Why Do Skincare Products Expire?

Keeping track of skincare expiration dates might be the least important thing that I should keep track of in our daily lives. It's tough to stay on top of things when there are numerous skincare product brands available in the market, each with its own variation of expiry date. However, understanding the preservation period for skincare products is just as important as knowing how long could you preserve your food. And with the current trend of companies promoting naturally based ingredient skincare products, these products are more prone to be spoiling. So beauty companies use stabilizers and preservatives to maintain their product’s effectiveness and the general life span.

Reading Skincare Expiration Dates


There are a few things you need to know to understand the expiration dates for skincare products. First, the manufacturing date is the date that indicates when a product was made. Sometimes manufacturers may not provide the manufacturing date and instead use a batch code for their reference. In some cases, you might not see the manufacturing date labeled but the expiration date is typically required and presented.

Next, it's important to note the expiration date for most new and unopened skincare products. Typically, skincare products should have a shelf life of 2-3 years. When it comes to routine products like toners, cleansers, serums, and creams, it's more relevant to use the open-by date. However, for products like sheet masks, it's best to refer to the expiration date.

The Open-By Date and PAO Symbol


An expiration date is provided on skincare products as an open-by date. However, when trying to determine when a skincare product will go bad, the expiration date on the packaging is not the complete answer. The expiration date provides you with the open-by date for the product, meaning it's the last day you should open it. Technically speaking, the expiration date is the date before which you should open your skincare product. Open-by dates are generally more relevant for routine items that you'll use repeatedly over time. Once you open a skincare product, it's important to refer to the PAO (Period After Opening) symbol. This symbol indicates how long a skincare product can be safely used after opening it. The symbol looks like a jar with a number and letter inside. The number and letter is very self-explanatory where the number is the months and the letter "M" refers to months.
