1. Throw out expired product
We know it’s tempting to hold on to products that aren’t completely empty but when skincare products are past their expiry date, they can start to do more harm than good. The ingredients can break down or change their composition meaning they could start to irritate your skin, cause oxidisation (prematurely ageing your skin), or just simply not work at all.
Most products will have an explicit expiry date on them which is when they need to be used by. But, there will also be a mark on the label which has a number of months in which it should be used once opened. If not stored properly (perhaps somewhere humid, warm, or with the lid not on securely) this could mean they expire sooner. If they smell strange, develop a strange colour, or look different in consistency – it’s time for them to go.
