. How can I buy real pearl powder at this price? Sometimes, a spendthrift may think he has found a bargain, but he has been cheated. Therefore, it is better to be wary of pearl powder with ultra-low price.
Second: look at the skin feeling.
The finer the pearl powder, the better, and of course the more expensive it is. Inferior pearl powder, the particles are very thick, and some are even as thick as sand. Might as well take a little and massage gently on the back of your hand. If you think it's rough, don't think about it. Because this pearl powder can't be absorbed by oral administration, external use will hurt the skin (especially the stratum corneum). This is a very serious matter, so it must be serious! ), it will only make you waste money.
Third: taste it.
Take a small amount of pearl powder and taste it with the tip of your tongue. Pure pearl powder has no peculiar smell, mellow taste and a faint fishy smell (or fragrance) peculiar to pearls. If it has sour taste, astringent taste, pungent taste or other peculiar smell, or has no taste, you don't have to choose it. If it tastes burnt or burnt, the powder turns yellow, which may be the residual powder of pearl diamond, and the high-speed rotation of black steel needle causes the powder to turn yellow. Long-term use of this pearl powder may lead to heavy metal accumulation poisoning.
Fourth: look at the appearance.
The appearance of fake pearl powder may be clearer than that of real pearl powder. Take a small amount of powder with your fingers, spread it out in the sun or light and observe it carefully, and you may find obvious flash. This is mica powder. If pearl powder is obviously yellow or dark, it means that the texture is impure.
Fifth: look at the fineness.
The finer the pearl powder, the better, because it is easily absorbed by the human body. After practice, I found that the fluidity of fine pearl powder is very poor. Let's give a simple example: when beans are placed on an inclined plane, they easily roll down (good fluidity), and when they are ground into bean powder, their fluidity is much worse, so they should be brushed off. Most pearl powder on the market is packaged. Try to pinch the bag when you buy it. If you pinch it, its contents will quickly get out of the way (move) and leave the place where you put pressure, then: even pearl powder is extremely thick. Real pearl powder, even if it only reaches the 200 mesh or 300 mesh specified in the Pharmacopoeia, will not be like this.
Sixth: Choose a reliable brand.
Some netizens often ask: Can you recommend some better brands and types? In fact, there are differences in raw materials and processing, such as seawater pearl powder and freshwater pearl powder, and there are also some differences in price and quality.
