Will pearl powder turn black when used during the day?
Pearl powder is not sensitive, hehe ~MM, your worry is a bit redundant. Pearl powder+emulsion is a good combination, especially suitable for dry skin, which can moisturize, lock water and whiten skin ~ and make skin more delicate and safe to use ~ it will only get whiter and whiter if it doesn't turn black.
4 strokes to identify the authenticity of pearl powder
smell
Real pearl powder will smell a little salty, while fake pearl powder often has no taste.
look
The real pearl powder is not pure white, but a little gray, which will be more obvious on white paper. Fake pearl powder is often pure white.
bubble
Real pearl powder will produce many bubbles when it comes into contact with white vinegar. Calcium carbonate in pearl powder will react with acid to produce a large amount of carbon dioxide gas. Moreover, if vinegar is put before pearl powder, pearl powder will not sink immediately, but will float on the surface first, and then the upper and lower particles will gradually separate and sink.
There are two kinds of fake pearl powder on the market, one is totally fake, the other is doped, and the latter accounts for a large proportion. When these two kinds of pearl powder are poured into vinegar, some of them often sink first, and a large number of bubbles cannot be produced.
burn
The above three methods can only identify whether there is real pearl powder, but can't judge the purity of pearl powder. Burning method can judge the authenticity and purity of pearl powder by observing the burnt pearl powder.
Real pearl powder will turn grayish yellow after burning, while fake pearl or pearl powder with low purity will have black powdery impurities.
Principle of pearl powder in treating skin spots
In the theory of traditional Chinese medicine, chloasma, freckles and pigmentation are closely related to yin-yang imbalance and qi-blood disharmony, while western medicine believes that these symptoms are related to endocrine imbalance. However, both Chinese and western medicine believe that local patches should be treated by adjusting the whole body state, and should not be limited to the treatment of local patches like most cosmetics.
How long does the pearl powder mask last?
15-20 minutes.
Like many other masks, it is enough to make pearl powder mask 15-20 minutes at a time. The raw material of pearl powder mask is pearl powder, and the powdered pearl powder becomes sticky because of adding liquid substances. However, this pearl powder will gradually dry when it comes into contact with air, and when the mask is dry, it will absorb the moisture in the skin in reverse. Therefore, it is recommended to apply 15-20 minutes.
