Why can the cosmetics be stored in room temperature and do not spoil without preservatives?
A3. We cannot explain in detail since it is one of our trade secrets. What we can say is that we use an antibacterial ingredient from plants to make cosmetics that can be stored for three years, if not opened, and safe for two months after opening without “preservatives.” In addition, there are some moisturizers that are effective in suppressing the propagation of unwanted bacteria, also. We positively use those to successfully produce the cosmetics that do not spoil without preservatives.
