Introduction of pearl powder beauty knowledge

1. 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.

2. One of the methods of western medicine to treat chloasma, freckles and pigmented spots is to treat with vitamin C, which has the reputation of beauty vitamin. This is mainly because vitamin C can prevent the formation and precipitation of melanin. However, the limitation of treating these skin diseases with vitamin C is still great, because the appearance of facial plaques is often a sign of abnormal lesions in the body. It is not suitable for most patients to treat pigmentation simply by inhibiting melanin precipitation, nor is it a radical solution.

3. Traditional Chinese medicine emphasizes the root cause. Compendium of Materia Medica has long recognized that pearls are a good medicine for treating skin spots. It is recorded in the book: pearls, except noodles. Dull is a general term for chloasma and other skin patches in traditional Chinese medicine.

4. Modern medical research shows that the excellent curative effect of pearl powder on facial spots is achieved through systemic regulation.

Processing method of pearl powder

Pearl powder is made from pearls. Pearl powder was prepared by traditional water-flying method in China Pharmacopoeia and Chinese traditional medicine processing standard. Due to the increasing market demand of pearl powder, the traditional process has low production efficiency, long production cycle and high loss rate, and microbial pollution is difficult to control. To this end, many new pearl powder processing technologies have appeared in various places. Firstly, several processing methods of pearl powder are introduced as follows:

1, traditional crushing method

Wash pearls, wrap them in gauze, add tofu (1: 1) and boil them in water for 2 hours. Take out the tofu, wash it, dry it in the sun, grind it fine, and fly it into fine powder with cold boiled water. Take it out, put it in a bamboo basket covered with paper, dry it or dry it in the sun, and then grind it fine.

2, mechanical crushing method

After washing pearls, scrub them with alkaline water to remove oil stains, rinse them with clear water to remove alkalinity, drain them or wipe them with gauze, spread them evenly on a plate, and then bake them in a constant temperature oven at 120- 160℃. When the pearl surface is yellow and cracked, cut off the power supply. When it is cooled to 60-70℃, take it out quickly, crush it with a pulverizer while it is hot, then put it in an oven for heating, grinding and sieving.

3. Ball milling method

Crushing pearls into particles and soaking them in alkaline water. Wash away oil stains and attachments, rinse with clear water until neutral, and drain. Put into a ball mill, adding appropriate amount of distilled water, and ball milling. Take it out, put it in a square pot, spread it evenly, and put it in an electric heating thermostat at 140- 160℃ to dry. Take out, cooling, and sieve in a closed vibrating screen.

4, airflow crushing method

Pearl powder which has been crushed to nearly 200 meshes is put into a jet mill and collected by a grading collection device. The powder that does not meet the requirements can continue to be crushed repeatedly until it reaches the specified fineness range.

5, vibration stirring grinding method

Soak pearls in alkaline water, rinse them to neutrality, dry them, sterilize them, and crush them in a vibrating mixer. According to the fineness requirements, different crushing media are pre-selected and crushed to the required fineness by using its vibration conditioning principle.
