The term "primary liquid" originated from industrial manufacturing and is used to describe the parent of concentrated liquid of industrial raw materials. After the stock solution is introduced into the cosmetics industry, it refers to a skin care product. Let me introduce it to you, I hope it will be useful to you!

What is an "inventory solution"

The so-called stock solution is a high-purity liquid that is directly extracted from pure natural plants or other raw materials and has its curative effect. It is the essence of skin care products. Originally added as an ingredient of daily beauty products, it is now taken out separately to become a high-purity single product, and the effect is greatly improved.

Effect of stock solution

The stock solution can penetrate into all levels of the panel, promote the microcirculation and metabolism of the panel through the absorption of water channels, and also play a bridge role between the panel and other skin care products. When water-soluble nutrients enter and leave the panel cells, they have special efflux, which is called "water channel". This water channel is sent to the panel by the "biological water channel protein" that constitutes the cell membrane.

Usage of skin care stock solution

The use order of stock solution is: Cleansing-Stock solution * * Full face * *-Toner-Eye cream-Cream or Emulsion-Sunscreen and BB cream are needed during the day.

Usage: The stock solution is equivalent to concentrated essence, which is water-soluble, so it must be used before toner. After using the stock solution, care the skin according to the order of using skin care products. After the stock solution, use toner, then use essence, and finally use emulsion, or add it to emulsion.

When using after cleansing, drop the stock solution between the thumb and forefinger of tiger's mouth, and use 1~2 drops or an appropriate amount each time, * * *, because tiger's mouth is one of the places with the lowest body temperature, and the higher the temperature, the fastest absorption of stock solution, so don't use the palm. If the palm temperature is high, the stock solution is easily absorbed by the palm.

Storage: the stock solution should not be placed in high temperature place, in the sun. Because it is the essence of living cell stock solution, it is best not to open the refrigerator for preservation. Remember to use it every day after opening it. It's basically 1-2 months!
