Your sunscreen package may have a jar symbol with the lid open to show when your sunscreen will go out of date. The open jar symbol will have a number and an ‘M’ on it which refers to how long the sunscreen will last once opened. For example, at the back of the NIVEA Sensitive Sun Lotion, you’ll see a ‘12M’ on the open jar symbol. Hence, this means that the sunscreen will last for 12 months once opened.
Lastly, an hourglass symbol on the packaging means that the product will last for 30 months from its manufacturing date, opened or unopened.
For example, if you notice a change in consistency such as it’s become more watery or clumpy, then it’s time to replace your sunscreen. Moreover, if you notice a change in smell or colour, it’s advised that you do not use the products and purchase a new one.
