Cosmetic life refers to the period during which a cosmetic product is safe and effective for use. Cosmetics have a “use by” date and a “shelf life after opening” (TAP) that indicate how long it is safe to use the product from the time it is manufactured and from the time it is first opened, respectively.

The shelf life of cosmetics may vary depending on the type of product and the ingredients used in its formulation. Some cosmetics have a shorter shelf life because they may be more susceptible to contamination or degradation of their ingredients over time.

All cosmetics with a minimum shelf life of less than 30 months are required to indicate the expiration date. In addition, those with a stable formulation that maintain their safety and properties beyond 30 months must indicate the maximum time during which they can be used safely after opening. This information appears on its labeling next to an open jar symbol followed by the time period in months or years.

Due to the humidity and oxygenation conditions of many cosmetics, it is possible for microorganisms to proliferate on them. In this case, a change in the texture, odor or color of the product usually appears so that the consumer can detect the problem and discard it.

In any case, quality cosmetics come prepared so that the likelihood of this happening is minimal. In case of contamination, product tolerance problems such as skin irritation or allergy may occur, which will be solved by discontinuing the use of the product.
