cosmetic products


The shelf life of a cosmetics product is the amount of time that the product is considered good and safe to use. Though most cosmetic companies test their products’ composition and packaging for stability, there is no clear way to set an expiration date, because the manufacturer tests cannot take into account how Agents, and later on – Clients,  will use and store the products. Since the expiration of a product depends heavily upon the condition of product’s storage and use, expiration dates that are stamped on the package are nothing more than a recommended rule of thumb. Cosmetics may expire long before the suggested date if they have not been properly preserved or handled.

Preserving and Handling Cosmetics

Cosmetic products that have been misused or improperly stored can easily become contaminated. Once a product is contaminated, its composition has been compromised and it is no longer safe to use. Here are some of the most common causes of cosmetic contamination:

  • Sunlight exposure
  • Exposure to extreme heat or extreme cold.

Most cosmetics are photosensitive, i.e. they may be damaged by exposure to light. And humidity has the same effect.

If the product packaging does not specify other information on storage, it can be kept at the room temperature. In addition, it is mandatory to use the original packaging of cosmetics directly after use, close perfectly the container to prevent oxidation and evaporation of water by prolonged exposure to room air.

Cosmetic manufacturers say that, during periods of hot temperatures, some cosmetics can be kept in the refrigerator. It is generally about creams and lotions, but also about some makeup products.

But other products “suffer” when stored at too low temperatures and in an environment that can be wet, such as the refrigerator. For example, powder makeup should be always kept away from light and moisture, but never in the refrigerator, because it can easily deteriorate due to moisture. In contrast, organic creams, more sensitive to high temperatures and lower shelf life, are safe, if they are stored in the commercial fridge.
