Cosmetic preservation method
2021-06-19

Whether in use or unopened, cosmetics should be placed at room temperature, dry and inaccessible to direct sunlight; if you want to put them in the refrigerator to increase the coolness due to summer, they should also be kept away from the freezer and put them back immediately after use In original place, avoid deterioration caused by large temperature difference between in and out.


Products that are easily contaminated, such as mascara, are in direct contact with the eyelashes and are stored in the mascara bottle. It is best to replace them every three to four months.


In addition to fragrances and colorants, various high-end cosmetics also contain fatty acids, fatty alcohols, and petroleum jelly, as well as protein, lipid compounds, various amino acids, vitamins, etc.; pharmaceutical cosmetics also include royal jelly, white fungus, pearls, and ginseng And other organic matter. The above organic substances are not only beneficial to the skin, but the preservatives in the cosmetics are sufficient to inhibit or kill harmful microorganisms such as bacteria and molds, and the product will not deteriorate in a short period of time, so it will not damage the skin. But if it is stored for too long, the nutrients in it will be oxidized and decomposed, and the effect of preservatives will be weakened.

In addition, in the past use process, it is unavoidable to be contaminated by the outside, so that microorganisms will multiply in it. If contaminated cosmetics are used, various skin diseases may be induced, such as local inflammation, acne, and stains. Therefore, in principle, cosmetics such as skin creams and creams that have been stored for more than one year should not be used again.
