After the emulsion is opened, it will come into contact with the air, which will lead to the oxidation or deterioration of the effective components, plus dust and other problems, which will deteriorate for too long.
The shelf life of Shiseido Toner in Japan is three to five years.
Article 6 1 of Japan's Pharmaceutical Affairs Law stipulates that only "products that will deteriorate within 3 years under normal storage conditions" must be marked with the shelf life. If it is not marked, it means that the shelf life of the product in unopened state is at least 3 years.
If Shiseido's skin care products can't be sold within 2 years, they will all be cleared, and basically all the products are sold within the shelf life.
