Period After Opening
Have you ever wondered if your make up have expiration dates just like canned food or medicines? Make up have those as well too, but they are not called expiration date or “best before”, they are called “period after opening”. It’s a symbol usually found on the back to tell you how long you have until the make up expires. If it states a symbol “12M”, it means the make up is good for twelve months. A good tip would be using a permanent marker to write down beside the period after opening symbol the date you first opened or used the product.
